The Cloud V Powerbank is a 5600mah battery backup and charger. The kit comes with the Powerbank, a USB to micro USB cable and three adapter heads. Charge the Powerbank by plugging in the micro USB and connecting to a wall charger. A LED light will show the progress. To charge a device, simply connect the Powerbank charger to your device's USB port. It is compatable with vaporizers, phones, tablets and more. each head easily snaps into the micro USB for your device.
I like the Powerbank and the several charging options. It's basically the same shape and feel as an Apple mouse, but slightly heavier. My only con is that it didn't come with instructions, but it was pretty easy to figure out. The Powerbank currently costs around $20 and seems like a great companion to any vaping kit or to take along on a trip.
Cloud V also offers a wide variety of vaporizers and accessories.
