Go Puck Wearable Power
Charging is done with the micro port with the very beefy usb charger cable which is included. The same cable is used to charge your devices. Just plug them in. A fully charged Go Puck 3x will charge a small smartphone twice. The larger Go Puck 5x will charge a small phone around 5 times.
If you don't care for the classic white, choose from one of the skins to make it truly your own..
I keep mine charged and carry it in my purse. The mount is very convenient to attach your camera (in it's case) to the top of the Go Puck to keep the charger near by and attached.
For added convenience you can get the zippered carry bag for $19.99. The carrying case is zippered and has a clip to attach to a lanyard or hook.
You can also order individual action mounts. A second mount allows you to mount the Go Puck to both your camera and a tripod or other camera mount that uses a threaded pin. They are $19.99 as well.
In the years that I've had this, it has become my MUST HAVE in my bag. I keep it charged and in my purse while wandering, and in the little carry bag around my neck at all times when I'm at trade shows or media events. I've even shared power with strangers in lobbies and on planes. One of my all time favorite items.
