Price truth

Capacity truth

The watt-hour number on the box isn't what reaches your devices. Same scale, three readings.

Rated (on the box)6,438 Wh

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

50% data
29

Usable capacity and how much you can run at once.

Capacity & expansion45% data
N/A

Usable watt-hours and how far you can grow it with add-on batteries, versus its size class.

Output & versatility70% data
29

Continuous and surge wattage, outlet count, and USB-C fast-charging.

Trust

37

Owner reputation, safety record, warranty, and build durability.

Trust & reliability34% data

Owner ratings, brand reputation, recall record, and warranty backing.

Durability & longevity80% data

Rated cycle life, warranty length, cell chemistry, and weather sealing.

Charging

Wall and solar recharge speed.

Charging & solar95% data
53

Wall recharge speed, solar input, and multi-source charging.

Livability

N/A

Lightweight, portable, and quiet enough to live with.

Portability
N/A

Weight, footprint, handle, and wheels, versus its size class.

Quiet / livability
N/A

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.

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

Rated cycle life
3,000 cycles

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).

Battery chemistry
Semi-solid-state

The type of battery cell. LiFePO4 (LFP) cells last far more cycles and are more thermally stable than older lithium-ion (NMC) cells.

Max capacity with expansion
64,000 Wh

The largest total capacity this unit can reach once you add every supported expansion battery.

Rated capacity
6,438 Wh

The battery's nameplate energy capacity — the headline number on the box. Real runtime comes from usable capacity and conversion losses, shown separately.

Cycle-life threshold
80 %

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.

Power output

Continuous power output
3,800 W

The most power you can draw at once, sustained — this has to be higher than the running wattage of whatever you're plugging in.

Surge power output
5,000 W

A brief power spike the unit can absorb when a device first switches on — matters for things with motors or compressors, like fridges.

Charging & solar

AC recharge speed
3,600 W

How fast the unit recharges from a wall outlet — higher means shorter waits between uses.

AC charge time (0–100%)
120 min

How long a full recharge takes from a wall outlet, start to finish.

Max solar input
3,000 W

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
0 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.

Aggregated from named outlets and marketplaces — we own no hardware and never fabricate impressions.

Trustpilot · brand3.1

Brand reputation: Whole-home flagship; semi-solid-state chemistry is a rare differentiator (energy density >228Wh/kg). 240V split-phase, 0ms UPS (US), 64kWh expansion. Trustpilot 3.1/813 mixed. Distinctive niche - low SERP competition.
