MD100 Rechargeable Mini Desiccant Twin Pack
The MD100 is a compact rechargeable mini desiccant dehumidifier designed to use in small spaces like cupboards, wardrobes, storage boxes and more, or as a car dehumidifier.
Once charged, place this compact dehumidifier where desired and leave it to work away. Once the indicator window turns pink, the unit needs to be recharged. Recharging the unit regenerates the crystals so that they can dehumidify effectively again. Once the indicator window turns blue, the unit is charged, restored and ready to use again.
This compact dehumidifier is ideal for protecting precious items like your camera, clothes, and more from damp. It can be charged 1000s of times and has a very long life span of around 10 years.
Features:
- Stops mould developing in drawers, cupboards and wardrobes and cars - keeping areas fresher and drier
- Favourite with collectors as it keeps valuables dry - saving 1000s of pounds
- Protects expensive equipment or tools stored in boxes or confined spaces
- Does not need electrical power to operate, making it truly portable
- Recharges quickly from a plug-in cable, lifetime durability
- Changes colour when crystals have absorbed the maximum amount of water
- Extracts water naturally, drying the surrounding air without releasing any chemicals or odours
- Economical to recharge, MD100 uses only 25W per hour when recharging (~10 hrs), which is less than running a compressor dehumidifier for one hour.
- You may not need to recharge this unit for up to two weeks, depending on the localised humidity.
- MD100 does not over-dry as it only absorbs the excess humidity
- The package contains 2 x MD100 mini dehumidifiers and one charging cable
Please note:
There is a heating element inside of the MD100 which slowly releases the humidity during regeneration.
Ideally, you should recharge the MD100 in a dry room or a room where a standard dehumidifier is used.
This product does not contain any cobalt chloride. Colour changes occur through a silicon dioxide process; making this a very safe and non-toxic appliance.
Question from James Wilson: Asked on 06/01/2026 How long do these take charge back up to blue
Hi, To recharge the ElectriQ MD100 mini dehumidifier, simply plug it into a wall socket. It normally takes around 10–15 hours of charging for the crystals to turn blue, which means the unit is fully recharged and ready to use again. Do not leave it charging for more than 18 hours.
Thank you.
Question from Ellie: Asked on 18/11/2025 Does this help with condensation?
Hi, The electriQ Rechargeable Mini Dehumidifier (MD100) helps reduce condensation by removing excess moisture from the air in smaller spaces. It's ideal for areas like bathrooms or bedrooms, but for larger spaces or high humidity, a more powerful dehumidifier may be needed.
Thank you.
Question from Paul: Asked on 09/11/2025 What is the lowest temperature it works at?
Hi Paul,The electriQ Rechargeable Portable Mini Dehumidifier MD100 is designed to operate most effectively in temperatures between 5°C and 50°C (41°F to 122°F). It may not function properly in colder environments, as the moisture in the air could freeze, hindering its performance.Thanks!
Question from Gez: Asked on 06/11/2025 Does it power off automatically when full ?
Hi, The electriQ MD100 Rechargeable Portable Mini Dehumidifier does not automatically power off when it is “full.” This model uses moisture-absorbing crystals (desiccant) rather than collecting water in a tank. When the crystals become saturated, they change colour to pink, indicating that the unit has absorbed as much moisture as it can. At this point, the unit must be manually recharged by plugging it into a wall socket for 10–15 hours. It does not have a water-tank sensor or automatic shut-off feature.
Thank you.
Question from N Jackson: Asked on 28/10/2025 Will this work outside in a car?
Hi, The MD100 dehumidifier is designed to be used in small, confined spaces where a standard dehumidifier cannot be used—such as drawers, cupboards, storage boxes, and cars. It absorbs moisture with rechargeable crystals, helping to reduce condensation and keep your car interior drier.
Thank you.
Question from Liz: Asked on 24/10/2025 Could you use thus in a shed to help in the winter.
Hi Liz,The electriQ Rechargeable Portable Mini Dehumidifier (MD100) can be quite effective in a shed during the winter by helping to reduce humidity, preventing condensation, mold, and rust on tools or equipment. Its portable and rechargeable design makes it convenient for spaces without electrical outlets, and it's ideal for smaller sheds. However, for larger sheds or areas with high humidity, you may need multiple units or a more powerful dehumidifier.Thanks!
Question from Davebehave: Asked on 15/01/2025 You say that once it’s full of water you recharge it and can you explain how it does that as I’m sure it would cause water vapour in the air ie steam so how does it dry it out without adding moisture in the air
Hi Dave,
Thanks for getting in touch
That's correct - Ideally, you should recharge the MD100 in a dry room or a room where a standard dehumidifier is used.
Hope this helps,
Sam
