Canon Powershot Sd1100 Is Charger
Is this compatible with the Canon PowerShot SD1100 IS?

I lost my Camera Charger and this link said was for it. It looks completely different from the original charger I received with the Camera. Is it going to work?

Canon Powershot Sd1100 Is Charger

Can I charge my canon powershot SD1100 IS on my computer or does it have to have the wall charger?

Your camera came with a NB-4L Li-ion battery and battery charger .. use it and it only

If you try charging your battery with any other charger, you risk overheating the battery, thus shortening the batteries life .. in extreme situations, the battery can catch on fire or even explode.
