It depends on which model you have.
At full volume, the Original DemerBox should last 50 hours. The new DB2 model at full volume will last for about 40 hours of playback.
Remember, if you’re charging a device at the same time, that playback time will decrease. But you should still get a great many hours at max volume.
94db @ 1ft. DemerBox is loud enough for many situations, but not all.
For instance, it’s loud enough for a backyard birthday party with a dozen people, but not loud enough for a crowd of 100. Most people who buy are satisfied with the volume it puts out. Try one out, and if you find it’s not loud enough, send it back within 30 days for a full refund.
Basically anything that fits!
Keys, wallet, socks, a sandwich. Playing music with stuff in your DemerBox will change the tone and might reduce the bass response. When I travel (this is Demer writing this) I pack my DemerBox into my bag and stuff it full of socks and t-shirts to save space.
When you’re using the DemerBox in a pool or at the lake, put a couple beverages inside to keep the speakers facing upright.
The only thing you don’t want to put in your DemerBox is water. Cold drinks are fine, but anything that could drip into the internal ports could cause an issue.
We include a Quick Start Guide with every DemerBox purchase and we email a Tips & Tricks Guide. Sometimes customers lose the guide or delete the email accidentally.
