Sitolity AP2000 (Budget power station) — Key points from the review

What it is / positioning

  • The Sitolity AP2000 is positioned as a budget underdog power station.
  • It was reviewed in a shootout against:
    • EcoFlow Delta 2 Max
    • Anker F2000
    • Oops (spelled “oops Exodus” in the subtitles)
  • Target class (as described): each unit is said to have ~2 kWh battery capacity and a ~2400 W pure sine wave inverter.

Main features mentioned

Battery / inverter

  • Battery rating: 2048 Wh (2.048 kWh)
  • Inverter rating: 2400 W (pure sine wave stated for the class)
  • Battery chemistry: LiFePO4 (lithium iron phosphate)

Solar / DC input

The review notes conflicting label specifications:

  • Unit sticker printed: 12–48 V
  • In-video spec: 12–60 V, 800 W max
  • Brand clarification (later):
    • Correct spec: 12–60 V (max 800 W)
    • 12–48 V was an older label due to a protection oversight

Ports/cables mentioned:

  • DC input (shown initially on-screen/spec label): 12 to 48 V (later corrected by brand email)
  • 12 V cigarette-style plug
  • Two barrel plugs
  • Solar includes a cable: MC4 to XT60

AC charging cable

  • Includes a “heavy duty” AC charging cable.

AC outputs / screen

  • The screen displays:
    • Input power
    • Output power
    • Estimated time remaining (for input/output)

USB / PD

  • Four Quick Charge type-A ports
  • USB-PD ports: 25 W and 100 W

Other controls / behavior

  • Sleep/shutdown behavior described:
    • AC button press patterns for on/off
    • Automatic shutdown after ~30 minutes of light load
    • Ability to cancel auto shutdown when the AC icon is flashing

Pros (what worked well)

Good capacity extraction vs rating

Despite confusing SOC display behavior, the reviewer reports strong real-world draw:

  • First capacity test: 1,690 Wh measured from 2,048 Wh rated (~82%)
  • Second test: about 1.67 kWh, with similar behavior
  • Reviewer conclusion: it likely pulled “full capacity” even though the display suggested otherwise (e.g., showing 11%).

Overload/maximum-power handling (more conservative than some)

  • Under heavy load, the AP2000 reduced output voltage automatically instead of immediately collapsing/shutting down.
  • Reviewer preferred shutdown over sag, but noted it did not crash as dramatically as some competitors.

Surge start performance (washer/dryer test)

  • Gas dryer start (surge load): “struggled, but it started,” which the reviewer views as impressive for the class.
  • Washer + dryer together: drew only about ~400 W, suggesting multiple batches/cycles may be feasible after startup.

Value

  • Reviewer states the AP2000 can be significantly cheaper than at least EcoFlow and Anker, and potentially competitive with Oops during sales.

Cons / problems (biggest issues)

1) SOC display and shutdown at “too high” a percentage

  • During AC capacity testing, the inverter shut down while the display still showed ~11% remaining.
  • After re-enabling, the inverter would not start again (though USB ports still worked).
  • After additional tests, shutdown improved only slightly:
    • After recalibration attempt: shut off at 9% instead of 11%
  • Brand claim:
    • With proper full calibration cycles, shutdown should occur around ~5%
    • Reviewer didn’t continue the full process due to time constraints

Brand explanation (from email)

  • Not considered a defect; described as normal behavior due to battery calibration.
  • Cause: LiFePO4 cells had a longer storage/transport period causing a voltage dip and temporary misalignment between BMS SOC reading and actual cell voltage.

Protection logic described:

  • Outputs shut off when:
    • SOC < ~5%, or
    • any single cell drops below 3 V
  • In the reviewer’s unit, the cell-voltage threshold triggered first while SOC still read 11%.

Fix suggested:

  • Run 1–2 full charge/discharge cycles:
    • Discharge fully using USB charging until all outputs turn off
    • Then charge uninterrupted to 100%

Reviewer verdict:

  • SOC indicator may be misleading if you expect AC to shut off right at “0%”.

2) Voltage sag behavior under heavy load

  • When pushed hard, AP2000 lowered voltage automatically rather than shutting down immediately.
  • Reviewer dislikes this because it could harm sensitive electronics.
  • Reviewer would rather it shut down when exceeding max inverter limits.

3) Design annoyances / connectivity

  • Outlet door: visually sleek but inconvenient:
    • Blocks access while plugging in (camera/ergonomics concern noted)
  • Reviewer also wants a more standard AC plug type (current one is less commonly available).

4) UPS mode failure (as tested with a gaming PC)

  • Reviewer reports UPS mode did not work with their high-end gaming PC workstation.
  • The system randomly shut off under only light desktop workload.
  • Reviewer hopes it didn’t damage the PC, but overall results were negative.

