Got myself one of those just two days ago (from Banggood). Seems to work fine - charges up to 4.19v
But I’ve only tried it on an 18650 cell so far. Gotta try it out on my NiMh batts soon
For the price I reckon it’s a pretty good deal :innocent:
All of mine read 4.26 at termination. But in reality the battery measures 4.19 to 4.21 volts with a DMM when pulled off the charger. When charging a battery, one must have a tiny bit more voltage than the cell in order to charge it. I am not sure that this is a problem.
I like this charger its easy to travel with. Doesn’t over charge or anything. But my powerbsnk feature is faulty on my unit. I plan on buying a couple more and testing them out. It will say a 3400 mah battery is drained in under 30 mins. To charge my phone need to use like 3 full NCR b in a hour but when I pop them into my vc2 they still show 60+% capacity left. And only take back in around 1000mah
And it gets extremely hot using the powerbank function. So don’t really use the powerbank function on mine. I use a powerbank instead. But when it says the batteries are drained if I ler them sit for a little bit and put the battery back in go back up 3 bars and start charging the phone again. And decline rapidly again.
Seems like a isolated issue with mine never seen anyone else have problems with the powerbank function. I’ll see on my next one if it works properly. But charging lithium and nihm works great. Not going to find a charger for $3 that charges 4.2/4.35/lipo/nihm
Don’t own any 4.35 but one day I may. This Christmas I plan on giving a couple out as gifts with a budget light.
I’ve never tested the powerbank feature on mine. I’ll have to try it. What phone do you have, and at what charge level did you try charging it at? I’ll check mine out when I have a chance.
It does charge all four types: NiMH 1.20v, Li-ion 3.70v, LiFePO4 3.20v, and Li-ion 3.85v.
Put the cell in and the four blue LEDs cycle.
Click when the blue LED next to the correct selection is lit.
Then it switches to showing approximate amount of charge.
If you don’t manually select, it defaults— it will select either NiMH (it identifies those correctly) or Li-ion 3.7v (it would overcharge LiFe or undercharge 3,85v Li-ion)
This is explained in HKJ’s review, but I never understood it until recently.
I have a zte maxx I’ve tried charging at .5 and 1amp. Mostly 1 amp. I’ll try a few different cables. The cable I use reads 1.50 charge on my tomo v8. The highest current my phone can handle. But as some else suggested I’ll see what happens, but it shouldn’t be reading a 60-70% battery as fully discharged regardless of the cable. Mine also gets very hot discharging into a phone. The few times I’ve actually had to use it. I grab a 4 pack of 18650 to do it. (Batteries are under 6 months old and ivr checked with the vc2 voltage when the liito says fully discharged)For a $3 charger on sale I can’t expect perfection. As long as it charges correctly which mine does is the most important feature. I just wanted to state my experience. But here shortly in the next few hours I’ll test it again with 3 cables and see. Have to run my phone down first. I ended up buying another tomo v8 one for me and the wife. With 2 kids under 3 not always possible to sit by a wall chargers at all times.
