Verdict computed from this model's own tracked price history.
Capacity truth
The watt-hour number on the box isn't what reaches your devices. Same scale, three readings.
The marketing number — total cell capacity.

How it scores
Four buyer pillars over seven sub-scores — computed from sourced data with a published formula, price-independent by design.
Power
Usable capacity and how much you can run at once.
Usable watt-hours and how far you can grow it with add-on batteries, versus its size class.
Continuous and surge wattage, outlet count, and USB-C fast-charging.
Trust
est.Owner reputation, safety record, warranty, and build durability.
Owner ratings, brand reputation, recall record, and warranty backing.
Rated cycle life, warranty length, cell chemistry, and weather sealing.
Charging
est.Wall and solar recharge speed.
Wall recharge speed, solar input, and multi-source charging.
Livability
62% dataLightweight, portable, and quiet enough to live with.
Weight, footprint, handle, and wheels, versus its size class.
Fan noise under load — quieter is better for bedrooms and CPAP use.
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 | Weight |
|---|---|---|
| Power | Capacity & expansion + Output & versatility | 38% |
| Trust | Trust & reliability + Durability & longevity | 33% |
| Charging | Charging & solar | 16% |
| Livability | Portability + Quiet / livability | 13% |
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.

Capacity & battery
- Usable capacity
- 1,264.64 Wh
- Rated cycle life
- 4,000 cycles
- Battery chemistry
- LiFePO4
- Max capacity with expansion
- 5,000 Wh
- Rated capacity
- 1,264.64 Wh
- Cycle-life threshold
- 70 %
How much energy you can actually pull out of a full charge — the number that determines real runtime, not a marketing headline figure.
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. Real runtime comes from usable capacity and conversion losses, 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.

The most power you can draw at once, sustained — this has to be higher than the running wattage of whatever you're plugging in.
A brief power spike the unit can absorb when a device first switches on — matters for things with motors or compressors, like fridges.
How many standard wall-style outlets are built in.
How many USB-A ports are built in, for charging older phones, lights, and accessories.
How many USB-C ports are built in — check the per-port wattage below if you need fast charging for a laptop.
The fastest a single USB-C port can charge a device — relevant for laptops and fast-charging phones.
How many car-socket (cigarette-lighter) style 12V outputs are built in — what CPAPs and car fridges plug into for the most efficient overnight running.
How many round barrel-style DC outputs are built in, used by routers, some lights, and older electronics.
The most power the unit can deliver across ALL ports at the same time — can be lower than the AC rating plus every USB port added up.
Charging & solar
- AC charge time (0–100%)
- 102 min
- Max solar input
- 800 W
How long a full recharge takes from a wall outlet, start to finish.
The most solar panel wattage the unit can accept — undersized panels just mean slower charging, not damage, but oversizing this is wasted money.
Reliability & durability
- UPS switchover time
- 20 ms
How fast the unit takes over when grid power cuts out. Under ~20ms is fast enough that most electronics — including many CPAP machines — won't even blip.
Size & portability
- Weight
- 14.5 kg
How much the unit weighs on its own, without accessories — relevant for portability and carrying it up stairs during an outage.
What reviewers & owners report
Aggregated from named outlets and marketplaces — we own no hardware and never fabricate impressions.
- NA — no standalone unit listing on Amazon US (jackery.com reviews: 4.9/67, praise expandability, fast charge, LFP longevity) — Amazon reviewers
- modular expandability to 5kWh (standout at $999); long-life LFP; class-leading ~1.7h AC recharge; 2000W/4000W handles most loads; Wi-Fi/BT app with scheduling; rugged with impact corners — Across reviewers
- NA — no standalone Amazon listing (jackery.com reviewers note EPS-mode limits and weight) — Amazon reviewers
- heavier (~22-25 lb); MPPT/solar detail only in app not LCD; expansion packs pricey (~$399 ea); no wireless charging; EPS not a true online UPS — Across reviewers
- Wirecutter: none
- Popular Mechanics: none
- no major measurement-channel (Will Prowse/HoboTech/Project Farm) review found as of 2026-07-04 — YouTube reviewers
Brand reputation: Established 2023 model, generally strong reputation; jackery.com 4.9/67. One reviewer (backuppowerhub) claims it is discontinued in favor of the non-expandable 1000 v2 — but OEM product page remains live with current pricing as of 2026-07-04, so recorded discontinued=false with conflict noted
