How we chose

We compared the five Yeti models on capacity, inverter output, chemistry, weight, warranty and current price, using the listed specs and the price gaps between them.

Capacity runs from 997 Wh on the Yeti 1000X to 6071 Wh on the Yeti 6000X, with the Yeti 1500X at 1516 Wh, the Yeti 3000X at 3032 Wh and the Yeti PRO 4000 at 3994 Wh. Four models use LI-ion NMC chemistry; the Yeti PRO 4000 uses LiFePO4. Weight tracks capacity, from 31.7 lb on the 1000X to 106 lb on the 6000X and 115.7 lb on the PRO 4000. The 1000X, 1500X, 3000X and 6000X carry a 2-year warranty and a 32-104 F operating range; the PRO 4000 carries a 5-year warranty and lists 4000 + lifecycles.

On price, the Yeti 1000X is the lowest entry at $999.95. The Yeti 1500X costs $124.94 more, the Yeti 3000X costs $2000.00 more, and the Yeti 6000X and Yeti PRO 4000 each cost $3000.00 more. The Yeti 6000X and Yeti PRO 4000 cost the same.

Who should skip these

Skip this family if you need a unit you can carry easily. Even the smallest here, the Yeti 1000X, weighs 31.7 lb, and the largest, the Yeti PRO 4000, weighs 115.7 lb. The Yeti 1500X is 45.6 lb, the Yeti 3000X is 69.8 lb, and the Yeti 6000X is 106 lb. These are units to set down and leave in place, not to move between rooms or load into a car without help.

Skip them too if you want a shorter recharge window than the listed 6-12 hour best-case solar charge. Every model in this family lists that same 6-12 Hours Charge figure for best-case solar, with 12-24 Hours Charge as the better-case figure and 25-50 Hours Charge as the good-case figure.

Price is another reason to look elsewhere. The range runs from $999.95 for the Yeti 1000X to $3999.95 for the Yeti 6000X and the Yeti PRO 4000. The Yeti 3000X costs $2000.00 more than the Yeti 1000X, and the Yeti 6000X and Yeti PRO 4000 cost $3000.00 more.

How to choose the right one

Start with capacity. The Yeti 1000X gives you 997 Wh, enough for phones, laptops and lights. The Yeti 1500X gives you 1516 Wh, which covers a small fridge or a router. If you need to run a refrigerator or other high-draw appliances, look at 3032 Wh and up: the Yeti 3000X at 3032 Wh, the Yeti 6000X at 6071 Wh, and the Yeti PRO 4000 at 3994 Wh.

Then check the 120V AC inverter rating. The Yeti 1000X lists 120VAC 60Hz 12-5A, while the Yeti 1500X, 3000X and 6000X list 120VAC 60Hz 16.5A. The Yeti PRO 4000 lists a pure sine wave inverter at 3600 W continuous, 7200 W surge, 120 V AC, 60 Hz, 30 A.

Chemistry matters too. The Yeti 1000X, 1500X, 3000X and 6000X use LI-ion NMC; the Yeti PRO 4000 uses LiFePO4. Warranty runs 2 years on the 1000X, 1500X, 3000X and 6000X, and 5 years on the PRO 4000. Current prices run from $999.95 for the 1000X to $3999.95 for the 6000X and PRO 4000.
