Tier: budget. One of the easiest beginner picks in this category.
There's nothing outdoorsy about the INIU. It's a slim, inexpensive 10,000 mAh bank. On a budget, that's often all a weekend backpacker needs.
Specs (per the listing, model BI-B1)
- Capacity: 10,000 mAh
- Weight: about 7 oz
- Size: 5.2 x 2.7 x 0.5 in
- Ports: one USB-C (in and out) and two USB-A outputs
- Extras: a small flashlight, a paw-print charge indicator, and a travel pouch
Pros
- Light and thin for a 10,000 mAh bank
- The USB-C port works both ways, so one cable can charge the bank and your phone
Cons
- Not weather-sealed. Keep it in a zip bag.
- Ordinary consumer build. It's not designed for the cold or rough handling the way outdoor-focused banks are.
The math
10,000 mAh at 3.7 V is 37 Wh, the same as the BioLite Charge 40 PD. The buying guide explains why that delivers about 1.5–2 modern phone charges, not the bigger numbers some ads suggest.
