Charge anywhere.

Make sure you’re always connected with back up battery power that’s as mobile as you are.

Battery packs come in all shapes and sizes, smaller sizes for an essential smartphone boost in your pocket, or bigger sizes for multiple charges or to charge a tablet.

Choose one with cables included, or one with multiple ports to charge more than one device at a time.

Pick out a power fortress or something small and sleek, and take the power to charge anywhere, with you everywhere.

We’ve used smartphones and tablets to compare battery sizes, but most battery packs will charge any device that charges via USB, such as a GoPro camera, Kindle reader or Bluetooth headset. Bigger devices that draw more power will need bigger batteries - more mAh - to charge them fully.

How to ensure fast charging for your phone/tablet.

Technically the standard USB port on your battery pack will fit any standard USB cable. However, the amount of power it can provide may vary.

Optimal power output
Minimal Speed = Minimal Speed
Better Speed = Better Speed
Fastest Speed = Fastest Speed

Charge one smartphone Charge one tablet
1 AMP Better Speed Minimal Speed A 1 amp USB port will charge your smartphone or tablet but may charge slowly, even if the battery is big enough to charge your smartphone more than once.
2 AMP Fastest Speed Better Speed This will charge most smartphones at the fastest possible speed for smartphones. This is also called “optimal charging.”

Charge two smartphones Charge one smarthpone and one tablet Charge two tablets
2.4 AMP
Fastest Speed Better Speed Minimal Speed
  • Can optimally charge 2 smartphones at the same time.
  • If you connect a smartphone and a tablet, it will charge them both but probably not at the fastest possible speed.
5.4 AMP
Fastest Speed Fastest Speed Fastest Speed This has the power to charge 2 tablets simultaneously at the fastest possible speed.
* “Total,” “shared” or “combined” is usually used for battery packs with multiple
ports, and is the total power available from all ports combined.
Charging the battery pack


There is no such thing as a magic battery pack.

Unfortunately, no battery pack has been invented that magically recharges itself when it’s empty. But on the whole, they are pretty simple to charge.

If you need one immediately, check on the package if it’s ready to use when you buy it. Some will need to be charged at home before they can be used.

To charge, plug the supplied cable into the input port on the battery pack. Attach the other end, usually a standard USB, into a wall charger or other power source.

Battery pack input ranges from 1Amp up to 2.4Amps. Put simply, the bigger the input number, the faster it will recharge. Most wall chargers deliver up to 2.4Amps, but it’s worth checking the charger if you’re in a hurry, as a 1Amp charger might take twice as long.

Some battery packs have an LED indicator, which tells you how much power the battery pack has left. This will tell you when you need to recharge the battery.


  • Heat test at expreme tempatures
  • Over voltage protection
  • Efficiency
  • Robust quality assurance


A robust quality assurance offers durability and peace of mind.

Rigorous testing and thorough investigation of product performance make your battery pack more likely to last longer, and less likely to harm you and your valuable electronics.

Safe battery packs should have undergone the following testin


More efficient battery packs will have a lower operating temperature, which wastes less energy, giving it longer life expectancy.

Over Current Protection

OCP prevents too much power going into the battery pack and the power going out to the connected equipment, protecting the delicate circuitry of both devices.


Like OCP, OVP protects both the battery pack and the connected device by keeping the voltage within recommended safety parameters to avoid damage.

Over Discharge/Charge Protection

High-performing batteries should not be overcharged or fully discharged to prolong their life expectancy. Some battery packs consistently monitor charge states to prevent this from happening.

Heat Tests at Extreme Temperatures

While using batteries in extreme temperatures isn’t advised anywhere, it can be a good indicator of weaknesses in design and construction. Batteries which pass such stringent testing will be more durable and offer improved assurances of overall safety and performance.


Compliance with legal standards of safety.

These logos or marks, usually found on the packaging, will indicate that they have passed the necessary industry standard regulations, to comply with and achieve the following certifications.
