I have a gas barbecue grill , I have been using my Skilhunt H15 as well as the Coleman Peak One lantern, for light.
So I am considering an alternative.
I want to use rechargeable cells as the power source, as I don’t have an outlet nearby.
The choices are the clamp-on the handle style, or the table top desk type.
I don’t want to spend much I’d like to be under $20
Here are samples
I’m wondering if anyone has any experience with either of these styles.
So I bought this from GearBest.
Bike Handlebar Mount
Today it arrived, I couldn’t be happier. I have the Skilhunt H15 AA/14500 in Neutral White, This device fits both my grill handle and the headlamp.
This is a two clamp design, the single clamp works well for my headlamp, and I’ll the other pieces on my bicycle.
