Hi Mervin, A ER2 message on this charger is a power supply error. The problem with your HAMA AC/DC Adaptor 12V 500mA supply may be that it's a charger pack for something like a cordless phone and the output isn't actually 12V, but fluctuates because it's meant to charge devices with rechargeable batteries inside. You can check this with a voltmeter if you have one. The other problem is your power supply only puts out 6W of power to a device which operates at 30W. The voltage is probably sagging or fluctuating because of the strain of trying to power this charger. Cheers, EA!

Would this be good just as a onboard cell meter

Hi Joshua, There are much lighter cell checkers than this for on-board applications. This is primarily a charger and weighs a LOT more than some of the dedicated cell checkers designed for on-board use. Cheers, EA!

2 thumbs up!
Not a good charger. My charger is not charging my LiPo's anymore. It doesn't come with any manual or any review and it is giving errors that are totally unknown like "Er0","Er2". For warranty it costs very much than the charger cost.

Do not order these pieces of crap. They fail within 1-2 weeks, and return shipping is nearly (or higher than) what you will be refunded.

Excellent charger! Kind of like the CopterX charger but better. 1) End voltage from charger 3s 750mah: 4.20, 4.19, 4.19 2) Charger beeps when battery at full charge 3) Can use this as cell checker at the field Very handy item. Get warm just like most basic chargers, that's fine. Does not overcharge or undercharge, which most other similar chargers have (CopterX, ESky..)
