If youve found yourself Googling the Kampa Diddy only to discover its no longer available, we felt it was our duty to track down the best alternatives and do the hard work for you. Read on for our pick of the best compact electric fan heaters for camping in 2025.If youre new to camping with an electric hook-up (EHU) and wondering what all the fuss is about, a small, low-wattage electric fan heater is genuinely one of the best bits of kit you can invest in for three-season camping. Theres nothing quite like waking up on a crisp spring morning, flicking on a heater and waiting all of about 30 seconds before the chill is banished from your tent. The key things to look for in a camping fan heater are compact size (we know that your boot space is precious!), low wattage settings to avoid tripping the campsite EHU, safety features including tip-over cut-off and overheat protection, and cool-touch housing, especially important if youre camping with kids or pets. All four of the options below tick every one of those boxes.A quick note on EHU limitsMost UK campsites run either a 6 amp or 10 amp supply. At 6 amps thats roughly 1,380W of power for everything on your pitch heater, phone chargers, lights and all. At 10 amps youve got around 2,300W to play with. Always factor in your other devices and stick to lower wattage settings to avoid tripping out the supply.1. Kampa Cuboid PTC Fan HeaterIf you loved the Diddy and want something that feels like a direct spiritual successor, the Kampa Cuboid is your answer. Its from the same brand, designed with the same camper in mind, and slots into the same space in your boot without complaint its just a little more refined.The key upgrade over the original Diddy is the PTC (Positive Temperature Coefficient) ceramic heating element. PTC technology heats faster and more efficiently than a standard resistance wire, and crucially, its safer if the airflow is ever obstructed, the element naturally self-regulates rather than getting dangerously hot. It also has three settings, a cooling fan mode, 750W and 1500W so it genuinely earns its boot space all year round, not just when the temperature dips.Like the Diddy, it features cool-touch housing, thermal overheat protection, and an automatic tip-over cut-off switch. It has a variable thermostat too, which the Diddy notably lacked, making it much easier to maintain a comfortable temperature without constantly fiddling with the dial.Key specsHeat settings: Cooling fan / 750W / 1500WTechnology: PTC ceramicSafety: Tip-over cut-off, overheat protection, cool-touch housingVariable thermostat: Yes Buy the Kampa Cuboid Fan Heater on Amazon2. Status 1500W Oscillating Ceramic HeaterIf youre looking for a no-fuss, great value option that ticks all the key boxes without breaking the bank, the Status 1500W PTC Heater with Oscillation, available exclusively at Go Outdoors, is a really solid pick. Status is a budget-friendly electronics brand that consistently delivers reliable performance at accessible prices, and this heater is a fine example of that.Like the other options on this list, it uses PTC ceramic technology for fast, efficient heat, and the oscillation function means warm air is swept around your tent or awning rather than concentrated in one spot a genuinely useful feature in a camping context where you want the whole space to warm up quickly. At 1500W itll handle a tent or awning with ease on a standard EHU pitch, and the safety credentials, tip-over protection and overheat cut-off, are exactly what you need when using a heater in an enclosed canvas space.Its a particularly good shout if you want to keep costs down or are buying a camping heater for the first time and dont want to commit to a pricier model. Sometimes simple and reliable is exactly what you need, and this one delivers.Key specsHeat output: 1500WTechnology: PTC ceramic with oscillationSafety: Tip-over protection, overheat protectionWhere to buy: Go Outdoors Buy the Status Oscilating Ceramic Heater at Go Outdoors3. Pro Breeze Mini Ceramic Fan HeaterIf you want something with a bit more grunt, particularly for larger awnings or family tents, the Pro Breeze Mini Ceramic Fan Heater is worth a serious look. Its still compact enough to pack easily, but its 2000W high setting means it can handle a bigger space much more effectively than smaller 1500W models.It features a built-in adjustable thermostat and two heat settings (1200W and 2000W) alongside a cool fan mode, so youve got flexibility depending on your pitchs power limits. The safety credentials are solid too overheat protection and a tip-over switch come as standard, and the ceramic element means it heats up almost instantly.Worth noting: the 2000W setting will push close to the limits on a 10 amp EHU, particularly if you have other things plugged in, so youll want to be mindful of your total power usage. On the 1200W setting though, its perfectly manageable on most modern campsites and still impressively effective.Key specsHeat settings: Cool fan / 1200W / 2000WTechnology: CeramicSafety: Tip-over cut-off, overheat protectionThermostat: Adjustable Buy the Pro Breeze Mini Ceramic Fan Heater on Amazon4. Dreo Electric Space HeaterIf you want the most feature-packed option on this list, the Dreo Electric Space Heater punches well above its price point and brings a suite of genuinely useful features that make it an outstanding choice for camping and home use alike.Like the Outdoor Revolution above, it oscillates sweeping 70 to distribute warm air evenly across your tent or awning rather than blasting one spot. But the Dreo goes further with a remote control (very handy when youre cosy in your sleeping bag and dont fancy getting up), a 112 hour programmable timer, and an ECO mode that automatically adjusts output to maintain your chosen temperature efficiently without wasting energy.It runs at up to 1500W via PTC ceramic technology across three modes and three fan speeds, so youve got plenty of flexibility to dial in exactly the right level of warmth for your pitch. Safety features are comprehensive overheat and tip-over protection as standard and the compact, upright design means it tucks neatly into a corner of your tent without taking up valuable floor space. If youre going to upgrade from the Diddy, this is the one to go for.Key specsHeat settings: 3 modes / 3 speeds / up to 1500WTechnology: PTC ceramic with 70 oscillationSafety: Tip-over protection, overheat protectionExtras: Remote control, 112H timer, ECO mode, thermostatAvailable from: Amazon Buy the Dreo Electric Space Heater on AmazonFinal tips for using an electric heater in your tentAlways use a proper, outdoor-rated EHU cable with a built-in RCD (Residual Current Device) never use an indoor extension lead.Keep your heater on a flat, stable surface well away from tent fabric, sleeping bags and any other flammable materials. The general rule is a minimum of one metre clearance on all sides.Never leave a fan heater running unattended for long periods and always switch it off before you go to sleep a log burner in a glamping dome is one thing, but a fan heater in a tent is a different matter. A small investment in a quality sleeping bag and a good base layer will serve you better overnight than leaving a heater running.Check your campsites EHU amperage before you arrive and plan your power usage accordingly most modern sites are 10-16 amps, but some older sites still run 6 amp supplies.Have you tried any of these heaters?
