Now these may look like normal AA batteries, but the magic is revealed when you pop the top open to reveal a USB plug. Instead of needing a bulky recharger you plug them into any powered USB port and they?re fully recharged in only 5 hours. Just think, you have so many potential chargers in your home. From PCs and laptops to keyboards, hubs, games consuls, even some monitors.
