A few days ago we took a look at some of the latest battery banks from Anker. With the new PowerCore banks being released Anker has decided to deeply discount the previous models. The 20000mah PowerCore 20100 battery banks still gives you days worth of battery power in a compact package. While it does not include support for Qualcomm quick charge it does include PowerIQ Technology and Voltage Boost give you the fastest charge possible. You can recharge the battery bank in only 10 hours with a 2 amp charger. This is one of the safest battery banks around with the included MultiProtect Safety system. This is currently on sale on Amazon for only $26.99!
