Question for Electrical Engineers!

[GTaudiophile]

I have two cell phones. One was bought in Greece last summer. It's a Sony Ericsson. The charging adapter for it is euro-spec with round prongs. The specs are: INPUT: 100-240V, 150mA, 50-60Hz OUTPUT: 5.1V, 450mA.

My main phone is also a Sony Ericsson T610 with a very similar US-spec charging adapter. The specs are: INPUT: 100-240VAC, 150mA 50-60Hz OUTPUT 4.9V 450mA.

Can I use the chargers inter-changeably? Meaning, use the euro-spec charger on my T610 or use the US-spec charger on the older Sony Ericsson?

Certainly.

±0.2V shouldn't be any big deal.

<-- Not an EE.

I vote yes

The plan is to take both phones and the euro-spec charger with me to Germany on business on Saturday. I have international roaming with TMO on my T610, so people from the US can call me. But I'll buy a new SIM card for the other SE and use it for intra-Germany communication.

Yup, should work!

Just make sure it's not like 5.1VAC and 4.9VDC or something crazy.. lol..

0.2V is pretty insignificant to something like a charging circuit, in my opinion.

Even a CPU can handle ±0.2V... well, usually. Regardless, it shouldn't be that sensitive.

I plugged the euro-adapter into the wall using a euro-to-us add-on adapter, and it successfully charges my T610.

Should work. Besides, you tried it and it didn't fry it... right? 🙂

Sony Ericsson most likely intended for the chargers to be switchable between its products, like Nokia does. The difference in 0.2V could be simply engineer-added-"slack" or whatever. Not that big a deal.

 

[Bassyhead]

should be fine

I say it should work fine. What's 0.2V gonna do? 🙂
