This lithium-polymer battery pack has an enormous 4000mAh capacity (1500mAh is often typical). Thanks to the 2.1 ampere charging current (instead of the more typical 1A), it supplies even power-hungry tablet PCs with enough power for approx. 5 hours of operation in just a few minutes. And just 12 hours of daylight are enough to fully recharge the battery pack. And even less time is required if you use a PC or the separately available mains adapter (4 or 3 hours, respectively).
Also perfect as a mobile charging station for your mobile phone, digicam, MP3 player, etc.
As it’s only about the size of a wallet it’s easy to always take your power source with you. Charge your mobile electronic devices via the USB output (by connecting your USB charger cable) or by using the supplied adapters (mini-USB, micro-USB, Apple (iPhone 3, 3G, 4 and 4S), and Samsung Galaxy tab). The battery provides enough power to completely recharge your mobile phone 2-3 times. With LED charging status indicator. USB spiral cable, pouch, and carrying strap. Measures 16 x 8.5 x 1.2cm (6 1/3” x 3 1/3” x 1/2”, weighs 170g (6 oz).
