Charging my Cell Phone

[[email protected]]

Hi Guys & Gals;

I puchased a cell phone, a Sony Ericsson Z200, and I decided to only
charge it by solar power (nice in theory). I had my phone for a month
and it pooped out, the battery had a great charge, but the phone had
no life at all. Totally fried.

I exchanged the phone for another one, brought it home, ran down the
battery (as suggested) and this time I charged it from my battery bank
using the correct 12 volt plug instead of using the wall charger and
my (cheepo) inverter.

Well, I once again have a fried phone, please help, what should I do?
Can a cell phone be safely charged with a square wave inverter? Is
there anything that I should know before I buy and charge another one?

Some of this is not clear. Did you run the charger off the 12V battery or an
inverter?

Many chargers control the current / voltage by chopping the quantity down by
time slicing the on off ratio. This depends on a fairly stable input power.
If you feed a MSW inverter into a chopper circuit trouble may result as the
frequencies can interfere with each other' s operation.

Hi again Guys & Gals;

Thanks for the advice, by the way before reading your responces I
foolishly tried charging my brand new Siemens CF62. Until I get a sine
wave inverter I guess that I will charge my phone (as soon as I
exchange it in the morning, oops) off the grid, I am sure having some
fun with all this.

On a related note, I have a small microwave which uses significantly
less energy than it should (200-400 watts as opposed to the 800 it
should need), it also barely heets at all. Is this becouse of my
inverter again?

Confused and having fun

Yessum. You're lucky it works at all, in my experience. Microwaves
pretty much need sinewave inverters.

...have to respond here. At an isolated cabin I have a Trace 3624
inverter,
which is an MSW type. The broadcast band interference is fierce because of
the upper harmonics.
BUT... I've been running a microwave, TV, DVD, tape player plus the
usual
lights for about five years on it, trouble free. Even used a DeWalt
rechargeable
drill with charger to build a large shed (garage package) that has almost no
nails.
I used screws. (Bad elbow on my hammering arm). It also runs a water pump
that (I believe) has an induction motor, with very little heating.
The only problem I had was when I tried some small capacitors on the
output to kill the RF harmonics... I think that's what shot the output board
on the inverter. Replaced that.
I guess I coulda been lucky... or maybe it's the inverter capacity.

I also have a 3624 and have had for many years. They are very rugged
and noisy. So when trace came out with the sw4024, i got one of the
first production usits, just to get rid of the RF noise. Still have both
and they are still running many years later.
Yep, don't mess around with the output of the 3624, or you'll likely
blow the PowerFET Bridge. No an hard fix, but a bit expensive.......

Bruce, I've been mulling over going to the SW 4024 and keeping the
DR3624 as backup. Is it really a LOT cleaner in the broadcast band?

The FETs sounded like a string of firecrackers. $600 Cdn for
a new board.

I found a "significant" difference in the amount of locally generated
noise when I upgraded to the 4024. If I had it all to do over however I
would go with a 4048 instead of the 4024, and keep all my batteries in
one single string. No difference noise wise, but it drops the current on
the battery cables by half. Same money either way.

Thanks, Bruce.
Worth some thought.
