Nice Power batteries are high quality, long lasting and beautifully packaged lithium batteries. They are ideal for home CCTV systems such as Blink or for your photographic / high drain devices. Just because they are designed to be used with high drain devices that does not mean they are not equally as useful with low drain devices such as electric toothbrushes, shavers, mouses or keyboards. Users will quickly see the difference with your devices lasting up to 10 times longer using the power of Lithium.
