Overview
A 5,000mAh Anker power bank with a foldable USB-C connector built into the body, so it plugs straight into a phone without a separate cable, and outputs up to 22.5W with PowerIQ 3.0 fast charging.
The built-in connector is the point of the Nano line: fold it out, plug it into the phone's USB-C port, and there is no cable to lose or tangle. Anker still includes a 2 ft USB-C to USB-C cable in the box for recharging the bank itself or for devices that need one. At 5,000mAh it is sized for a partial top-up rather than multiple full charges, matching its pocket-sized form factor.
- Foldable built-in USB-C connector
- 22.5W output with PowerIQ 3.0
- 5,000mAh capacity
- Includes USB-C to USB-C cable and 24-month warranty
Who it's for
People who want one emergency charge for a phone without carrying a separate cable, useful for commuting, travel days, or as backup power kept in a bag.
Strengths and trade-offs
Drawn from this product's published specifications.
- Built-in foldable USB-C connector, no separate cable needed
- 22.5W with PowerIQ 3.0 for fast charging on supported phones
- 5,000mAh in a pocket-sized body
- 24-month warranty from Anker
- 5,000mAh covers roughly one partial phone charge, not multiple
- Actual speed depends on the connected phone's own charging limit
Performance notes
PowerIQ 3.0 negotiates the fastest safe charging speed the connected phone supports up to 22.5W, so charge speed in practice depends on the phone's own USB-C fast charging ceiling rather than the bank alone. The foldable connector tucks flat against the body when not in use, which keeps it pocket-sized instead of adding a permanent cable that snags on other items in a bag.
