The best power bank for iPhone 7 Plus is a 10,000mAh model, which gives about two full charges, plus an MFi-certified USB-C to Lightning cable. The iPhone 7 Plus does not support the fast charging that Apple added with the iPhone 8, so you do not need an expensive 45W bank. Any bank with a USB-C port and a decent cable will do, and a bigger one only matters if you want more charges. We compared specs, tested-by-others results and real owner feedback. Ratings were read on Amazon on 21 October 2026.

Quick answer
- Best low price: Anker 10,000mAh PowerIQ. A simple two-charge bank from a known brand.
- Best 10,000mAh: INIU 10,000mAh 45W. Light at 8.4 oz, with a three-year warranty.
- Most charges: INIU Smallest 20,000mAh 22.5W. About four iPhone 7 Plus charges.
- The cable you need: Anker USB-C to Lightning cable, 6 ft. MFi-certified, 4.7 stars from about 25,000 ratings.
What to check before you buy
Two things matter when you choose a bank. First, you need a Lightning cable: a bank with a USB-C port works with a USB-C to Lightning cable. Second, you do not need more than about 12W, so a 45W bank will not charge your phone any faster.
How many charges will you get?
- 5,000mAh: about 12Wh usable, roughly 1 iPhone 7 Plus charge.
- 10,000mAh: about 24Wh usable, roughly 2 charges.
- 20,000mAh: about 48Wh usable, roughly 4 charges.
These are estimates at 65 percent efficiency for a new battery. An older iPhone 7 Plus with a worn battery will need more charges per full recharge.
Power banks and cable for iPhone 7 Plus reviewed
Each pick below was in stock with 4.0 stars or better and at least 200 ratings when we checked. We compared specs, tested-by-others results and real owner feedback; we did not run our own lab tests.

4. Anker USB-C to Lightning Cable, 6 ft: The cable you need
Apple’s Lightning cables need to be MFi-certified to work reliably. This 6-foot Anker cable is MFi-certified, weighs 2.22 oz and holds 4.7 stars from about 25,058 ratings. We could not find a warranty length on the listing, so we scored that category 2.
Score: 4.2 out of 5 (portability 5, output 5, warranty 2, owner rating 4.7)
Pros
- MFi-certified
- 6 ft is long enough to use while charging

Cons
- Warranty length not stated on the listing
What owners say: 4.7 stars from about 25,058 ratings.
Buy it if Your bank has a USB-C port and you need a Lightning cable. Skip it if Your bank has a USB-A port; you need a USB-A to Lightning cable instead.

Why a bigger bank is not always better
A larger bank only adds charges. It does not make an iPhone 7 Plus charge faster. If you carry the phone in a pocket, the 10,000mAh banks are easier to live with.
How we score and choose
We chose three power banks and a cable that are in stock on Amazon with at least 4.0 stars and 200 or more ratings.
How we score
Each score is the average of four numbers out of 5. The rules are:
- Portability: weight from the listing. Under 15 oz = 5.
- Output: an iPhone 7 Plus can only use about 12W, so a confirmed 12W or more = 5; output not confirmed = 3.
- Warranty: 36 months or more = 5; 24 months = 4; 18 months = 3; 12 months or not stated = 2.
- Owner rating: the Amazon star rating itself.
| Product | Portability | Output | Warranty | Owner rating | Score out of 5 |
|---|---|---|---|---|---|
| INIU 10,000mAh 45W | 5 | 5 | 5 | 4.5 | 4.9 |
| INIU Smallest 20,000mAh | 5 | 5 | 5 | 4.6 | 4.9 |
| Anker USB-C to Lightning cable | 5 | 5 | 2 | 4.7 | 4.2 |
| Anker 10,000mAh PowerIQ | 5 | 3 | 3 | 4.5 | 3.9 |
