SlimCharge vs. a power bank
| Typical power bank | SlimCharge | |
|---|---|---|
| Extra item to carry | Yes | No, it is your case |
| Weight | 200 g or more | About 31–55 g |
| Needs a socket to refill | Always | Sunlight works |
| Forget it at home? | Often | It is on your phone |
SlimCharge is a slim backup that tops up your phone and extends your day. It does not replace a large power bank for heavy, all-day use, and charging speed depends on sunlight. All specifications are development targets.
