INIU Carry P50-E1

36Wh and 45W with a built-in lanyard cable — the pocketable everyday pick. At $32.99, INIU's 2024 model sits among the cheapest we cover — the power Banks we compare run from $25.99 to $229.99. It scores 7.7/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.

Its strongest showing is Portability at 9.0/10 — weight and size relative to the capacity you get. The weakest is Capacity at 6.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.

Worth knowing before you buy: no confirmed standalone Amazon listing could be matched to this exact model number — INIU runs several near-identical 45W 10,000mAh SKUs, so verify the model before buying; and output drops to 15W shared when several devices are attached. Every specification on this page comes from INIU's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
