Full-capacity power banks are the wrong tool if you're carrying a purse. You need something under 130g that disappears into a side pocket, not a brick that unbalances your bag. These four prioritize real portability: under 130g, palm-sized, and actually fast enough to get you from 15% to 60% before your next meeting.
A full-capacity power bank (20,000mAh+) charges your phone 4–5 times but weighs 400–500g. A purse-size bank (4,800–5,000mAh) charges your phone once and weighs under 130g. These are not competitors, they solve different problems. The purse bank is daily insurance against a dead phone. It's not camping gear, it's not a flight kit. It's the thing in your bag that means 15% battery is never a crisis.
| Model | Capacity | Max Wattage | Weight | Built-in Cable | Price |
|---|---|---|---|---|---|
| Anker Nano 5000mAh | 5,000mAh | 22.5W PPS | 96.4g | No | ~$27 |
| Baseus PicoGo 5000mAh | 5,000mAh | 20W PD | ~100g | USB-C built-in | ~$35 |
| iWALK LinkPod 4 | 4,800mAh | 13W | ~130g | Lightning + USB-C | ~$20 |
| Sethruki 5000mAh | 5,000mAh | 12W | ~95g | No | ~$16 |
22.5W PPS fast charge means iPhone 14 goes from 0% to ~60% in 30 minutes. 96g means it weighs less than a deck of cards. PPS charging protocol works with modern iPhones and Android flagships. Anker's quality control on this line is consistent, you're not gambling on whether it charges at rated speed. This is the benchmark for the category at this price.
The built-in USB-C cable is the differentiator, nothing to forget, nothing to lose. Lipstick-sized form factor fits in a makeup pouch. 20W PD is real fast charge. The MagSafe-compatible version sticks magnetically to iPhone 12+ which eliminates fumbling with cables entirely. If you've ever searched for a charging cable buried in your bag, this solves that permanently.
The iWALK LinkPod 4 has built-in Lightning and USB-C connectors that plug directly into your phone, no cable required at all. For households with mixed iPhone and Android users, this is uniquely useful. Slower at 13W, but the zero-cable setup means you can hand it to anyone and have it work immediately regardless of which port they have. Best option if you share your charger.
At $16, the Sethruki is the right pick if you want the smallest possible thing that charges a phone in an emergency. The ultra-thin flat design takes up almost no space in any bag. 12W output is slower than the Anker but gets the job done. No fast charge, no built-in cable, no MagSafe, just a small, light, cheap power bank that works when the alternative is a dead phone.
