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.
Pros and cons
- Four cables built in, no loose cables to carry
- 22.5W fast charge, rated 50 percent in 30 minutes
- Six outputs let several devices charge at once
- Smaller and lighter than the maker's earlier 15,000mAh design
- 15,000mAh capacity still adds meaningful pocket weight
- Built in cables cannot be swapped if one wears out
Performance notes
The 22.5W fast charging spec is rated to bring a phone to 50 percent in about 30 minutes. Capacity is listed at roughly 3.5 iPhone 17 charges, 2.5 Samsung S26 Plus charges, or 20 AirPods Pro charges. Six outputs, including the four built in cables plus the bi directional Type C port, allow multiple devices to draw power from the bank at once.
