The Kea is a multi-functional power bank, hand warmer and flashlight, which can be charged connected to a computer USB port or electrical outlet. Never worry about being left without power, even on longer trips. The Kea will charge almost most mobile phones & tablets. With a high battery capacity of 5.000 mAh, you can charge a mobile phone up to 4 times. The Kea also has a hand warmer setting, using the stored energy to heat the aluminium outer shell (about 20 min. to heat up to 50°C, longer at extremely low temperatures). Also use the Kea as a flashlight by turning on the bright LED light in constant or flashing mode.
