I wonder if the general situation is a bit like the market for USB
mains chargers.

It's hard enough to get one of those chargers that actually
delivers the specified current rating, no matter how carefully you
shop to get the genuine article. Counterfeits seems to have a
stranglehold on the market. Which leads me to think that if the
current rating is faked then so might the safety approvals.

All this certification is only useful if fakes actually get
stopped.

Must admit to not having had a problem with a USB charger - but have
heard
of plenty who have.

I had one that went bang literly.
But the chargers supplied with my iuDevices have all worked OK and never
caused a problem.

Although I did just get this 'report' at the top of a google spreadsheet
I've had open all day.

" This webpage was reloaded because it was using significant energy."

If it said memory or RAM or something but energy ?
Maybe I should invest in a windmill.
Or in this lab something that turns sound into power/energy, we've hit
91db today.



It does make you wonder how much money the maker saves by selling
something that doesn't deliver the current it claims. Must be tiny.

Maybe it's not the components as they are pretty standard surface mount

Its more complicated than that. Look at Big Clive's strip downs sometime.

Yes I know it is.


I think it's the board & contruction quality and insulation etc.. not
being up to it.

Not always.

It usually is that's what happened to samsung batteries.


When you see a charger for £1.99 and sometimes 99p I really wonder about
them.

The ones apple flogs cost a hell of a lot more than £1.99

yes I know maybe that's why my aplpe ones are still working and teh cheapo I have went bang sparks were seen at the USB port and teh USB plub had blackened slightly.
