Rank #8 in Best 10000mAh Power Bank 2026: 8 Ranked, and the Numbers That Do Not Add Up
Zmmyuluo N1 10,000mAh Power Bank with 4 Built-In Cables
Price and rating as shown on Amazon when we collected them. Both change.
The Zmmyuluo N1 sits at number eight in this guide and is one of the cheapest entries in it at £15.99. It is a 10,000mAh battery pack with four cables built into the shell — USB-C, Lightning, Micro USB and a USB-A input cable — so the pitch is that you can leave your own cables at home. The listing carries a 4.6 out of 5 rating from 794 ratings.
The spec table underneath is where it gets interesting. This is one of the few listings in the guide that answers "Portable: Yes", which sounds like a point in its favour — until the same table says "Is Product Cordless: No" and lists the power source as Corded Electric, on a product whose entire purpose is being carried in a bag. The bullet points also count four built-in cables while the spec table counts three ports. Everything on this page comes from the Amazon listing rather than from any testing we have carried out.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Love this. So handy that the leads are built in. Seems to charge quickly and I can get a couple of charges for my phone from it. Took on holiday, quite lightweight, decent size, and did what we needed it to when we were out all day.”
Verified purchase“Seems good. Only received this morning. A little thicker than I was expecting. I like the built in cables.”
