I don't think I ever mentioned 10w charging. I used a 100w usb c to c cable to test output. I got a max 42w at almost 3A when trying to charge a Samsung 22Ultra that was at 20%. I used this to test output. amzn.to/3VGEvHm These power bricks can vary in true output quit a bit depending on brand and make.
I could find no info on that. Definitely not in the owner's manual. I did test cells ranging from 2.8v to 3.4v. It took three charge/discharge cycles to get them close to balanced. So that tells me at least there is some form of BMS working. I would test each cell occasionally and balance accordingly to be safe.
It's only a 1s charger so i think the bms would only read the voltage of the cells as a whole. A flat battery would drain current from a fully charged battery.
@David-jx4gw ....and a full battery will be overcharged by the current still going to the lower batteries asking for power. Thinking it has battery balancing like the brand-advertised BMS is wishful associative thinking, and is in this unit's advertising because they hope you'll be fooled. China!! This is not a fully featured "battery management system", except that this "manages" the charge. Only if each battery has a separate lead will the BMS know what each battery's needs are. As well, it would be nice to be able to limit the charge to 80% or 90% to not overstuff the cells, and have a 40% storage mode. And set the discharge level. Now we are talking BMS. My four 18650's were $30 each, and I'm not risking burning them out on a 10 buk charger. The circuit should be easy to make by now, and should be in every single device, and probably will be soon. Like getting cold temp charging cutoff feature on expensive units, it takes a while for manufacturers to respond to customer demand. If someone else does it cheaper, they go out of business. They don't care about your battery or customer loyalty. Chinese manu's think they're losing money if they include a feature no one realizes they have to ask for, even though they need it.
@David-jx4gw wow, that's almost worse, no? In parallel the batteries will self-balance PRE BMS meaning no regulation at all. That would be disastrous for anyone popping in random cells or cells of varying voltages!
@@saintapoc4031 that's my concern, I will definitely buy a device that can safely charge cells of different types or/and voltage and allowing to use it as a powerbank
Can you hack and add a wireless charging?
You could if you wanted to.
10W is not the fastest newer phones can charge at

Not sure that the bms inside those can handle a high voltage difference between the cells, is there any info about that ?

Mine doesn't last long. I get like 20 percent and that's it
20% what? Charge amount? Run time? If it will only fill batteries to 20% you need to return it.
