It is very inconvenient for the blind to check the battery power. They are unable to identify the consumption of the battery, insufficient or even run out. This power measurement is specially designed for the blind in daily use to solve this problem. The power measurement is composed of three parts: top lids, bottom lid and sliding main body. The top and the bottom lids are used to connected with the anode and cathode of the battery; the sliding main body can be adjusted the length to match the size of the battery. The Braille on the top lid will remind the bind of the consumption of the battery power.
