Buyer feedback ↓Anker’s A1259 Nano power bank puts a short USB-C cable on the body. It is a fixed loop cable, not the retractable cable used on a different Nano model.

THE QUICK TAKE
Is it right for you?
Choose A1259 if forgetting a cable is what stops you using a power bank. The built-in USB-C lead is ready for a compatible phone, and the display makes the remaining charge easier to judge than a few small lights.
Choose a simpler bank with replaceable cables if you want every cable to be easy to replace. The attached lead is part of this unit. Its capacity is not a guarantee of a fixed number of full phone charges, and charging several devices divides the output.

02 / AMAZON REVIEWS
The buyers’ view.
Owners reviewing the black version appreciate its compact size, useful display and cable loop for carrying. One particularly likes having the charging cable attached rather than remembering a separate lead.
Charging experiences are mixed: some describe fast charging, while another found phone charging slower than hoped and reported that multiple wall chargers became very hot while refilling the bank. That owner was considering a return or replacement.

Fast Portable 30 Watt Charging: Anker Nano Power Bank with Built in USB C Cable Review
See the built-in cable and the extra sockets on the fixed-cable Nano model. This is not the retractable-cable Nano.

The test confirmed the rated single-port output and appreciated the display. A useful limitation was the lack of simultaneous device charging while the power bank itself was being recharged.
Anker separates maximum single-port performance from the reduced shared total. The built-in USB-C cable can also be used for recharging the power bank with a suitable charger.
