How to Evaluate

The 6 Specs That Matter

Capacity (Wh)Fuel tank size. 1000Wh ÷ 100W device = ~10hrs (×0.85 for real world) Inverter (W)Running watts = continuous. Surge = motor startup spike (0.2s) ChemistryLiFePO4 = 3000+ cycles, 10yr life. NMC/Li-ion = 500 cycles, lighter UPS Switchover<10ms = NAS/PC safe. 20ms = OK. 30ms+ = will crash computers Charging Speed400W+ AC input = fast. 200W+ solar = usable off-grid Pure Sine WaveMust have for sensitive electronics. Modified sine = buzzing/damage

Price Benchmarks & Use Cases

$1.00/WhStandard (e.g. $500 for 500Wh) $0.67/WhGood value (e.g. $199 for 299Wh) $0.50/WhExcellent (e.g. $1000 for 2000Wh)
Use case guide:
• Camping (phones/laptops): 300-500Wh, 300-500W inverter
• Van life (mini-fridge/CPAP): 700-1000Wh, 1000W inverter
• Home backup (fridge/medical): 2000Wh+, 2000W+ inverter
• NAS UPS: 300Wh+, <10ms switchover, pure sine wave
⚠ Pure Sine Wave is NOT optional. Wirecutter requires it for all picks. Modified sine wave causes buzzing, overheating, and can damage sensitive electronics (NAS, CPAP, laptops). Every unit listed below has pure sine wave — if a unit doesn't explicitly state "pure sine wave", don't buy it.

Reality Check: Are the Claims Legit?

Weight Analysis

All models checked fall in the 58-98 Wh/kg range at system level, which is realistic for 2025 LiFePO4 cells:

  • OUKITEL P800E: 85.3 Wh/kg — plausible, uses prismatic cells
  • ALLPOWERS R600: 85.6 Wh/kg — plausible, compact design
  • EcoFlow Delta 2 Max: 89.1 Wh/kg — premium integration
  • Bluetti EB3A: 58.5 Wh/kg — conservative, uses cylindrical cells

Reference: Tesla Powerwall = 118 Wh/kg, Bluetti AC200P = 73 Wh/kg

Capacity Claims

All manufacturers quote cell-level rated capacity. Usable output is ~80-85% due to inverter losses. A "512Wh" station delivers ~410-435Wh to devices. This is normal industry-wide.

Red flag: Wh/kg > 120 at system level means fake capacity claims.

✓ All listed models pass the weight test

Output & UPS

Peak/surge ratings last 0.2-3 seconds. Continuous rating matters for sustained loads.

Verified <10ms UPS:

  • ALLPOWERS R600 — tested by BatterySkills
  • EcoFlow RIVER 3 Plus — EcoFlow official
  • OUKITEL P800E — official spec

Most others: 20-30ms (not NAS-safe)

💡 Gimmicks assessment: LED lights are genuinely useful for camping/emergencies (3-15W). Wireless charging is convenient but slow (15W max). App control is nice for monitoring. LCD screens are essential. Don't pay a big premium for extras — focus on the 6 core specs.

NAS UPS Compatibility

A NAS (Synology/QNAP) draws 20-60W (2-bay) or 40-100W (4-bay). For safe UPS operation:

  • Switchover time must be <10ms — 30ms will crash your NAS and corrupt data
  • Pure sine wave output required — NAS power supplies are sensitive to dirty power
  • Pass-through charging — unit stays plugged in, battery on standby
  • USB connection — some units support USB signaling to NAS for auto-shutdown

Runtime example: 300Wh × 0.85 ÷ 30W NAS = ~8.5 hours of backup

"9 times out of 10, the answer is no. Many power bank manufacturers advertise UPS backup but have auto-switchover times of 30 milliseconds or more. 30ms is more than long enough to damage connected devices permanently." — EcoFlow official blog
"We found its 10ms UPS switchover was genuinely instantaneous, preventing our work-from-home setup from even blinking." — BatterySkills review of ALLPOWERS R600
"EcoFlow RIVER 3 Plus is an affordable NAS-compliant UPS with a switchover time of less than 10 milliseconds." — EcoFlow official
