WIRED

New LiFePO4 battery is rated for 4,000 charge cycles. Higher-output USB charging (140 watts). High amp output for tying into van and overlanding setups. 4 AC outlets. Excellent vibration resistance for off-road use.

TIRED

No internal heater for low-temp charging. Price per watt-hour is on the high side.

The heart of a reliable, powerful off-grid mobile electrical system is in the battery. Whether you're overlanding full-time with a remote job or just working from the road for a few days, you need a trustworthy power system that can handle personal devices, portable fridge, water pump, Starlink, and more.

I've built my own mobile systems, even wired together my own 24-volt battery, but for my current rig (a 4x4 truck, sometimes with a shell and roof tent, sometimes a full camper) I needed something more portable and more flexible. That's where Goal Zero's latest Yeti 1500 portable power station comes in. It's everything you need: battery, charge controller, and 2,000-watt inverter. It even has automatic power switching if you do have access to shore power.

The main appeal of power stations is that they're all-in-one, turnkey energy systems. You don't need to worry about hooking up inverters or monitoring systems—it's all there, ready to go. The downside to power stations is that most of them are less robust than DIY solutions, which is particularly important when overlanding or doing any off-road travel. Vibration is hard on plastic, and I've had several previous power stations eventually break down after a few years on the road. Plastic cracks, uncovered ports get clogged with dust; I've even had soldered connections come apart inside sealed batteries. (Thanks, washboard road into Chaco Canyon.)

Goal Zero's new Yeti 1500 power station is one of the best-built power stations I've tested. Unlike nearly everything else, the containing box is primarily metal (aluminum). There are still some plastic vent screens, but overall it's very tough and has stood up well to life in a vehicle. Additionally it was specifically designed to survive high-vibration environments, like living in your van or off-road vehicle. While I haven't taken it on the road into Chaco Canyon yet, it did spend two weeks in the back of my truck bouncing around dirt roads in New Mexico and Arizona and is no worse for the wear.

This is technically the sixth version of the Yeti 1500 and the first to use lithium iron phosphate (LiFePO4) chemistry for the battery, which is by far the biggest improvement over previous models. Older models used lithium polymer batteries. The difference is in the cathode materials. LiFePO4 uses lithium iron phosphate, while lithium polymer uses a variety of things, but usually nickel manganese or sometimes cobalt oxide. Don't worry if that means nothing to you. High school chemistry was a while ago for me too, but the upshot is that lithium iron phosphate has a longer cycle life (Goal Zero claims 4,000 charge cycles to 80 percent for the Yeti 1500), but slightly less energy density. LiFePO4 also performs better at both high and low temperatures, though it's worth noting the Yeti 1500 does not have a built-in heater and cannot be charged below freezing (a cheap heating pad can often overcome this, depending on your setup).

The Yeti 1500 offers a good selection of ports, split into three sections: AC power outlets, USB power outlets, and 12-V power outlets. The AC section gives you four plugs with a max continuous power of 2,000 W and surge capacity of 3,600 W. This was plenty to run a residential fridge during a power outage. The USB options include a 140-W charging port, 60-W port, two 30-W ports, and two 18-W USB-A ports. I charged everything from a brand-new Dell laptop to some camera batteries. I even charged an ancient iPod without issue. The 140-W port is plenty powerful enough to fast-charge your laptop and other high-wattage devices.

All those ports are fairly standard for a power station in this class, and similar to what was on the previous model—although the 140-W USB port is new and very nice to have. Where the new Yeti 1500 shines is the 12-V charging options, which include a high-power 12-V port capable of 30 amp output. That's enough for most van and overlanding vehicle power systems, meaning you can tie the Yeti 1500 directly to your house power 12-V distribution panel. There's also standard Anderson connector outputs and a cigarette-lighter-style outlet available.

There are three ways to charge the Yeti 1500. There's AC wall power, which can charge at up to 1,800 watts, getting you from 0 to 100 p
