HELLEE 22.5W 10,000mAh Power Bank with 4 Built-In Cables

The HELLEE Power Bank Fast Charging 10000mAh is the seventh entry in this guide. It costs £16.98, carries a 4.5-star average from 5,803 ratings, and its listing leads with 22.5W charging over PD3.0 and QC4.0, a 10,000mAh cell and four cables built into the shell so you do not have to pack your own. The item weight field gives 180g, and the portability field reads "Yes".

Where this listing gets slippery is in its own counting. The title and the first bullet promise four integrated cords — iPhone/iPad, Micro USB, USB-C and USB-A. A later bullet describes three built-in cables plus two USB-A ports and one USB-C port, and says the bank can run six devices at once; the specification table, in the same listing, gives the number of ports as 3. The dimensions disagree too: the bullet calls it 1.9cm thick and 11.5cm long, while the item dimensions field says 10.9 x 6.9 x 1.7cm. On weight it is the more convincing of the two slimming claims in this guide — 180g here against the 250g the Anker PowerCore Slim's own spec table lists. Everything on this page comes from the Amazon listing, not from any testing we carried out.
