I will start by saying that for the price, this charger is great. The complaints from other reviewers don't make sense in this price range.
I have put my NiMh and lipo batteries through many cycles and it works perfect. The lipo balancing is good, charges very closely to the stated capacities of the batteries and does it as quickly or as slowly as i choose (0.1 amp increments).
You will need to purchase a separate ac/dc adapter but there is a nice one that u can buy together "Replacement LCD Monitor Ac Adapter 12v 5a Power Supply with Cord". This adapter plugs directly in and works great and total cost is still lower than most other options. If you do purchase a different one just make sure its at least 12 Volt and capable of 5 Amps.
Straight out of the box, the unit is loud with beeps, but it took me all of 10 secs to find the user settings to disable the sounds. Now it is nice and quiet. You might also need to adjust the mAh cutoff if you have large capacity batteries (>5000 mAh) but that is easy as well.
Setup is easy, select battery type and amperage and hold enter.
Plan on buying or building the connector for your RC battery as it basically only includes the original deans connector.

Customer Review: Fixed my dead graphene battery
Bobby Blue
Fixed my dead graphene battery
My biggest complaint about this charger is how loud the button press indication and alarms are. This is a powerhouse of a little battery charger and you would think that all of the intelligent charging and whatnot would just get in the way and possibly stop you from charging a problematic battery, but its actually the opposite, but more on that later. As far as I can tell this charger can put out a maximum of 5 amps even for a 6s battery, or at least the menu lets you program it to do that. The power supply is separate and not included for this charger, but I actually prefer it that way because the model with the built in 120v supply is a little undersized. The power supply I used was a 72 WATT DC 12V 6A brick and in order to keep it from getting too hot I kept my output for my 4S charging at 3 amps. My only complaint is the cables that come with the charger don't include an XT60 to banana plug cable. It does come with a banana plug to a flimsy alligator clip cable which I used while waiting for my XT60 adapter to arrive.About that problematic battery charging, a friend and I both bought some nice $35 graphene batteries and they were dead on arrival, unable to charge. Regular chargers that just have an led for each cell wouldn't charge these batteries because they had a dead cell. When I plugged them into this charger it even said the first time that I had a 4s programmed but I had a 3s plugged in because it couldn't see voltage for one of the cells, but it gave me the option to charge anyway so I did and I checked the cell voltages screen and sure enough the cell voltage was almost 0 but rising quickly, then it threw a battery error and stopped. The video attached is the 3rd or 4th attempt and after 5 or 6 tries it finally got the cell above 3 volts and charged it like normal. Now these problematic batteries recharge on all the simpler 4s chargers as well. So this charger saved about $30 by being so cheaply priced and another $70 by fixing some dead batteries.
