Best Battery-Powered Tent Heater Alternative: DEWALT DXH12B Portable Heater (Actually Uses DeWALT 20V MAX or FlexVolt Batteries + 3 USB Ports) Ok, there are no cordless heaters that would run on batteries, you might be thinking. What’s the next best thing? The main power is still generated by propane. This is one of the most capable battery-powered heater alternatives; it can produce up to 12,000 BTU of heat when running on 100% capacity. At the lowest setting, the 1 lb propane tank is can provide heat for up to 7 hours. Of course, you can always bring a 20 lbs propane tank with you on camping and refuel the DEWALT DXH12B 20 times. Generac is one of the leading generator producers. This Generac 7117 Gp2200I model is the most fitting unit for the battery-powered heater alternative with a generator + electric heater combo. Here’s the deal: It has a lower heating output than a standard heater (below 5,100 BTU). However, it still has a 1 lb propane tank. That means that it can generate 3,800 BTU for quite some time (5.6 hours, to be exact).

Any battery-powered heater would operate by battery generating electricity to run an electric heater. A standard electric space heater is a 1,500W heater. Batteries have, as we have we surmised so far, too low a capacity to run battery-operated heaters anyway. Power source accepts Makita 18V LXT® and Compact Lithium-Ion Batteries; features a 2.1A USB power port for charging portable electronic devices To power a 1,500W electric heater as a battery would theoretically do, you need a generator with at least 1,500W running watts. Generac 7117 Gp2200I can generate 1,700W running watts (and 2,300W starting watts). That makes it one of the smallest (and most cost-efficient) possible generators to power a standard electric space heater. Now imagine that you would have to use a battery to operate a heater for 10 hours. What size battery would you need? You would need a 1,250Ah 12V battery that weighs 300-500 lbs.Propane is actually a very rich power source. A single gallon of propane contains 91,500 BTU of heating power. The burning efficiency of propane is very close to 100% making these units very energy efficent. That’s very important when you want a portable heater. Note: You can find a whole lot of articles about the best battery-operated heater on the internet. None of those heaters are actually powered by a battery. They are 500W to 1,500W space heaters that require a standard 120V outlet and a 60 Hz circuit. You will immediately find out that those ‘battery-powered heaters’ don’t even have a battery, for example. With a range of seven temperature settings to keep contents either cool or warm, this cooler also has a USB output port, and an LED display which shows the inside temperature and battery fuel gauge. Due to high heating output and indoor safety features, the DEWALT DXH12B is the closest thing to the best battery-operated tent heater. It has a factory-installed Oxygen Depletion Sensor (ODS) and a thermoelectric safety valve. Both of these make the use of DEWALT DXH12B inside the tent much safer. With below 10 lbs total weight (9 lbs, to be exact), it is very portable. In fact, if there were a battery-operated heater for camping, it should have pretty much the same specifications as the Mr. Heater MH18B.

In practice, however, even the big 100 Ah 12V battery would keep a standard 1,500W space heater running for less than 1 hour ( 48 minutes, to be exact; we did some calculations on how long can a battery power a heater at the end of this article). For heating a house, you need 10,000s BTUs. No battery is large enough to provide that. Example: How long will a big 100 Ah 12V battery be able to provide 60,000 BTU of heat needed to heat a 1,500 sq ft house?Well, if we want to power a 1,500W heater for 1 hour with a battery, we will need a 125 Ah 12V battery. According to EPEC Engineering Technologies, such a 125 Ah 12V lead-acid battery weighs between 30 and 50 lbs. Outtake: It’s a 30-50 lbs battery that powers a heater for only 1 hour. The most optimum (yes costly) way to create an off-grid battery-operated heater alternative is to use an electricity generator or a battery-operated power station to power an electric heater. Of course, in this case, you would need 2 units: either a generator or power station and an electric heater. We will look at the best generator and the best power station to recreate a battery-powered heater.

Best Portable Power Station + Electric Heater: EF ECOFLOW DELTA Power Station (Can Be Recharged With A 12V Car Charger)

EF ECOFLOW DELTA includes a 1260Wh rechargeable battery. Now, if you have a standard 1,500W heater, it will use 1,500Wh (watt-hours) every hour. That means that you can, even if the power station is charged to 100%, run such a heater at its maximum heating output for 0.7 hours or about 42 minutes. After that, you will need to recharge the battery.

You usually put it in your garage because, unlike the non-existing big battery-powered heaters, these units can generate quite a lot of noise. The added advantage of the Mr. Heater MH60QFAV is the silencing QBT technology that can reduce the noise generation of these big battery-powered heating alternatives by 50%. Now for the batteries part: Propane is used to produce the heating output. On top of that, DEWALT DXH12B has 3 USB chargers (to charge your phones, for example), a LED light on top (useful when the night falls), and a fan that distributes the heat evenly. All of these are electric-powered featured and to power them, DEWALT DXH12B uses 20V MAX or FlexVolt batteries. The best alternative to the home heating battery-powered heater are the big propane heaters. They are in a shape of a torpedo so we generally refer to them as ‘torpedo’ heaters. Or even What are the Top 10 affordable (best budget, best cheap, or even best expensive!!!) Makita Battery Heater available? Etc. Of course, the beauty of generators is that can always refuel them. Refueling takes much less time than battery charging; that would be the case if a battery-powered heater existed, of course.For power outages, you would require a battery-operated heater for a room or even the whole house. For high heating requirements, the best alternative to battery-operated heaters are the big propane torpedo heaters. These can generate anywhere from 30,000 BTU to 100,000+ BTU and and can heat up an entire house in an event of an outage. Mr. Heater MH18B is the most popular battery-powered heater for camping alternatives. Its 1 lb propane tank can generate 4,000 BTU (low setting) to 9,000 BTU (high setting) of heating output. Here’s the thing: You need a generator or a power station that will produce at least 1,500W running watts and more than 2,000W running watts. Only such units can be used to recreate battery-powered heaters. Now, if you want to use battery-powered heating for power outages (we all know what happened in Texas in February 2021), no battery will cut it.
