What to know before buying
Listing details to confirm
Listing details are inconsistent or unconfirmed: the title and feature copy claim 30W, while the A+ specification lists 24W maximum total wattage. The listed dimensions also differ between 10.4 x 5.2 x 2.4 centimetres and 10.4L x 5.2W x 2.6Th centimetres. The listing gives a 30W iPhone 14 charge-to-50% claim in 30 minutes, but another detail names iPhone 15 as a compatible model. It also lists a funnel as an included component, while the feature copy names a welcome guide and does not mention a funnel. Confirm the selected listing's output, dimensions, compatibility and package contents before purchase.

Customer feedback highlights pocket-friendly size, portability and the convenience of the built-in USB-C cable, with positive comments about performance and value. Charging speed is mixed, and reliability feedback includes reports of units stopping after around two weeks. The listed 30W claim and compact dimensions may suit portable phone charging, but the output discrepancy makes charging expectations worth checking, and the reported reliability concerns matter for buyers depending on a power bank regularly.

Frequently asked questions
Does the Anker Nano A1259 have a built-in cable?
Yes. The title and feature description identify an integrated USB-C cable, described as usable for charging devices and recharging the power bank.
What charging output does the listing claim?
The title and feature copy claim 30W, but the detailed A+ specification states 24W maximum total wattage. Confirm the output details for the listing you select.
How large is the power bank?
Two dimensions are listed: 10.4 x 5.2 x 2.4 centimetres and 10.4L x 5.2W x 2.6Th centimetres. The listing does not resolve this discrepancy.
What comes in the package?
The included-components field names a funnel. Feature copy instead describes the power bank and a welcome guide, so the package contents are unclear and should be checked against the selected listing.
