Carbon dioxide detectors
Carbon dioxide detectors (or CO2 detectors) measure carbon dioxide, which is very unlikely to reach dangerous levels in any vehicle. High CO2 levels could cause drowsiness, which is a risk especially when driving. Don't confuse carbon dioxide detectors with carbon monoxide (CO) detectors; be sure you're buying kind you want. Products listed here are battery powered; plug-in (AC) models are usually cheaper but not as well suited for nomadic living.

Carbon monoxide detectors
Carbon monoxide detectors (or CO detectors) are important for safety, especially when sleeping in your vehicle or using any appliance that burns fuel. Look for certifications to ensure that it actually detects CO well, such as "USA NIST". Note that CO2 detectors (not CO) measure carbon dioxide, which is very unlikely to reach dangerous levels in any vehicle. Be sure you're buying kind of detector you want. Products listed here are battery powered; plug-in (AC) models are usually cheaper but not as well suited for nomadic living. Many products detect multiple gases including CO, so if you want additional protection, consider a gas monitor instead of a CO detector.

Portable fridges
The 12v portable refrigerator is a must-have for anyone who lives in a vehicle! Most models use surprisingly little power, even when set to freezing temps! Some come with their own batteries, and others must be plugged in to an external power source.

Portable power stations
Portable power stations are a convenient way to get electricity for your devices and small appliances while camping or on the road. They don't make their own power; they are large batteries that can be charged from an outlet, your car, or solar panels. These are sometimes marketed as "solar generators" (recharged via solar) and can be used in place of fuel-powered generators for some uses. Popular brands include Bluetti, Jackery, EcoFlow, GoalZero, and Anker. Smaller brands often use cheaper batteries and components, and are less likely to provide detailed product specifications, so don't shop on price alone. To appear on this list, a device must have at least 100Wh capacity.
