Goal Zero Yeti 1500X (NMC, SKU 36300)

The Yeti 1500X (SKU 36300) is Goal Zero's older 1,516 Wh station, still on sale alongside the newer Yeti 1500 (SKU 37300). Read listings carefully: the names differ by one letter, but the batteries differ in kind. The 1500X uses NMC cells rated for 500 cycles to 80 % capacity (1C, full charge and discharge, 25 °C); the new Yeti 1500 uses LiFePO4 rated for 4,000 cycles to the same 80 %. Because both count to 80 %, the two figures compare directly (how makers define cycle life).

The numbers that decide backup use

Goal Zero rates 2,000 W continuous and 3,500 W surge from two AC outlets. That starts the top-freezer refrigerator (1,200 W) and the 1/2 HP sump pump (2,150 W). The circular saw's 3,600 W start is just above the surge rating.

Using the 0.85 factor explained on the methodology page, 1,516 Wh × 0.85 ÷ 47 W gives about 27.4 hours for the top-freezer refrigerator at its yearly-average draw.

Charging is the weak point

The 1500X has no built-in wall charger. With the included 120 W power supply a full charge takes 14 hours; with the optional 600 W supply, 3 hours. Solar input is up to 600 W. Operating temperature is 32–104 °F, without a separate charge range — so a cold garage below freezing is outside the published range.

The page contradicts itself on expansion: one block says "Chainable: With Yeti Link and Tank Expansion batteries", the general block says "Chainable: No". No UPS switch-over time is published. Warranty is 2 years.

Frequently asked questions

Is the Yeti 1500X LiFePO4?

No. Goal Zero lists "Li-ion NMC", rated for 500 cycles to 80 % capacity. The newer Yeti 1500 is the LiFePO4 model.

How long does it take to charge from the wall?

14 hours with the included 120 W power supply, or 3 hours with the optional 600 W supply, per Goal Zero.

Can it run a refrigerator?

On the published numbers, yes: the top-freezer refrigerator needs 360 W running and 1,200 W to start. At its 47 W yearly average, 1,516 Wh × 0.85 ÷ 47 W gives about 27.4 hours.

Can it be used in freezing temperatures?

Goal Zero gives an operating range of 32–104 °F, so below freezing is outside its published range.

What warranty does it have?

2 years, per Goal Zero. The newer Yeti 1500 lists 5 years.
