Why this deal matters

Portable chargers seem to be a dime a dozen these days, but they often add weight and bulk to your overstuffed commute bag. Finding one that’s light, powerful and compact is always a bonus, but finding one that’s just that and only $16 to boot — $4 off the regular price — is even better.
