Today I am going to introduce yet another interesting USB accessory following my story on the USB cup warmer. Both USB warmer and this battery aren't new products. But again, they are not really well-known locally.
USB battery can actually be more useful in situations such as when your wireless mouse ran out of juice. It also come in many shape and sizes for various products.
I actually saw this product on magazine some time ago. But it is only last week that I saw it on sale at Sim Lim Square (Best Bargain). However, only the AA batteries are on sale there. The price tag is S$14.90 (Do not quote me this price and location is only for reference!).