Performance comparisons from the shootout

Heavy load / inverter limit tests (heat gun + space heater)

  • AP2000:
    • Held roughly a ~2400 W range after exceeding (with voltage sag/adjustment occurring)
    • Reviewer disliked automatic voltage lowering but viewed it as preferable to some alternatives
  • Anker F2000:
    • Voltage sagged dramatically to ~81 V, then it either shut down or behaved inconsistently
    • First attempt felt “very strange,” then shutdown on repeated attempts
  • Oops:
    • Seemed to operate very near max output (“sweet spot”)
    • Slight sag, but when the heater was set higher, it immediately shut down
  • EcoFlow Delta 2 Max:
    • Survived up to the “cusp”
    • Could go high/near max but then shut off immediately at higher heat (overload sign mentioned)

Surge load (dryer start)

  • AP2000 was among the few that could start the dryer in this class.

Loudness / fan noise (experiential)

  • Oops: described as loudest by a long shot (“fans crazy loud”)
  • Anker: next loudest
  • AP2000: then
  • EcoFlow Delta 2 Max: quietest

Ratings / numbers included

  • Battery rating: 2048 Wh
  • Inverter rating: 2400 W
  • Solar input (corrected by brand): 12–60 V max 800 W
  • Measured capacity extraction:
    • ~1,690 Wh (~82%) in first AC capacity test
    • Second test: ~1.67 kWh
  • Shutdown/SOC behavior:
    • First observed AC shutdown at 11%
    • Later improved shutdown at 9%
    • Brand claims intended protection shutdown around ~5%
  • UPS test: failed in reviewer’s setup (no numeric score given)

Unique points mentioned (complete list)

  1. Shootout premise vs “giants” in the ~2 kWh / ~2400 W class.
  2. Included cables: 12V to XT60, MC4 to XT60, and heavy-duty AC charging cable.
  3. Minimal/cool design; screen shows input/output and time remaining.
  4. Shutdown/sleep/manual control notes (AC press patterns; auto shutdown after 30 minutes of light load; cancel option).
  5. SOC issues: inverter shut down at 11% then 9% with AC; inverter wouldn’t restart while USB still worked.
  6. Capacity testing results: ~1.69 kWh and ~1.67 kWh vs 2048 Wh rated.
  7. Solar/DC label discrepancy (12–48 V vs 12–60 V), corrected by brand email.
  8. Brand explanation: LiFePO4 storage/transport voltage dip caused temporary SOC/BMS misalignment.
  9. Brand protection logic: shut off under SOC < 5% or cell < 3 V; suggested recalibration cycles.
  10. Heavy-load testing using heat gun + space heater; voltage behavior when exceeding limits.
  11. Comparison across AP2000 vs Anker vs Oops vs EcoFlow during max-load tests.
  12. Criticism: AP2000 lowering voltage automatically under high load could affect sensitive electronics.
  13. Surge start test: dryer start succeeded but with struggle.
  14. Washer + dryer together only drew ~400 W (suggesting multiple batches likely feasible).
  15. UPS test: random shutoff; UPS mode did not work for the reviewer’s gaming PC workstation.
  16. Price/value claim: AP2000 is significantly cheaper than some competitors; Oops may be close during sales.
  17. Loudness ranking: Oops loudest, Anker next, AP2000 next, EcoFlow quietest.
  18. Mechanical/UX issue: outlet door inconvenient; reviewer also had a door tab break but liked the easier access after.
  19. Reviewer wishlist: 120V inverter, avoid door blocking, avoid voltage drop (prefer shutdown), standard AC plug type, better SOC calibration so AC shuts off at true “0%”.

Speakers/views

  • Single main reviewer voice (with occasional laughter from another person).
  • No separate technical experts; most tests and technical claims come from the reviewer.
  • Extra voice mostly reacts during banter and adds no technical information.

Overall verdict / recommendation

The Sitolity AP2000 is presented as a good value budget option that can handle real loads (including starting a dryer) and performs competitively in its class.

However, the review highlights two major usability/reliability concerns:

  1. Misleading SOC display causing AC shutdown to occur early (likely fixable with full recalibration cycles).
  2. UPS mode failing for the reviewer’s gaming PC setup, plus some voltage-sag behavior under heavy overload.

Recommendation

  • Buy if you want a cheaper ~2 kWh / 2400 W power station for general off-grid power and surge loads—and you’re willing to verify calibration/behavior.
  • Avoid for UPS/gaming PC power backup based on this test, especially if you need stable voltage under overload for sensitive electronics.
