Battery Capacity of Common Devices
Comparing Battery Life
Battery life can vary widely in smartphones and tablets, so it’s helpful to know how much energy the batteries in popular devices can store. Look for the abbreviation mAh as a measure of how much energy a battery can store – and understand that a charger’s stated mAh never is fully transferred to an attached device, because chargers require a percentage of their own battery capacity to operate.

Power Bank USB Output
Tablets and Smartphones typically have different power needs in how much power they draw from a power bank. For tablets and iPads, it is typically 2.4A and for Smartphones and iPhones, it is typically 1A. A charger with a 1A output will still charge a tablet but at a slower rate. If you need speed in your charging, we would suggest an uprgraded power bank with a 2.4A output option. Some of our higher end power banks come with 2 USB outputs including 1A and 2.4A and have larger batteries that can charge more than 1 device at a time!
Power Banks Basics
Milliamps often interchanged with Milliamp Hours, or mAh, is used to describe the amount of charge a battery will hold. This will also determine which devices can be charged with the Powerbank you decide on choosing.
Amp Output , abbreviated as “A”, determines how fast your powerbank will charge. For example, a powerbank with .5A output will charge your mobile device slower than one with 1A output. Some larger devices such as a tablet can only be practically charged with a powerbank with a 1A output.

2200mAh – Standard powerbank capacity. A powerbank with a 2200mAh capacity will comfortably charge a standard mobile phone. Smartphones and tablets won’t be fully charged.
2600mAh – Standard powerbank capacity. A powerbank with a 2600mAh capacity will fully charge most new phones, such as the Samsung and iPhone5 mobile devices. They will comfortably charge tablets, albeit not to capacity.
4400mAh + – Plus sized powerbank capacity. A powerbank with a 4400mAh capacity willl have enough power to charge most tablets. Powerbanks rated at 4400mAh will typically be larger in size, due to additional battery cells.
8800mAh + – Plus sized powerbank capacity. A powerbank with a 8800mAh capacity willl have enough power to simultaneously charge two mobile devices. Powerbanks rated at 4400mAh will typically be larger in size, due to additional battery cells.These powerbanks will also come standard with a 1A output.
