$2 universal battery charger
I just got a few of these universal battery chargers for $2.01 including shipping (no taxes) that draw power from a USB connector. So far, it looks great and I can charge most of my lithium ion batteries. My new Canon 500D Rebel T1i has a battery with some vertical narrow strips and that unfortunately won’t work with this charger without some very creative pin bending on the charger which I can’t recommend.
While this isn’t something you would want to use as a routing way to charge your battery, having this little device in your bag on the road is a life saver when you forget one of your normal chargers. Of course if you forget your laptop charger or 110-220 volt AC to USB adapter, you’re out of luck.
Deal Extreme also has another charger that’s $2.60 which is rated pretty well and they offer $0.01 shipping all over the world. I pay them via PayPal and it’s all very convenient. My experience is that it takes anywhere from 2 to 5 weeks to get a product in the mail box in a plain brown envelop. But for the price and virtually free shipping, it’s worth the wait. They’ve got lots of other useful things most of which are very good deals. Some of the more expensive items don’t seem like good deals to me so make sure you do some price research before you buy.
