[QUOTE="Dronason, post: 12898, member: 553"] In fact I tested with a wall mount AC power block that can deliver only 0.55A. It worked, start 12:00 and finish at 20:15 for a charge from 2 to 4 LEDs. The battery reached fully charge state and voltage was correct in Go4app as 12.76 V. A battery freshly charged in the hub indicate 12.85V. So it seems that Spark can charge the battery even with weak power source, it just take much more long. From a computer it don't charge the battery because probably it sees it as data link. The computer will not give full power if it didn't see any reason to do. May the OP had a bad USB cable? [/QUOTE]
