Goal Zero Yeti 500 vs Allpowers R4000

Side-by-side on the specs that decide it — surge, capacity, runtime and price.

Both models' specs verified against manufacturer listings · Last updated July 29, 2026

The short answer

Goal Zero Yeti 500 costs $1600 less. Whether that gap is worth closing depends on what you need to run.

Allpowers R4000 holds 593% more energy (3456Wh vs 499Wh), so it runs the same load proportionally longer.
Allpowers R4000 has 5000W more surge headroom (6000W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
Goal Zero Yeti 500 is 93.1 lb lighter (12.9 lb vs 106 lb).
Goal Zero Yeti 500 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.

Goal Zero Yeti 500

A rugged, water-resistant unit for people who'll actually beat it up. You pay a premium over similar-capacity rivals for that durability.

Best for: Overlanders and job sites where the unit will get wet, dusty and knocked around.

Where it falls short:

$699 for 499Wh is expensive per watt-hour
Only a 2-year warranty vs 5 years from most rivals
120W solar input is very low

Allpowers R4000

A large expandable unit that undercuts the EcoFlow Delta Pro 3 on price while matching its 4,000W output — the trade is a less established support network.

Best for: Whole-home backup buyers prioritising price per watt over brand.

Where it falls short:

106 lb
