This pack contains one 3.7 V lithium-ion battery rated at 1400 mAh and 5.18 Wh plus a triple USB charger with an LCD status display. The charger powers three batteries at once from any 5 V 2 A USB source such as a wall adapter or computer port.

1400 mAh capacity decides runtime

The 1400 mAh cell determines how long a handset operates between charges. Buyers needing longer talk time should look for a higher-capacity replacement if their handset supports it.
