Capacity truth

What it can run
Same sourced device assumptions used by our calculators, applied to this model's usable AC energy. Actual runtime varies with load, temperature, and standby draw.
| Device | Estimated runtime | Sourced assumption |
|---|---|---|
| CPAP (humidifier off) | about 40.8 nights | 9 W · |
| CPAP (heated humidifier on) | about 6.6 nights | 56 W · |
| Refrigerator (full-size) | about 47 hours | 180 W × 35% duty cycle · |
| Wi-Fi router + modem | about 163 hours | 18 W · |
| Laptop (65W charger) | about 90 hours | 65 W × 50% duty cycle · |
| Phone (one full charge) | about 146 full charges | 20 W · |
Who it fits
Mechanical matches against this model's own sourced specs — never invented sentiment, never a guess on a spec we don't have.
2938 Wh AC-delivered (est.) → multiple CPAP nights per charge
3600 W inverter, 2938 Wh AC-delivered (est.) → runs a fridge through an outage
3840 Wh, expandable, 12V DC out → long off-grid stays
How it scores

How this score is computed
The BatteryRank score is computed from sourced data with a published formula — ranked by data, not lab testing. Seven sub-scores blend into a 0–100 composite, grouped into four buyer pillars. Price is deliberately not a scoring input: prices move daily, so value intelligence lives in the price section above, judged against this model's own history.
| Pillar | Built from |
|---|---|
| Power | Capacity & expansion + Output & versatility |
| Trust | Trust & reliability + Durability & longevity |
| Charging | Charging & solar |
| Livability | Portability + Quiet / livability |
Scores are cohort-relative — each model is ranked against others in its size class. Missing inputs renormalize out rather than scoring zero (a model is never penalized for a spec nobody in its class publishes), and any figure resting on a documented estimate is tagged est.

How many full charge-and-drain cycles before the battery drops to its rated threshold (shown alongside — brands rate to different thresholds, so never compare bare cycle counts).
The type of battery cell. LiFePO4 (LFP) cells last far more cycles and are more thermally stable than older lithium-ion (NMC) cells.
The largest total capacity this unit can reach once you add every supported expansion battery.
The battery's nameplate energy capacity — the headline number on the box. Battery-side usable and AC-delivered capacity are shown separately.
The remaining-capacity level the cycle rating is measured to. 3,000 cycles to 80% is a stronger battery than 3,000 cycles to 70% — always read the two numbers together.

Quick answers
Each answer restates a sourced figure from elsewhere on this page — nothing new, nothing guessed.
- How much does the Aferiy P310 weigh?
- 42 kg (92.6 lb), manufacturer-claimed, without accessories.
- What are the dimensions of the Aferiy P310?
- 584 × 321 × 464 mm (23 × 12.6 × 18.3 in), length × width × height, manufacturer-claimed.
- How much capacity does the Aferiy P310 deliver through an AC outlet?
- About 2,938 Wh of the rated 3,840 Wh reaches an AC outlet from a full charge — an estimate after our published 15% inverter-loss constant (marked est. on this page).
- How many watts can the Aferiy P310 output?
- 3,600 W continuous AC output and 7,200 W surge output, manufacturer-claimed. Appliance startup demand must stay within the relevant limit.
- How much solar input can the Aferiy P310 accept?
- 2,000 W maximum solar input, manufacturer-claimed. Actual harvest depends on panel compatibility, sun, orientation, temperature, and conversion losses.
- What is the cycle-life rating of the Aferiy P310?
- 4,000 cycles to 85% remaining capacity, manufacturer-claimed. A cycle rating is not a calendar-life guarantee.
- Can the Aferiy P310 work as a UPS?
- Its manufacturer-claimed transfer time is 10 ms. Confirm that your connected equipment tolerates that transfer time; this is not the same as a zero-transfer online UPS.
- How far can the Aferiy P310 expand?
- Up to 11,520 Wh with compatible expansion hardware, manufacturer-claimed. The base-unit capacity and expansion-system capacity are shown separately.
