I think we might have hit peak “portable charger”. Not content with building them into everything from wallets and handbags to belts and hand luggage, now you can have a portable charger in a make-up compact. Hidden right underneath your blusher is a USB port that will hook up to your smartphone or other USB- chargeable device, and give you some emergency juice. It’s got a 4200mAh battery, and some LED lights that will blink to let you know how much power you have left. It’s also got some blusher and a mirror in there, but it’s a little on the chunky side to masquerade as a regular part of your makeup case.
