perfect device, i use it very often

Jun 10, 2021

perfect device, i use it very often to discharge my Lipo's to storage mode by charging my cell phones. Cut off voltage 3.0V seams a little to low for best storage of my Lipo's. May i ask to modify to 3.8V / cell.

good with remark

would be fine to have adjustable end voltage of 3.8V to reduce voltage to storage value by charging the mobile

Never worked

Apr 14, 2020

Tried to use it to charge 3 different phones and multiple cables. All of them had the charge symbol come on, but never gain any charge.
I've tried to use it with 3s and 5s batteries.

may as well

One should consider a pack tester required equipment.
While your at it, it may as well offer that little bit extra by bundling a USB charger with it too.
! 2750 3S pack can keep a tinywhoop flying and an action cam filming almost all day long.
Since it is wise to take packs to storage level anyhow, you may as well get some use out of that power. Charge phones, run projects, and what have you in the process.

Brilliant

I use this to run my heated back brace which draws about 0.75amps and I get 5-9hours out if a 3s 2600mah lipo. It's been a godsend for me as it means my USB powered heated brace lasts longer than with the 4 AA's in the special case to run it which only lasts an hour. Phone charging usually draws at least 1amp if not more-if charging a cellphone I wouldn't use it while connected and probably turn the wifi off etc to minimize the power draw (which may well be why people have had issues charging phones. I hope they get them back in stock at Global soon cause I want another-love the LVC too. 5 stars from me.

Well I got this little cleaver thing in the mail some time ago. An now I have used it at an all week Airsoft event for charging my phone. DAM It gets HOT !!!! When charging new smart phones the charger got VERRY hot eaven with a 2S 2200mah lipo ... Personaly I cooled it down using my cold hands, and it was enough that i could charge the phone enough to keep it alive during the hole week ... So thumbs up for keeping my phone alive :-) But I don't thing i will eaver try to fully charge a smartphone with a 3 s battery .. I think it will get to hot ... But it doubles as a battery tester, so that's acturaly verry nice because it shows both individual cell voltage level plus total voltage level ... a verry nice feature..... Plus it's small :-)
