that s a good charger for field usage on low capacity battery
I use 4 of those chargers.
It starts working as soon as pugged to the lipo.
Just showing voltages.
Its difficult to see whether power ist on or not.
IF THE POWER IS NOT ON it will discharge 1 or 2 cells down to ZERO in a day or 2.
(Thanks HK for not warning - loss of one of my 4s batteries.)
Cells up to 2200mAh are good to charge. Bigger need a lot of time. A 4s 3300mAh needs about 2h's.
I whished to have such a charger with the posibilty to leave it on the lipo all time and that it discharges the lipo to 3.5V per cell (safety) - 2-3 hours before flying i power them and get fully loadet and ballenced.
Well, I bought 4 and 1 is still reading voltage but no charging.
3 units just burned up the transistors from either small voltage
surge or possibly my mistakes. Either way they have poor isolation
from voltage surge or any momentary wrong connection.
If you buy them you may get error messages as they are also fussy about
the power supply input. They work if you are extremely careful but
one just fried from normal connection spark when hooking it up.
I like the concept but feel they are a little too sensitive with no apparent circuit
protection. If they did an upgrade I would buy more as they have a good readout and the case is good. But 4 fails is a bit high out of 4 units purchased.
Hope they improve these or remake them with more durable circuits.
Be very careful with them and maybe they will serve you well, but I am not too impressed at this time. Sorry Hobby King, this item needs some work. 2 out of 5
crowns just for the good concept.
Perfect quality and very small, you could any battery 2-3-4 cells, only I need adapter of the 15v and 2amperios to my lip 1400mah 4s
Very simple but practical. Balance charges well. Unable to select charge rate but it charges a 1000 mAh 3s battery in roughly 40 mins (from 15pcnt).
I love this charger. Plug in power, plug in battery, wait for the fully charged beeps. Jobs done. So simple Also doubles as a battery voltage meter when not plugged in. Can't beat the simplicity as well as the price.
Highly recommend this product for anyone who wants to get a clear cell check 2s~4s in the field, park or track, to me the balance charger is a bonus and a very effective one at that.
fits in your pocket no trouble and very simple plug and check no buttons or settings.
This product is great. It takes about 2h for a complete charge of 2.2A battery with a DC supply of just 24W (not >30W like the label of the charger says). So... it's great!!! :D
I was expecting a big boxy charger. This thing is TINY! and for the price!? can you please find any charger that does what this will do for the price? I am definitly going to order another to put in my tool box as an emergency field charger. Currently I'm using it at home and would like another one. EXCELLENT!
great charger / battery checker. Does not come with wall charger, so you'll have to supply that yourself. I just use a 16v 1.2amp wall charger I found goodwill for $3. It is also nice because it displays current voltage as charging and notifies you when full.
