2.4amp charger and Mvp20w

[morningdew]

As I now have a couple of mods which take 18650 and 26650 batteries, I have been reading up on battery safety - @Mooch thank you for your excellent posts.

Bought a xtar vp4 and batteries from reliable sources, Have made sure using ohms law that I am well within the battery specs, bought plastic cases for batteries, am checking battery wraps for any damage both when charging and putting in / taking out of mod etc

However, going back to the old built in battery mods, I was led to believe that the charge rate is determined by the device being charged...reading of many battery incidents being due to people using the wrong charger, I started to wonder is that due to to high an amp rate for the charge.

I have a 5 port Iclever adaptor, 2.4 amps per port, 10 amps maximum.

Been using it to charge mvp20w (2200mah), cool fire 4 plus (I think 3300mah) and an mvp3.0 (3600 mah ?).

My understanding being that amp to mah is approx. 1 amp per 1000mah maximum charge rate.

Question's are;

- is it ok to charge the mvp20w on the 2.4 amp ports, will the device limit the current or is it actually too high a rate?
- as the cool fire and mvp3.0 age they will reduce in mah, are they safe to continue charging on the 2.4 amp ports?

Note i am using the original sub cables that came with the mods.

Thanks for any answers...

You can safely charge with a 2.4A USB wall charger. The device being charged will only draw its design current load.

Devices draw current based the resistance of the circuit being charged. Most USB charged mods draw about 800ma current because there's a current control resistor across the mod's input that limits it to a certain current draw. It's the same principle that lets you plug in a tiny phone charger to a 15A house circuit without damage. Your MVP and Cool Fire will draw the amount of charge current they need by design.

When charging batteries using a bay type lithium charger the charge current is either preset or controllable with a switch setting.

If you are interested in seeing the actual voltage and current draw on your USB devices the Volt/Amp meter below is a cheap solution to that problem.
