Laser PB-CJ12000 Universal Power Bank Battery
Rechargeable 12,000mAH With USB, Car Starter, Led Flashlight
What makes our Car Jump Starter Powerbank different? Well it boils
down to quality components, safety and features?
Within built circuitry for over-current, short-circuit, overload,
over-voltage, over-charging and reverse polarity you can be assured that you,
your equipment and your car's sensitive electronics are protected. Furthermore
all Laser powerbanks are certified safe to use and are compliant with Australian
electrical safety guidelines.
Our powerbanks are precharged which means out of the box they are ready to
Using high quality Lithium cells with maximum efficiency, our Powerbanks hold
charge longer and typically return more than 75% charge after 6
months.(*dependent on storage conditions)
The charging tips and chargers are included
Yes, in the (hard case) box, we include popular 9 pin (for newer Apple
devices); 30 pin (for older Apple Devices) and Micro and Mini USB (for most
other devices). Simply connect the multi plug cable into the PB-CJ12000 and
charge away. For car starting, we include heavy duty car alligator clips (Red
and Black colour coded) which has built in safety circuitry in the cable. In the
pack we also include a 240v Home wall charger and a 12vDC car cigarette socket
charger (note - to fully charge the power bank, you will need more than 7 hours
using the wall charger - hey, it's 12000mAh - that's a lot!)
High Power output gets your devices charged FASTER
With 2.1Amps (10.5 watts) of power output from the USB port, your devices
(especially tablets and larger smartphones) will charge faster
Start your engines
With 400CCA'S (Cold Cranking Amps), you can start most engines (such as 4, 6
and some 8 cylinders as well as many diesel engines). This includes cars, boats
and motorcycles(12v). In fact, you dont even need the dead / dying battery
connected. The PB-CJ12000 will start a car without the car's battery *(just on
the power bank alone).. NOTE: the power output for vehicle starting is 12v DC.
It will not work on 6v systems (like some motorbikes, watercraft and machinery)
Up to 20 car Jump starts and 7 smartphone charges
With 12,000 mAH of capacity,in independent testing, we've started 20 cars*
with no car battery connected. So imagine the benefits here, it will not only
get you back on the road, but you could re-start your car if you had to pull
over or stop (like to get petrol). *(the test was conducted on typically newer 4
cylinder cars) older cars and/or big engines may not offer the same number of
charges due to the current required to turn the starter motor. Some later model
V8/V10 luxury vehicles with a lot of electrical ancillaries may require a
different jump start cable/plug)120000 mAh also gets your smartphone charged
about 7 times and your new tablet charged fully with some left over.
Powerful LED flashlight and emergency strobe light
With 86 lumens of lighting power the small yet powerful LED light can help
you see at night and is a handy all round torch. You can get up to 120hours of
torch only use making it great for camping.For attracting attention the LED
light becomes a strobe (flashing) light as well.
LED charge status lights
Check the remaining capacity or charging status with the LED status lights.
The PB-CJ12000 weighs less than 400 grams (so you can easily put it in your
backpack, case, handbag (if you have a big one) and desk drawer. It also comes
with a handy hard case if you want to store it away or take the complete kit
(say if you go camping).
The LASER PB-CJ12000 Portable Power Bank and Car Jump Starter is the big
daddy of Power banks. Firstly, it's a power bank which has the power to FAST
CHARGE smartphones, tablets and other USB powered devices. Second, it's a car
jump starter and has enough power to get your car up and running from a flat
battery. Lastly, it has a high intensity LED flash with a strobe function, just
in case you need to attract attention. The PB-CJ12000 is lightweight and small
enough to fit in your pocket, handbag, car glove box or desk drawer. The high
quality Lithium cells gives you up to twelve months of standby time, and
multiple in built protection circuits ensure safe usage for you and your
So how does such a small powerbank get something like a car
Without getting too technical it's all about the CCA power and how it's
converted into 12v charging current. Older type batteries (like nicad and nical
metal hydride) are bigger, heavier and much less efficient. That's why Lithium
is used in virtually everything from phones, tablets, GPS, cameras and even the
latest electric cars like the Tesla. So using the latest in Lithium battery
technology, some smart circuitry and safety cutoffs, you can effectively jump
start most cars (or boats/ motorbikes) with this powerbank.
What are the variables in output power?
