Sure it will.
Doug , I said I don't 'know' of any 'good' AC /DC peak chargers
out there. There's quite a number on the market. And most of
these won't charger LiPos.
A good peak charger with a good power supply built in is expensive ,
heavier and bulkier and , in most cases us rc flyers don't need AC
input anyway.
I suppose I should have been more specific when I said :
| " You need a filtered power supply that will deliver a steady

I was referring to AC chargers and I meant to type
" ac chargers " ......my typing sucks , but since the topic was
AC/DC chargers I think most people would grasp the meaning of
that sentence even with the missing word.
example, that computer you're using runs internally
on DC, and if it's not steady and well filtered, your computer doesn't
go. And if you have a modern cpu, you may even find that the amps of
DC current drawn by your cpu is even more than drawn by your electric
plane! (But the voltage is usually a lot lower.)
Yes it does. . This AMD chip I'm running consumes about 80-90
watts at 1.4 volts , at idle , according to AMD.
Right , I don't have an airplane now now that pulls in the 60-65 amp
range.
You are correct in that most peak chargers run on 12 volts, but
there's no reason why a power supply can't be made. But it would add
cost and size to the charger, and many of our fast chargers are used
at the field anyways so 12 volt DC power is more convenient than 110
volt AC power.
(And indeed, a PC power supply does work nicely as a power supply for
a R/C charger.
I have two power supplies for my chargers that are modified PC
power supplies. out of some old computers I had in the shop.
Work great.
The modification isn't even particularly tricky.)
Hardly any modifications on an AT power supply , and very
little on an ATX . The hardest part is putting in some kind
of plug or connection to hook your charger to.
The only time that converting 110 volts AC to 12 volts DC is really
difficult is when it's a power supply meant for radio use (like a ham
radio) -- switching power supplies make a good amount of RF noise, and
that can interfere with a radio. But even this can be taken care of
-- it just makes it all bigger and cost more.
Don't know anything about ham radios or what type of power
supplies they require .
(And as a side note, my Triton by itself makes all sorts of RF noise
when it's working. It's probably not anywhere near enough to crash a
plane while you're charging the batteries of another at the field, but
it can certainly drown out any weak signals on the radio in your car
if you're charging in it. (Note that most broadcast FM stations do
not qualify as weak ...))
