WARNING: this may overcharge the batteries, but as NiCd and NiMH batteries dissipate excess power as heat, I don't think it will be a big issue. And four batteries in series would charge up to 1.25V each, which is pretty good. But charge through a 22Ω resistor to limit the current so the batteries won't overheat in the end. Or use some NTC thermistor and relay latch system. If the temperature rises too much, the NTC will decrease its resistance, which will turn the relay latch on or off, depends on your relay, ending the charge process. Even the thermistor option will work well, you'll just have to use a PTC thermistor instead. But it wil keep powering the charged battery which will heat up a bit.
Here is the formula for the time it takes for the battery to charge A --- = C B A ÷ B = (C ÷ 60) 1000v ÷ 5v/s = (200 ÷ 60) =3.33... minutes =3 minutes and 33 seconds Not flexing but I'm only 15 years old, hehehe
Leally amazing
Nice 😇

Does it charge chargeable cells or any AAA batteries ?
Very very nice video
1 battery take how much time
Is it safety to try this bro?
Nope it's not because you can over charge the battery and it will mean you get less recharge cycles
do it with pc not mobile charger causing fire blown
If your batteries have move voltages than what USB Adapter can support it can explode the adapter and may even cause a little fire.
4 of 1.2 volt batteries =~5 volt adapter. Why fire can happen?
Charging full how to know Multimeter and check only know
Here is the formula for the time it takes for the battery to charge
A
--- = C
B
A ÷ B = (C ÷ 60)
1000v ÷ 5v/s = (200 ÷ 60)
=3.33... minutes
=3 minutes and 33 seconds

Indian?

No one's impressed. Stop trying to flex.
Can someone tell me if this is legit?
