ReVolt : USB power your battery devices
We have developed a practical way replace your batteries, for good.
It's a simple swap, you take out your device's batteries (either AAA, AA, C or D), put in our ReVolt bridge cable and you are good to go, our USB cable will now power your item.
With ReVolt, you'll never need to put batteries in there again. Now you can power it whichever way suits you - from a wall phone charger, a USB port on your laptop, a USB powerbank, a USB wall plug, or even from a USB solar cell.
