Overview
A 15,000mAh power bank with four cables built into the body, USB A, Type C, iOS and Micro, rated to charge an iPhone about 3.5 times or a Samsung S26 Plus about 2.5 times before it needs a recharge itself.
The pitch here is not carrying loose cables: all four connector types fold out of the bank itself, and it charges through six outputs at once via a bi directional Type C port. HELLEE also claims a smaller, lighter body than typical 15,000mAh banks in this class.
- 15,000mAh with 4 built in cables
- 22.5W fast charge, 50 percent in 30 minutes
- 6 output ports including bi directional Type C
- Rated for about 3.5 iPhone or 2.5 Samsung charges
Who it's for
Travelers or commuters who want one power bank that covers iPhone, Android and older Micro USB devices without packing separate cables. Useful for charging multiple devices from one bank at the same time.
