MAXSafes Dehumidifier Rod/High Power (18in)

These get considerably hotter than the 7w version, just plug & play. Make sure you put them where you want them before plugging them in. They do heat up quick! Same size, perfect fit, only had for about a month & working great! I am using two of them to keep my battery compartment warm on my trailer during the cold months. Don't use a ton of power but put off good heat! Add a small 2.2w usb fan & the compartment has stayed nice & warm! No worry about it getting below freezing so far. Only had them a month if that, no problems!

Gets hot like it supposed to. Just not sure if it actually reduces humidity to any noticeable degree. For the cheap price of purchase and running it I'll keep it in my safe and hope it helps.

I placed one of these in my gun safe about six months ago. My med/large gun safe is located in my basement and I have always had to keep close watch to make sure my guns didn’t pickup rust. Now, the safe is pretty stable at 30% relative humidity. It took a while to drop that low as it is an old safe and has been in my pole barn and basement for over 15 years. With its detachable plug it was very easy to install, just drill a hole for the cord and attach the plug and it’s good to go.

Was great

Works great, easy to install, keeps a good temperature to prevent rusting items in the safe.
