Info On Sl-c3000 World Voltage Ac Adapter Specs

Hello,

I have recentlly purchased a new SL-3000 and I think this one is great, I had SL-5500 beforehand I think that 640x480 resolution is really worth the price

Unfortunately my wife put the AC Adapter charger directly to 220 Volts but it was not a World Adapter but was for US 110 Volts, so blew off

I was planning to use my previuous converter [220=>110 Volts] that I used for charging my previous SL-5500 but now the 110 V US Adapter is not working

I am planning to use an external adapter and searched this forum for the specs. As far as I can see I just need an adapter that has DC 5.0 V and 1.0 A. Unfortunately I could only find an adaptor for 5.0 V but 0.5 A. I am by no means an electronics expert so I don't know whether this one will damage my new SL-3000 or not. Can someone please tell me if it is OK to use 5.0 V / 0.5 A for charging my SL-3000 ?

I had searched these pages/forum on on http://www.oesf.org/index.php?title=C3000_General_Info
I saw that :
* Battery & Power
* 1800 mAH, external charger
* warning, no reverse polarity protection so be VERY careful if using a non-standard power supply

but on my broken charger charger it reads 1.0 A not 1.8000 mAH so I am a bit confused.

Also the following information written there has left me deeply worried :
warning, no reverse polarity protection so be VERY careful if using a non-standard power supply

As I said, I don't know what is a "reverse polarity protections" and I am further worried for finding a suitable charger that will be ok for my SL-3000

Could someone with electronics background please tell me exactly which spesi fications are neeed for charging my SL-3000 from 220 Volts ?

- Volts ?
- Ampers ?
- Watts ? [I do not know if watts is relevant here or not]


Or can I use my previous SL-5500's charger for charging my new SL-3000 temporarily for a few times till I find a new charger according to specs ?

Any directions/help would greatly be appreciated
Thanks in advance
