Unusual rechargeable dehumidifier
Added 2024-01-15 06:51:46 +0000 UTCBy far the most unusual part of this rather neat product is the heater. It is a very odd twist on standard technology, that allows greater heat transfer to the air.
The silica-gel cartridges seem to dry quite quickly for reuse due to the combination of heat and a low flow of air to drive the moisture out.
Comments
My experiment of an adaptor and sawn-off drink bottle flopped (literally) with the heat.

2024-01-17 18:01:07 +0000 UTCI have that exact unit. I used it to keep the humidity in my gun safe down. Mine did not come with the boot drying attachment. It worked well, just needed to remember to pull it out and let it sit on the heater about once a week.
