Overview
A 2-pack of slim 10,000mAh power banks with bidirectional USB-C plus dual USB-A ports, built to charge up to three devices at once. Each bank weighs 7.68 oz and carries a flight-safe 37Wh rating.
The USB-C port does double duty here, both recharging the bank and outputting power to a phone or tablet, which simplifies which cable to pack. At 5.5 x 2.6 x 0.6 inches each, the pair is meant to be split between two people or kept one at home and one in a bag, and the 37Wh rating stays within typical airline carry-on limits.

What buyers say
From Amazon customer reviews.
Reviewers who bought these for travel and camping report they hold a charge for days and recover quickly when plugged back in, with several praising the USB-C convenience and pocket-friendly size, including one buyer who used it through a power outage to keep phones and borrowed fans running. A couple of buyers called the charging speed slow, including one who said the bank itself took several days to fill, and another noted the capacity does not match a bulkier bank, though having two on hand balances that out.
Strengths and trade-offs
Drawn from this product's published specifications.
- Charges up to 3 devices at once
- USB-C handles both charging in and out
- Slim, pocket-sized at 7.68 oz each
- 2-pack covers home and travel or two users
- Charging speed is modest rather than fast
- Not a heavy-duty bank for repeated full recharges
- Lightning cable not included
Performance notes
Three outputs, two USB-A plus USB-C, and two inputs let it charge multiple devices while itself recharging, and the bidirectional USB-C design means one cable can serve both directions. Reviewers who used it for camping and travel report it holding charge over several days between top-ups.
