WurkkosH1 Fast Charging Portable Charger， 5000mAh Power Bank with Clip, Flashlight Portable Charger External Battery with USB-C 5V/3A Output and Input is Compatible with 18650 and 21700 Batteries

I previously bought two Wurkkos flashlights, and this is my third purchase. This charger meets my needs with its compact size and fast charging speed. The removable battery is the best feature, allowing me to replace it without discarding the charger.

This is a solid and compact portable charger. The easily replaceable 21700 battery is the part I like the most. The included battery appears close to the claimed 5000mah according to my charger. It's a good battery. With that said, I feel the programming that cut off the power to this charger to protect the battery from over-discharging is too conservative. Charging through the USB C port puts back in just under 4000mah before it stops charging. I feel having 1000mah unused is a little too much. Overall, it's a good charger although the msrp is a little high.

The media could not be loaded. The Wurkkos H1 power bank is compact, convenient, and surprisingly versatile for its size. It charges phones quickly and delivers reliable performance when you need it most. Whether you’re out hiking or just need backup power in your bag, this little unit fits easily and doesn’t weigh you down.What really sets it apart is its flexibility—you can carry it multiple ways, and it accepts different battery types like 21700 or 18650 cells. If I could change one thing, I’d add a small button to check the battery level without needing to plug something in. As it stands, the only way to see the battery level is by either charging a device or charging the power bank itself. If anything changes with this power bank, I’ll update this review.

I purchased two of these. One works well, but one has parasitic drain that will not only drain the battery quickly, but will drain it well past the point where Low Voltage Protection should allow, and to a point where charging the battery afterwards is a potential danger.It may be a rare case of bad luck, as QA is never 100.00000% good, but I would advise "mechanical lockout" by twisting the tailcap to disconnect the battery until you actually use this to avoid the potential issue I had with one of the two units I bought.Not a problem for those who have specialized knowledge, but a potential issue for the vast majority of people who do not have a background in electrical engineering, or even a "You're a geek!" level of interest in enthusiast-grade flashlights.

Solid metal case, feels quality like most of their lights. Battery has good capacity and charges devices quick. The pocket clip is strong too which is great on a powerbank

I bought 7 different Wurkkos flashlights, several of them get so hot you can barely hold them, while the others stay cool. Contacted Wurkkos support multiple times and they won't help me. In the end they will only offer 5% off another purchase. No help for their products.

Absolutely love this. It supports fast charging with a "fast charging" cable.
