  • Solid packaging and included cables: XT60 for solar, XT60 car plug adapter, AC Euro plug to C19; manual in envelope

User experience / design notes

Pros

  • Ergonomics & usability:
    • Buttons to enable each port group (USB block, DC block, inverter outlets)
    • Inverter outlet section has physical safety covers/curtains
    • Inverter auto-off when lid is closed (to reduce battery drain)
  • Display is informative: shows percent charge, charging/discharging power, time estimates, cooling/overheat/timer indicators
  • Stable output quality:
    • Pure sine wave verified
    • Low ripple on USB
    • Low distortion under load

Cons / annoyances

  • Weight & size:
    • ~23.1 kg; “dragging up stairs is painful”
    • Big enough that it doesn’t fit the reviewer’s table/frame easily
  • Price: about $850 at the time of review
  • No wireless charging (reviewer notes some may be disappointed)
  • DC 12 V output current claim likely overstated: reviewer repeatedly states they did not achieve the stated 18 A on the DC sockets
  • USB-A fast charging limitation: must use at most two USB-A simultaneously for higher rates
  • Lid visor/covers interfere during bench testing (though removable)

Performance & test results (major outcomes)

1) USB charging behavior and quality

  • USB-C PD includes many protocols (PD3.0 up to 100 W on the main Type-C); PPS mentioned with smooth voltage changes.
  • USB-A fast charging:
    • Protocols: Apple 2.4A, Samsung AFC, Huawei FCP, Quick Charge 2/3
    • Reviewer says fast charging is limited by internal converters; only two USB-A ports at a time can fast-charge effectively.
  • Safety/protection:
    • Error 04 occurred during an overload scenario, but not the whole USB block—only affected the first USB-C port.
  • Ripple/voltage quality (oscilloscope results):
    • USB ripple measured as very low (examples: ~30 mV at 5V 3A; 67–80 mV at higher modes)
    • Reviewer calls it excellent and “safe for gadgets.”

2) 12 V DC outputs (car + 5525)

  • Reviewer measured ~12.3 V on all DC outlets and concluded they are paralleled.
  • Load tests:
    • At ~10 A / ~124–140 W, cooling kicks in and it behaves safely.
    • Around 150 W, DC module enters protection.
  • Ripple on DC outputs: also measured low (example mentioned up to ~62 mV), but the key issue remains:
    • Reviewer believes the manufacturer is hasty declaring 18 A, since practical sustained current wasn’t achieved.

3) Inverter (220 V) power, voltage stability, waveform

  • Output measured:
    • ~220 V AC (reviewer notes standard is often 230 V and says inverters should ideally provide headroom)
    • ~50 Hz
  • Waveform: confirmed pure sine wave
  • Power capability:
    • With a heater + dryer load escalation, station reached up to ~2.8 kW (over 2.4 kW claim) briefly, then overload icon appeared around that range.
    • Under heavy but controlled load (example: ~1700 W heater), it maintained ~220 V with inverter compensation and stable sine.
  • Noise/cooling:
    • At max power it was audible, but reviewer expected worse.
    • “Quite quiet” up to ~1 kW; cooling behavior acceptable.

4) Hard load challenges (tools)

  • Angle grinder (1300 W class):
    • Operated confidently; recorded max display power around ~1250 W (might have missed peaks due to wattmeter update limits).
  • Welding machine (100A-class):
    • Worked; reviewer could weld at test settings (110A+).
    • Overload icon appeared during welding (suggesting peaks near limits), but it still performed.

5) Battery capacity honesty (Wh measured)

  • Inverter discharge tests:
    • At ~4% cutoff protection, reviewer measured about 1816 Wh from inverter load (~92% of 2048 Wh).
    • At higher load mode, got ~1800 Wh.
  • Reviewer’s explanation for remaining capacity:
    • When charge drops to ~4%, inverter/DC module turn off, but USB/lamp may continue.
  • In “no-inverter” mode test (BL DC + USB + car outlet):
    • Drove station down from full to ~4%, then recharged; total delivered ~1935 Wh, about 95% of claimed capacity.
  • Overall conclusion: manufacturer’s capacity claim is essentially accurate, contrary to “divide watts by three” skeptics.

6) Charging speed (mains and external)

  • Mains charging: reviewer measured roughly ~1400 W input and ~1% battery per minute early on.
    • Estimated ~85% in 1.5 hours, then final-stage tapering.
    • Charged “60%” in about 1 hour (implied).
  • XT60 external charging limits:
    • XT60 can accept up to 500 W, requiring high voltage to reach max.
  • External battery recharging via XT60:
    • Using a 1280 Wh LiFePO4 battery as an input via XT60:
      • At ~12 V: peak around ~122 W
      • With series batteries (doubling voltage): peak around ~223 W
    • Reviewer conclusion: external battery charging works, but you can’t push huge recharging power through XT60; better for topping up than fast replenishing.

7) UPS switching demonstration

  • Reviewer intentionally lowered grid voltage (measured ~208 V instead of 230 V).
  • Results:
    • Station switches so outlet output remains stable (shows 220 V at outlets)
    • Switching observed as smooth/no load shedding on:
      • wattmeter + heater (~900 W)
      • higher load (~1400 W from grid scenario; remaining power used to charge station)
  • Conclusion: UPS functionality works in behavior—load continues while battery charges slowly, and switching is seamless if mains disappears.

Pros and cons (condensed)

Pros

  • Near-correct rated capacity (Wh delivered close to claim; inverter efficiency ~90%+)
  • Pure-sine 220 V inverter with excellent stability under load
  • Real overperformance margin: reached ~2.8 kW briefly vs 2.4 kW claim
  • UPS function confirmed operationally (seamless switching)
  • Excellent USB output ripple/quality and safe behavior with protection (partial shutdown on error)
  • Charging speed from mains is fast: reviewer measured ~1.4 kW input
  • Tool-friendly: grinder and welding work (with overload indication during peaks)

Cons

  • Expensive: about $850
  • Heavy/large: 23.1 kg; stairs are difficult
  • DC output current may not reach 18 A claimed (enters protection around lower power)
  • USB-A fast charging limited by converters: not all ports at full speed simultaneously
  • No wireless charging
  • Output sockets use protective shutters/curtains, less convenient for bench testing

Comparisons mentioned

  • Within the brand/model line:
    • AP1000 exists and is cheaper (~$530), but offers ~half capacity and up to 1.8 kW.
  • Against gasoline generator:
    • Reviewer argues buying a generator for similar money is impractical (noise, venting/exhaust in apartments)—no detailed technical comparison beyond that premise.

Overall verdict / recommendation

Recommended if you need

  • High backup power with a large ~2 kWh-class battery
  • a stable pure-sine 220 V inverter (tested up to ~2.8 kW short-term)
  • UPS-like seamless switching for appliances and tools

Not ideal if you

  • specifically need the promised 18 A DC current (reviewer doubts it’s achievable)
  • want ultra-portable equipment (it’s heavy)
  • expect a cheaper alternative to generators