There are many variables in determining how the Car Starter Powerbank
performs. The biggest is the way it's stored (temperature variations reduce the
battery holding capacity and reduces it's efficiency). Also, for late model cars
with lots of electronics and convenience features - the current drain is quite
large so it would be best to turn off ancillaries like air
con/radio/lights/heated seats and so on to get the best performance when jump
starting your car from the powerbank. Typically a larger car with many
convenience features (such as a European luxury car (V6/V8/V10)) may get less
than 10 starts due to the amount of current required just to run the
How Power Output is delivered
The three most common values used when discussing electricity are; 1) Voltage
or “V” (measured in volts), 2) Resistance or “r” (measured in Ohms) and 3)
Current or “I” (measured in Amps) When applying these terms to Consumer
Electronics, we most commonly hear about them being applied around products like
USB charging devices. In this application most of us know USB runs on about 5.0
volts. Resistance, well, resistance is very rarely used and of little interest
however when compared to current. Current is very important as it describes the
strength of the voltage or how fast it flows. If you consider your garden hose
as an analogy - voltage would be the width of the hose, the current would be how
fast the water flows through it. Eg. You can fill up a bucket of water faster
when you turn the tap on faster. When talking about wall plug USB chargers,
built-in circuitry converts the 240 volts mains power down to 5 volts (for USB)
and in varying currents or amps. Car chargers also do the same this, however
they convert 12 volts down to 5 volts also with varying strengths. Early
chargers only had fairly modest outputs of about 1.0 amp, however modern
chargers can now output up to 2.4 amp which effectively can charge a device in
almost half the time. This 5 volt USB power can also be used not only charge
your smart phone or tablet, but it can also be used to charge portable power
storage devices called power banks. These power banks can also deliver varying
amounts of current or amps however it is measured in a slightly different way,
called Milliamp Hour or mAH for short. Eg if your smart phone has a 5,000mAh
battery, you can get up to two full charges from a power bank that can hold up
to 10,000mAh of power.
Did you know?
We use batteries to charge most of our portable electronic devices (PEDs),
but they can have serious safety consequences if they're not carried correctly
when you're flying. For example, in 2014 in Melbourne, undeclared lithium
batteries were packed into a passenger’s checked bag and short-circuited,
igniting a fire in the aircraft’s cargo hold before passengers boarded the
flight to Fiji. Since then, there has been various types of safety materials
produced, that help passangers make sure their luggage is safe, even including

How to carry batteries safely
Watch the CASA safety video - Travelling safely with lithium batteries.
Batteries under 100Wh rating
- The batteries that power your phone, laptop and camera are usually under
the 100 watt-hour (Wh) rating.
- If you're carrying a spare battery that's not in one of these devices, it
must be in your carry-on baggage only.
- Spare batteries, regardless of their size are not to be carried in checked
Lithium Ion batteries 100-160Wh rating
- These are more powerful batteries, and can be found in industrial
equipment such as power tools and mobility aids between 100 and 160Wh.
- You must have approval from your airline before flying.
- If the battery is installed in a device, it can be carried in either
checked or carry-on baggage.
- If the battery is a spare - that is, the battery is by itself and not
contained in equipment - it must be in your carry-on baggage only.
- Spare batteries, regardless of their size are not to be carried in checked
- There is a limit of two spare batteries per person. These batteries must
only be packed in carry-on luggage and should have their terminals
individually protected to minimise the risk of contact other metal objects in
How to protect your battery from short circuits
Short-circuiting batteries have been responsible for numerous on-board fires,
so its important that all spare batteries have their terminals protected
You can do this by:
- Keeping batteries in original retail packaging or
- Insulating the battery terminals by taping over exposed terminals or
- Placing each battery in a separate plastic bag or protective
We also demonstrate these techniques in our safety video above.
Lithium Ion batteries 160Wh rating and above
- You can't carry lithium batteries above 160Wh unless they are for
wheelchairs and other mobility aids.
- These batteries must be transported as declared dangerous goods
Please contact your airline for guidance.
Whats your watt-hour rating (Wh)?
- Most modern batteries have the watt-hour rating (Wh) displayed on their
casing so you can see how powerful they are.
- Some older models might not have their watt-hour rating clearly displayed
but you should be able to see the voltage and amp hour which will make
calculating the watt-hour simple.
- To calculate your batterys watt-hour rating, you multiply the voltage (V)
by the amp hour (Ah).
- For example, a 12 volt battery with a 5 amp hour rating will be 60
watt-hours. V x Ah = Wh.
- If the battery is rated in milli-amp hours (mAh), divide your final answer
by 1000 to arrive at the watt-hours. V x mAh / 1000 = Wh. For example, a 6
volt; 2500 mah battery will be 6 x 2500/1000 = 15 Wh.
