10000mAh Portable Charger Stylish Compact
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.
Listing capacity in Wh rather than MJ is fine, but many batteries are rated in amp-hours which isn't very helpful unless you also know the voltage. This is particularly annoying when it comes to "smart batteries" such as this USB power pack[0] where you have specs listing "10000 mAh" and "5 volts", but the actual capacity is around 37 Wh because they measured amp-hours at the internal battery and the battery voltage isn't exposed to the user. (Yes, the product description halfway down the page does say "10000mAh/3.7V" in small print if you know to go looking for it, but this isn't noted anywhere in the title or the "About this item" section at the top.)
