ECITA say that wall chargers that are rated higher than 500mA should not be used?

[sparkyjuice]

Maybe i'm being ignorant here but is the CHARGER not built into the battery device itself ?
(an ego type battery)
The 5v usb supply merely supplies the power to the inuilt battery charger/monitor ?
therefore even if the usb device is capable o supplying 10A the inbuilt charging circuit should protect the battery,
providing it is fit for purpose ?

I have half a dozen ego chargers, a few joyetech 420mA, a kanger 420mA, a kanger 500mA, and a few unbranded that are all 420mA... they all say the same: Input: 5v DC - and that's it - they don't specify a maximum amp input - because the way amps work from what I understand, devices only draw what they require. - it wouldn't matter if it was a 5v 50A supply (like plugging directly into the 5V rail on a PC ATX power supply).

Am I missing something in basic understanding of electronics? - that's a genuine question btw, not being sarcastic in any way (which is how it might sound, but it's not)

no I believe that is correct, wall socket s protected to 32A on a ring main...that does not mean you can draw 32A on a socket......
the principle is the same.

I believe that is the case with USB passthrough batteries, yes. - for standard ego batteries, the 'charger' is the USB to 510 connector cable.

Basically, batteries have a max charge amperage. 2.1amps exceeds this amperage. Battery goes boom.

I've just finished translating a piece of research into English that might concern you. To do with this stuff being produced at low ohms. I'll linky you when it's been put online.

But surely that is 5v unregulated ?
Or are you saying the charger is built into the cable ?

There is also this source of information - http://en.wikipedia.org/wiki/Battery_charger

yes, they look like this:

Yes I think I've seen that somewhere too.. I'm pretty sure Dr Farsalinos has mentioned it too. If I remember rightly he said it was another unknown., and cites it as a need for more research.I'm not too sure if his latest trial is looking into it or whether he'll need to do a separate investigation...
But it is a watch this space to the best of my knowledge.

yes, they look like this:

In that case the USB can supply 100A
and not make a blind bit of difference
as long as the charger is fit for purpose

Thank you for introducing yourself.

I note you say you're planning to be a vendor, will you be applying for vendor status with us?
