Panasonic Eneloop SmartPlus USB Travel Charger (BQ-CC87) $39.02 + Delivery ($0 with Prime/ $59 Spend) @ Amazon UK via AU

Got a bunch of Eneloop batteries that need charging on the move? Or perhaps you would like to use your AA’s / AAA’s as a powerbank to recharge your phone, GoPro etc?
Then you may be interested in this device. Good deal on 3xC. $1.62 off best price.

NOT a fast charger. 1amp input and output, but thats a good thing for battery life.
