With the Sandberg Survivor Power Bank 10000 PD20W in your luggage, you won't run out of power on your phone or other portable devices when you're far away from a socket. You get up to 4 charging cycles for a typical smartphone and with its solid and waterproof exterior it keeps going even under harsh conditions. Charging status can be read easily using the LED lamps on the top. Qi-compatible smartphones can be charged completely wirelessly by placing the phone on the charging plate on the powerbank.
