Built like a toolbox, priced like it's 2021

Empty-to-full took 12.5 hours on the included 120W charger. The tester also saw the highest self-discharge of any power station he'd tested, a few percent over a month.

The two fans rarely came on in use; reviewer said it would run a CPAP overnight in silence.

The first review unit overheated and began malfunctioning after charging with the brick in the lid tray. Goal Zero suspected a faulty power brick and replaced it, and the replacement had no further problems.

What testers flag that the spec sheet does not
- Don't charge with the power brick sitting in the closed lid compartment. Off Grid Web's unit overheated that way.
- 500-cycle NMC battery. Fine for occasional outages, a poor fit for daily cycling.
- Budget for the $200 600W charger if you want recharges in hours rather than overnight.

Our take
Goal Zero more or less started this category, and the Yeti 1500X shows both sides of that. It's a sturdy aluminum-bodied 1,516Wh unit with a lid compartment for cables and the charger. PCWorld rarely heard its fans and measured 83% efficiency, about 1,267Wh, at a 200W load, dropping to 72% at 800W. Goal Zero also tells you to leave it plugged in, so it's always full when the power goes out. Most rivals tell you not to. The trouble is that the hardware has aged. It uses NMC cells rated for 500 cycles, where LFP competitors claim 3,000-4,000. The included 120W brick needs about 14 hours to refill it; the 600W charger that gets you to three hours costs extra. At $1,125 on Goal Zero's site, it's about $742 per kWh, close to double what the value leaders charge. Off Grid Web's first unit overheated and failed with what Goal Zero suspected was a bad power brick. The replacement worked fine. Goal Zero now sells an LFP 'NEW Yeti 1500' at $1,499.95, which is worth comparing before you buy this one.
✓ Strengths
- Rugged aluminum build and a lid compartment that stores the charger and cables
- Rarely runs its fans; PCWorld called it quiet enough for a CPAP at night
- Goal Zero says to leave it plugged in, so it sits at 100% waiting for an outage
✕ Trade-offs
- NMC chemistry rated for only 500 cycles, an eighth of what LFP rivals claim
- Included 120W brick takes about 14 hours to refill; the 600W charger is extra
- About $742/kWh, close to double the value leaders in our database