Buying batteries online? If it sounds too good to be true,
it probably is
A lot of counterfeit goods are sold online and with batteries powering most
of our personal devices, there's a high demand for spare, replacement and
second-hand batteries. Unfortunately, electronic counterfeit goods do not meet
stringent safety standards and pose serious dangers to the end user.
The best way to make sure the battery youre buying is genuine is to buy it
from a reputable, well-known buyer. If you're going to purchase a battery from a
lesser-known distributor via the Internet, always keep the following in mind:
- Price - if its too good to be true, it probably is.
- Make sure the shrink-wrap on the exterior is tight and professional.
Auction sites offering products with no box or manual, no warranty or
documentation, are usually counterfeit.
- Any cheap, faded, damaged packaging, labelling, strange markings or
misspelled words are also signs of counterfeit products.
- Ask the seller if youre buying a genuine product.
- If youre still in doubt - dont buy it.
Example 1 - Spot the difference
Can you spot the fake? Counterfeits are becoming so convincing that the only
indicator may be the price. In this case, the battery on the left is genuine
article, with the one on the right produced by a counterfeiter.
Looking after your batteries
Damaged batteries can be dangerous. Whether theyre dropped, smashed,
overheated or mistreated in other ways, lithium batteries can become unstable
and have been known to ignite fires due to mistreatment.
Batteries show clear signs of being unhealthy. Such signs include:
- Spilt case
- Leaking fluid.
If your battery shows any of these signs, it should be replaced. Its also a
good idea not to travel with your batteries fully charged. Keeping charge levels
at 40-70% will keep the particles that store energy in their most stable state
during travel, minimising the risk of thermal runaway.
Batteries don't last forever and its important to monitor them. Continual
dischargers, over-charges and quick-charges will eventually reduce the batterys
overall capacity and health.
Example 2 - Discolouration
Example 3 - Bulging caused by overcharging
Example 4 - Split casing
Example 5 - The difference between new and old batteries
Safety is the first thing that jumps to mind when buying a Power Bank. The
main component of a power bank is a lithium ion / lithium polymer battery and by
nature they can be a little temperamental. Although they are one of the most
commonly used types of battery today, safety is still treated very seriously.
There are two parts of a power bank that are of specific interest, these are:
1. Battery Cell quality
A Grade A battery cell is a common industry term used to describe a quality
battery made from premium materials and made using leading manufacturing
processes. The real measure however of a batterys quality is, whether it has
undergone and passed UL Certification. Even though power banks can be tested to
many different certifications, the most comprehensive is the UL Certification
test called UL1642. UL1642 is a set of rigorous Electrical, Mechanical,
Environmental, Fire and Heat Exposure tests. UL is the most widely accepted
certification that ensures a batterys compliance with world leading and globally
recognised safety standards.
2. Protective Circuitry
The Protective Circuitry or PTC (Positive Temperature Coefficient [circuit])
is considered a Safety Valve that protects equipment against excessive current
from external short circuits, abnormal charge/over charge, forced discharge and
other dangerous conditions by directly reacting to rapid increases in current by
physically impeding the energy flow, then returning to a normal state once the
excessive current has passed.
Its easy to reduce the costs of power banks by cutting out the cost of
battery certifications and protective circuitry, but by doing so creates a real
risk to the safety of the power bank, any connected devices and even the end
THE 3 MAIN TYPES
How do I choose the right type of Power Bank for my customer?
The first step is to know what your customers expectations are. In general,
power banks can be categorised into three main types based on capacity and
usage. Single charge batteries, multiple charge batteries and specialty power
banks that can jump start cars and power notebooks and laptops.
1. Single Charge:
This category of power bank provides the lowest capacity and price.
2200 mAH is the most common capacity adopted by the market.
Single charge power banks are ideal as an emergency backup for charging
phones. These smaller capacity power bank batteries however do not have enough
capacity to fully to charge an iPad, tablet, or other devices which have higher
capacity batteries. (they may give you only 10%-20% for an iPad Air 2 for
Phone batteries vary greatly in capacity so it is important that you
understand the battery capacity of your device and the capacity of the power
bank you intend to purchase. Smaller capacity power banks (<2000mAh) (when
compared to a device battery capacity like an iPhone 6) may not provide a full
charge for a device as it depends on many factors such as age of the phone,
power bank, level of charge and so on.
2. Multiple Charge
Multiple charge Power Banks cost more than single charge Power Banks as they
can charge multiple devices or multiple devices at once, with significantly
larger battery capacities.
The Capacity ranges from 3,000 mAH to more than 10,000 mAH.
