For 3.6V/3.7V or 7.2/7.4V battery packs or 2× 1.2V NiMH round cellsThe ingenious design of the Powerline Vario X makes it possible to charge almost all Li-Ion battery packs and Li-Po battery packs. Whether battery pack for digital camera or camcorder, the movable contacts can be adjusted accordingly and make the Powerline Vario the all-rounder.Alternatively, you can charge classic NiMH round cell batteries of sizes AAA and AA in pairs. This is an enormous advantage when traveling and on the move, as only one device is required for all batteries.Essential featuresThe voltage and polarity of lithium battery packs is automatically detected. Polarity reversal, short-circuiting or incorrect insertion of the rechargeable batteries is thus ruled out. After contacting the battery pack, the microcontroller-controlled charging starts automatically. With NiMH rechargeable batteries, you switch to pulse charging after the end of the charging process, so that the rechargeable batteries are kept fre
