Wirecutter's top power bank for phones, thanks to built-in USB-C and Lightning cables and pass-through charging. Its writer's unit has held up for two years of near-daily use. But about 1 in 4 Amazon ratings are 1 or 2 stars, with owners reporting units that stop charging after months.
Top complaints
- Stops charging or dies after a few months
Amazon's review summary says some owners find it never charges fully or stops working, and several say it broke after 6 months. Low-star Walmart reviews describe a unit that won't recharge after one use, one that 'refuses to charge' about 2.5 months in, and one that only works briefly after sitting.
- Modest charging power
Wirecutter measured 18 W out and 19 W in, with 24 W total across two devices. Some Amazon owners say it barely charges iPhones.
- Pricey and heavy for 10K
Wirecutter calls it on the pricier side ($55 at the time) with no accessories. It weighs 8.4 oz, more than the INIU and Scosche alternatives. Amazon owners are split on value.
What owners love
- Two built-in cables
Built-in USB-C and Lightning cables slide in and out of their holsters easily (Wirecutter). Amazon owners appreciate the built-in cords.
- Pass-through charging
Wirecutter measured up to 15 W of pass-through while the bank recharges, which it calls convenient but somewhat rare.