Power banks in this class are able to charge phones and tablets, many of them
equipped with two ports, one for charging phone and other for Pad or Tablet.
3. Specialty Class:
Special Class Power Banks can charge multiple phones and tablets and also
laptops and notebooks and some can even start up your car when the battery has
Special Class Power Banks have very high capacities and models can be
tailored for specific uses.
Special Class Power Banks cost more compared to Single and Multiple charge
POWER BANK FAQS
How long will it take to charge my phone or iPad?
Charge time depends on the battery capacity of your device. In general, the
larger the battery the longer it will take to charge. It is a common
misconception that a larger capacity power bank can charge a device quicker,
this is not the case. No matter the capacity, all power banks will deliver the
same amount of energy to a device over a same period of time. So, if you have
two phones that are exactly the same and one is being charged by a 2200mAh power
bank and the other by a 6600mAh power bank, both will receive the same amount of
charge at the end of one hour. The only difference is that the 2200mAh will have
less charge left over than the 6600mAh power bank.
How long will it take to charge the Power Bank itself?
The same principal applies with charging a device the larger the power bank
battery the longer the charge time, however, a 2200mAh power bank may take only
2?3 hours to charge, whereas a 6600mAh power bank may take up to 3.5 hours to
charge. Using a wall charger will give you the best results because it outputs a
higher capacity charge than a PC (USB socket). A PC socket can typically
delivery 500mAH of power whereas a wall charger can commonly provide up to
2400mAH of power (Note: As mentioned before, safety circuitry can restrict the
flow of current to a device if excessive, so usually anything over 2400mAH will
not see any improvements in charge time)
How many times can a power bank be cycled (recharged)?
Depending on the age, condition and class, a power bank may be cycled up to
300 to 500 times. Over time however, the capacity will slowly decrease and
eventually need replacing, much the same as you see with a typical smartphone or
tablet. A power bank when not in use or put into storage for extended periods
should at least have an initial charge of about 50%. Storing a power bank
without any charge will dramatically reduce the overall life expectancy of any
What kind of cable comes with the power bank?
Most power banks come with a simple USB cable that is only used to charge the
power bank itself. Some LASER products however come with charging cables that
will suit multiple devices such as old and new Apple devices and devices using
micro and mini USB connections.
Why is there different input and output sockets?
The input, which is usually a Micro USB connector socket, is used to charge
the power bank. The output socket is most commonly a normal size USB socket.
Simply plug your devices charging cable (USB side) into the power bank to begin
charging your phone or mobile device.
How many phones will a Power Bank be able to charge?
As the above name roughly suggests that a single charge power bank may charge
up one device and a multiple charge power bank can charge up to 2 or 3 devices.
The best way to calculate this is to match the capacity of your device with an
equally or larger size capacity power bank. In this way, you are all but
guaranteed one full charge from your power bank.
Does a power bank work with both iPhone and Android phones?
Yes. Essentially a power bank is just a battery which is connected to a USB
socket. There is no software or hardware to cause any system compatibility
issues. As mentioned previously though, you do need to be aware that matching
your device with the correct capacity power bank is very important.
Do you carry a charging cable that can be used with my
Most phones and tablets come with their own USB charging cable. LASER however
does include charging cables which suit multiple devices (such as 30 pin, 9 pin
and micro USB).
TIPS AND TRICKS
One simple but important reminder
To prolong the battery life, always keep it fully charged where possible. It
is also a good habit to get into, and charge any new battery overnight.
How do I prolong the life of my power bank?
Avoid storing power banks in extremely hot or cold environments. Always store
your power bank with at least a 50% charge and avoid storing your power bank is
it has been completely drained. Keep your power bank out of reach from children
and be careful not to drop, break or otherwise attempt to disassemble it.
Internal components can be harmful if tampered with incorrectly.
Charging your Power Bank in your car
Avoid connecting a power bank to a car charger until the car has been
started. Many car chargers on the market may not be able to safely handle the
sudden peak of current during vehicle ignition and may damage the power bank.
What does Power Bank Capacity mean?
Power Bank capacity refers to how much charge can be stored in a power bank
battery. It is measured in mAH or milliamps per hour. It is also important to
note that when a power bank is charging a device, some of the energy is lost in
the transfer. In simple terms, it takes energy to transfer energy. So, the real
capacity of a power bank maybe off by a factor of 10 or 20%.
Does a High Capacity Power Bank charge a phone faster than a Low
Capacity Power Bank?
No. The charge speed is determined by output current, not the capacity. (An
even more accurate answer actually would be what the safety charging circuitry
of a device limits the charging current to)
