doubt all you want. nearly all chargers are 1a or greater, so they
*must* have some sort of firmware, even if it's a state machine.
only very old chargers are 500ma, or cheap shit which wouldn't be
there aren't other tricks. sourcing more than 500ma requires conforming
to the charging spec.
There isn't for 1A devices. There is for 2A devices: they must
comply with fast/quick charging:
For non-compliant devices the charger will give 1A max.
Which, on second thought, would imply that Pamela could charge
her digital dictator from a 2A charger.
Either your phone doesn't comply with the fast/quick charge
standard, or you have to enable fast/quick charging. Check
if your phone is on the compliant device list:
Let's face it, pamela isn't going to accept anything less than a
guarantee signed in blood by the person who designed the recorder, they
they will personally buy her a new one if a 2A charger kills it.
Got to be as ultra-cautious as you say. I've already damaged two
?100+ Olympus voice recorders most probably by the way they were
charged through a USB port.
The advice I've been getting in this discussion veered one way and
then another. In one inspired moment afew days ago, I was
persuaded by an interesting post (moments before someone
immediately contradicted it) to just try the mains charger on my
recorder. I'm happy to report that all seems well.
Thanks to all who helped.
I would have dismissed the assembled throng in this thread but you
guys seem to be having such a good time discussing and arguing
about it that I don't have the heart to spoil the fun. Carry on
fellas. Don't mind me. :-)
USB is largely for consumer devices, consumers see USB plug, see USB
socket and (rightly) think that belongs in there; it's up to the
designers to ensure that it works, or that at worst it does no harm, USB
wouldn't have lasted long if it was otherwise.
Now with USB type C, it's still immature and there are horror stories,
e.g. where you can plug a device to a charger, they negotiate a higher
voltage than the standard 5V, you unplug the first device, plug in
another device and the new device is not prepared for a higher voltage
but the charger doesn't immediately drop back to 5V when it sees the
My Motorola phone came with ONLY a fast charger. But I seldom need a
fast charger. I charge it overnight with a standard .5A charger
and it's topped up fine in the morning. So I think you can probably use
most any standard charger if you want to. Give it a try.
Of course, I use a standard charger. In fact, one with eight mouths so
that I charge all my gadgets while I sleep, with less cables than if
using their original chargers.
The charger on the box was also standard, with two sockets. But it said
that plugging two devices they would charge at half speed... And the
brochure said the fast charger had to be bought separately.
Apparently Motorola does not want to give us all a fast charger. Nor
that I need it, but I was curious to see/try it.
Perhaps they only come with the premium models.
(Droid Turbo 2 @ US$630).
My fast charger is kind of a pain to use. The relatively short cable
is hard wired to the charger. But very handy when needed. It does bring
the phone to full charge quickly and (surprising to me) doesn't get the
phone all that hot.
Occasionally I need the fast charger. If I'm not in a hurry
I plug it into a USB port of one of my PC's. Both of them
have a couple of USB ports that are powered even if the PC
is powered off. A quick test shows that they can deliver
500 mA in that state. Might be interesting for Pamela too.
