Where can I get portable, rechargeable USB batteries?
I saw these batteries that had a USB port on the end of them, you can charge them with your computer with the USB port and then take them with you and charge things when you are away from a power source, for example, your phone.
What is the name for this and where can I find one?
Like another said, use a search engine. I too, found many sources. The most recent I researched was on Ebay. There is a problem with these devices that you should be aware of and consider if you plan on buying these. A typical Nickle-metalhydride (NiMH) rechargeable AA cell has a capacity of 2000 MAh or more. I have a set I am using at the moment in a camera which has 2500 MAh capacity. They actually contain more power than equivalent AA alkaline cells. The drawback to rechargeables is the lower terminal voltage at 1.25 volts as opposed to a typical alkaline cell with 1.55 volts. The lower voltage DOES make a difference in SOME applications, such as my MP3 player. I get about 30 hours from a AA alkaline cell, but only about 20 hours from a NiMH cell. A NiMH cell costs about 3 times the same size alkaline cell, but after the 4th recharge, it has paid for itself. After a few more recharges and the charger has paid for itself as well. The USB AA size cells I saw only had 750 MAh capacity, about 1/3rd of the cells I have. THAT would mean that much less run time in my MP3 player. And then, how many USB ports do you ave available while on the road on a typical computer? My Laptop only has 1, and my desktop has 2. Without a powered hub, I’m not going to be charging very many USB cells, am I? And then there is the time it will take to recharge. The ads I saw say it takes several hours to fully recharge but you can get SOME use out of 15 minutes or so. A typical recharge for my 2500 MAh cells is overnight, or about 12 hours. My wall charger can charge 1 to 4 cells. All this says is that these USB cells are simply NOT cost-effective. You would be much better off investing in a set of 2500 MAh AA cells and a charger and then carry spare cells than use USB cells. For me, the dealbreaker is the capacity being about 1/3rd and yet the cost per cell is about the same. What you are paying for is the convenience of having a built in charger so it can recharge from a USB port, but realistically, wouldn’t you rather have 3x the number of hours of use before a recharge is necessary and carry a spare set of than have the convenience of a recharge circuit built in?
