The LED lighthead is removable to offer the USB connection for charging a smartphone or other USB chargeable device.
It is a nice feature to have a spare battery for charging your smartphone for long days when away from an outlet. I have used the light and battery on trips and both functions are very helpful.
Here is a look at the Side Mount handlebar attachment above the handlebar. The Side Mount is made of plastic and when riding over rough roads there is noticeable vibration of the light. It would be good to have handlebar mount that is a bit more sturdy.
Rotating and holding the lighthead for a second turns the light on/off and a quick rotation cycles through the different light modes.
At 1,000 lumens the PWR Trail is very bright in the Max light mode which makes it a good light for seeing a lot of details for on and off road riding.
The lower output levels also work well and provide much longer run times if needed. Here is a breakdown of the run times:
Max 1,000 Lumens: 2 hours
Mid 550 Lumens: 3 hours
Stamina 80 Lumens: 21 hours
Pulse 300 Lumens: 8 hours
Strobe Flash 225 Lumens: 14 hours
Eco-Flash 15 Lumens: 300 hours
The strobing modes work very well for being seen day or night.
The Side Mount and light can also be located under the handlebar.
The red button releases the lighthead from the battery. To the right of that is the track for attachment to the Side Mount handlebar attachment.
There are 2 indentations along the track where the Side Mount metal pin locks the light into place. That correlates into 2 locations where the light can be attached to the Side Mount.
This is the Side Mount that the light slides onto. In this view you can see the metal pin extended out that locks the light into position.
The Side Mount has a quick release lever for quick removal from the handlebar.
There is a USB to micro USB cord that comes with the light for charging and I used an Apple charge plug to connect to the wall outlet.
Full charge time is 5 hours but it can be faster if you use an iPad charger, according to Knog.
The brightness of some of the light modes can be adjusted as well as the frequency of some of the strobing modes. The number and types of modes can also be customized to your preferences.
Overall the Knog PWR is an impressive light & extra battery with a bunch of features and expandability.
The variety of light brightness options make it a great light for on/off road riding and the flashing light mode will get the attention of others on the road.
The battery function is great for charging a smartphone on longer trips away from an outlet. And it is impressive that Knog is working on additional accessory options like the headlamp, lantern, and speaker.
The handlebar mount could be more robust to minimize vibration on rough terrain.
