Probably the world's smallest V-Mount battery. And it's not just small - its powerful. With 50Wh up to 8 Amps working current you can get a lot of power out of this little buddy. With one D-Tap output and lots of other USB outputs, so you're never running out of possibilities to power your equipment.
The best thing about it is the regulated USB-C output, that can charge your MacBook or any other USB-C compatible device on the go.
At the moment there are two other capacities available - a 98 Watthours and a 150 Watthours battery, called NANO TWO and NANO THREE.
A LCD shows you the remaining capacity and voltage as well as the voltage of USB and USB-C ports. These sockets are protected from dust and moisture by a rubber lid.
There are some dedicated accessories around, like different plates - of course in the compact design of the NANO battery.
