The short answer
Anker 535 PowerHouse costs $1170 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti Apex 300 holds 440% more energy (2764Wh vs 512Wh), so it runs the same load proportionally longer.
- Bluetti Apex 300 has 6930W more surge headroom (7680W vs 750W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 535 PowerHouse is 62.7 lb lighter (16.7 lb vs 79.4 lb).
- Bluetti Apex 300 is rated for 6,000 cycles vs 3,000 — meaningful if you cycle it daily.
Bluetti Apex 300
6000 cycles at 2764Wh — the best long-term cost-per-kWh in this list if you cycle daily. Bluetti's answer to the Elite 200 V2 at scale.
Best for: Off-grid solar setups where daily cycling makes lifespan the dominant cost.
Where it falls short:
- 79.4 lb
- Newer product with limited long-term field data
Anker 535 PowerHouse
A durable half-kWh unit for devices and light loads. Dependable, but the low output and slow charging make it a device-first companion.
Best for: Campers charging phones, laptops and lights, not appliances.
Where it falls short:
- 500W output is device-scale
- 120W solar input, slow recharge
