Cheap, and a 10-pack means a spare on hand if one plug is lost or damaged
Generic fit — measure your unit's drain outlet diameter before ordering, per this category's own buying guidance
Best for: Anyone whose portable AC has lost or damaged its original drain plug and has confirmed a 20mm outlet before ordering.
Spare parts for portable air conditioners — drain plugs, castor wheels, window bracket clips — sell in much smaller volumes than filters or hoses, and turnover between chassis generations is fast. This 20mm drain plug set is a real, confirmed listing, but it’s a generic-fit part rather than one built for a specific reviewed model: measure your own unit’s outlet before ordering.
Why a spare drain plug matters
A missing or perished drain plug on a portable AC’s condensate outlet means water leaking from the unit during dehumidify or cooling cycles, rather than draining or evaporating as designed. It’s a small, cheap part, but one that’s easy to lose during off-season storage or a move.

Dreo's own demineralization cartridge, sold as a 3-pack, stated to fit its HM311, HM306 and HM524S humidifiers. Dreo's own listing does not name the DR-HHM006 reviewed on this site as compatible, so we're not claiming a fit — this entry reports the part honestly as an official Dreo accessory for a different segment of the brand's range. Confirmed with a live offer and 2 sellers on Amazon.de.

EBERG's ClimaCover storage cover, sized L, is built to fit portable air conditioners, dehumidifiers and air purifiers alike — a broader stated fit than the tower-fan cover in this family. It has a vented panel and a drawstring closure rather than being fully sealed. Confirmed with a live offer on Amazon.de; we did not find a listing on the other three markets we checked.
Stated fit
Portable air conditioners, dehumidifiers, air purifiers (size L)
Closure
Drawstring, with a vented panel
EAN
5903357331641
One cover sized for three different appliance categories in this network, rather than one model only
The vented panel is a genuine design choice against trapping residual moisture — relevant for dehumidifiers especially
Only one seller confirmed at the time of checking — no second offer to compare
Best for: Anyone storing a portable air conditioner, dehumidifier, or air purifier off-season and wanting a cover with ventilation rather than a fully sealed bag.
Elektrobock's TS05 is a digital plug-in thermostat with a relay output stated as max. 16 A, switching a connected heater between +3 °C and +40 °C in 0.5 °C steps, with a frost-protection floor at 3 °C and settings that Elektrobock states survive a power cut.
Max. load
230 V / 50 Hz, relay output stated as max. 16 A — Elektrobock does not publish a watt figure directly; at 230 V that computes to about 3 680 W
Temperature range
+3 °C to +40 °C, adjustable in 0.5 °C steps
Hysteresis
0.5 °C, with a stated measurement accuracy of ±0.5 °C
Frost protection
Built-in, engaging at +3 °C
Power-cut behaviour
Retains its settings through a power outage and resumes automatically, per Elektrobock

Amazon reference
B00YURX7BI (EAN 8594012221703, plus three further regional EANs on the German listing) — sold and shipped by Amazon on DE at the time we checked. A catalog page exists on FR/IT/ES/GB under a different ASIN (B01BVKTFXU) but carried no live offer or price on any of the four at check time; no listing found at all on Amazon US
Widest and coldest-reaching range of the three outlet thermostats in this hub: +3 °C to +40 °C, against +5 °C to +30 °C on the ChiliTec ST35 and the McPower TCU-330
A stated frost-protection floor at +3 °C, which neither of the analog units in this hub publishes
States its output as "max. 16 A" rather than a watt figure — the 3 680 W equivalent is our own arithmetic at 230 V, not a number Elektrobock itself publishes
Best for: A cold garage, shed, or outbuilding where frost protection and a wide temperature range matter as much as the day-to-day thermostat function, and where settings surviving a power cut is worth having.
