We never complain about having a heavy key-set. So what’s the difference if you add another keyring? How about you add another keyring that actually has multiple functions for your smartphone – the WonderCube (which is currently on Indiegogo) is a cubic inch keyring with 8-in-1 functions.
The features include:
- A built-in cable
- Power boost
- A phone stand
- OTG USB
- Syncs your devices
- An emergency charger
- Flash memory
- A built-in LED torch
