The Anker Zolo 10K takes first place in this guide. It is a 10,000mAh power bank with a 13.7cm USB-C cable built into the body, a 30W output claim, a £18.99 price and 11,066 ratings averaging 4.6 out of 5. Anker says it will take an iPhone 15 from 0 to 57% in 30 minutes, give an iPhone 15 up to two full charges, and give a Samsung S24 1.94 charges.

What puts it at the top of this particular guide is not the headline capacity — all eight listings here lead with 10,000mAh — but the number of small disagreements inside its own listing. The spec table says "Portable: No" and "Is Product Cordless: No" on a product described in the same listing as "mighty compact" and "ideal for travel". It gives "Power Source: Corded Electric" alongside "Is Electric: No", 3 in one port field against 2 in another, and 1.66 Amps next to an output current of 3 Amps. Everything below comes from the Amazon listing as it is written, not from any testing we have carried out.

## Questions people ask

**Is the Anker Zolo 10K actually cordless?**

Anker's bullets describe a compact power bank for travel, but the listing's own spec table says "Is Product Cordless: No" and "Portable: No", and gives "Power Source: Corded Electric". Those fields sit in the same table as "Reusability: Rechargeable".

**How many devices can it charge at once?**

The listing does not say clearly. It gives 3 in the Number of Ports field and 2 in the Number of Outlets field, and does not explain the difference between the two figures.

**How long does the power bank itself take to recharge?**

The listing has a field reading "Battery Charge Time: 30 minutes", but the same 30 minutes is what Anker's bullet claims for taking an iPhone 15 from 0 to 57%. The input figure quoted for the bank is 20W, and no full recharge time for the 10,000mAh battery is given.

**Does 10,000mAh really mean two full phone charges?**

Anker claims up to 2 full charges for an iPhone 15 and 1.94 charges for a Samsung S24, and notes in the same bullet that the 10,000mAh total is made up of two 5,000mAh cells.

**What is in the box?**

"What You Get" lists the Anker Zolo Power Bank (10K, 30W, Built-In USB-C Cable 13.7cm/5.4 in), a welcome guide and an 18-month warranty. No separate charging cable is listed, although one buyer review on the listing says an extra USB-C to USB-C cable came with their order.

**Which phones does it work with?**

The compatible list covers iPhone 12 through iPhone 16, the iPhone SE (1st, 2nd and 3rd gen), Google Pixel 7, 7 Pro, 7a, 8 and 8 Pro, and the Samsung Galaxy S23 and S24 ranges. A separate field, "Compatible Phone Models", lists only the Audiovox CDM3000.
