Does it's job without any problems, since many months. The only issue I had: the solderings on the baseboard torned down after pushing the plug a little to hard into the 4S socket. I took too much force, because the plug don't fit completely into the socket, which confused me and I thought it wouldn't be connected completely. (As it turned out, that's just the design and the plug have sufficient connection to the socket).
I had to solder the socket connections again to get it work. Since then no problems still!the perfect charger to keep your batteries ready to go an inexpensive easy to use charger to help your childs plane car or boat ready for action .. 2s-4s LiPo charging made easy .. simply plug into any suitable 12v power supply and you are good to go ..Carica batterie marca Turnigy B4 Compact 35W 4A con bilanciamento automatico pu caricare senza alcuna difficolt batterie LIPO/LIFE/LION da 2/3/4 celleGreat charger, but I was somewhat lead to believe it came with a wall adapter, and it doesn't. The input port isn't a standard 2.1mm dc barrel either, so it isn't like you can pick up any wall adapter laying around your house that supplies 12v. Other than that it is a good compact charger.Excellent 4S charger. 4 LED's and sound indicators. Protection circuits. The absolute best value that I could find for a single 4S charger. Included is a 12 volt supply connector with alligator clips and a 4S port plugs to XT60 Cable.
