It’s fair to say that we have all been through such situations, although it may be different devices that we were using at the time.
So here comes the Continuance Battery concept designed by Haimo Bao, Hailong Piao, Yuancheng Liu and Xiameng Hu. Not only is this battery rechargeable, but it is also environment-friendly.
The icing on the cake is that it can be charged via a USB port and can power any device that needs AA batteries.
Clearly, the Continuance battery will find use in many homes, offices and even cars. But it will have to compete with other types of rechargeable batteries. But those batteries need their own chargers; this only adds to weight when travelling.
Besides, the more things you have to remember to pack, the greater the risk that you might forget to pack one of them on your way to or from your destination.
Some questions also exist about the rate at which the Continuance battery will discharge when it is used to charge an iPod or similar device.
The USB port is built into the battery’s body. This raises questions about its capacity, although with advances in material science, this concern may well be unfounded.
But what is undeniable that you will need one USB cable per battery to charge it. So if you need to operate a device that runs on say, 3 AA batteries, you’d better be prepared for a longish wait till all 3 batteries are fully charged.
