Are USB chargers interchangeable among cell phones, PDAs... despite differences in amperage?

Question

I have a pocket PC with a USB charger that connects to the 220v wall plug. It gives 5 volts and 1 amp.

Then my brother lost his Motorola and gave me his charger. It's also USB, also 5 volts, but only 0.55 amps.

It would be convenient if I could have one more in use for the PDA. But... shall I try it? Is it safe?

Thanks in advance!

Answer 1

Theoretically, yes. In recharging batteries, it is the voltage, not the amps, that counts.

But you should be aware that:

(1) You would void your warrantee if something goes wrong,

(2) Some of those chargers (actually the important thing is the transformer which is attached to the wall) may actually deliver a voltage that is too high which could fry your PDA.

(3) Some electronic equipment now has smart battery technology (which I doubt your PDA has) which prevent it from working.

I personally would do it, but you have to be aware of the downside risk.

Answer 2

it rather is significant to me. It hyperlinks me to the the place-abouts of my young little ones. i'm a worrier, and if i do no longer understand the place my little ones are .. I hardship, lots. as quickly as the little ones have left living house, i do no longer think of i will have lots use for it. :)
