Great pass through power bank for my knog lights as well as outbound light. perfect size, and fits on bike with ease. Mount is straight forward and not complicated which is what every cyclist needs and wants. On a plus the PWR bank also charged my phone and bike computer
I am steadily building my PWR Bank system. The medium power bank is, to me, the core of the system. Whether for hiking, camping or cycling the capacity versus weight make it the most versatile for my outdoor activities. The variety of light head and battery combinations is amazing and so adaptable you can easily find the setup to fit your needs.
Great battery - charges up quick, handy that it can be strapped most anywhere.
The cap is a bit tough at times to pop off, especially with cold hands in the dark.
I had a Topeak USB battery pack designed for road biking. I probably bought it about 2012. When it died, I tried to replace it with the same, only to find them no longer available - anywhere. That was a blessing in disguise, as I found Knog. Better batteries, better form factor, more mounts, more flexibility, and state-of-the-art design. The PWR Bank is easy to charge, easy to see the remaining capacity, and it lasts at least 3 and sometimes 4 rides powering an iPhone 12 Pro Max. I'll be buying many more Knog products in the future.
Very well designed and plenty of power. Have been using for daily commuting over the last 2 weeks with no issues and still on 4 bars. Very happy!
