With this compact power device, you can charge up to 8 AA and/or AAA batteries. Additionally, the extra USB charging port allows you to charge your phone, smartphone, MP3 player, etc. You can first discharge batteries that are damaged or have weakened after long storage, and then recharge them. This way, you can refresh these batteries and increase their capacity.

The battery defect detection feature in the Powerline 8 ensures that defective and incorrectly inserted batteries, as well as disposable batteries, are recognized and not charged. The charging status of each battery is indicated by multicolored LEDs. Thanks to modern, microprocessor-controlled charging technology with multiple overcharge protection, the device automatically switches to pulse maintenance charging after the battery charging is complete – ensuring optimal performance and a long battery lifespan.
