Anker PowerCore Slim 10000 (A1229) Review
This is a plain, slim 10,000 mAh bank with a long, good owner record. It suits weekend trips where it can refill overnight.
The verdictA dependable, cheap 10,000 mAh bank with about two phone charges in it. Slow to refill, so plug it in overnight.
The listing gives the PowerCore Slim 10000 as 240 g and 153 x 72 x 15.5 mm, a flat slab that slides into a frame bag. It charges devices at up to 15 W from its USB-C port, with a USB-A output as well, and refills through USB-C or Micro-USB. A trickle mode suits low-draw devices such as earbuds or a head unit.
Anker's own listing figure is about two charges of an iPhone 15, and it takes about 5 hours 10 minutes to refill. That refill time is the trade. It will not top up meaningfully over a 40 minute cafe stop, so plan to refill it overnight from a wall socket.
The owner record is the reason to choose it. Owners on Amazon US gave it 4.5 stars from 7,653 ratings in October, with 8 percent at one or two stars, and Amazon's review summary counts most reliability mentions as positive. Charging speed and weight draw the complaints.
Anker's listing does not claim pass-through charging, and the warranty is 18 months. Anker's own product page describes an older revision of this model with slightly different dimensions, so the figures above follow the Amazon listing this link opens. Like every lithium bank, it flies in the cabin only, and it should not be charged below freezing.
