Capacity and battery

Capacity
3,600 Wh (Nameplate capacity The capacity printed on the box, in watt-hours (Wh): what the battery holds when new. You get less out of it in use, because the station keeps some back to protect the battery and loses some turning it into 240 V or 12 V power., Usable capacity How much of the box capacity you can actually draw out. Most brands don't publish it, so the box figure is the only one that can be compared. not stated)

Battery type The type of cells inside the battery. Most power stations now use LiFePO4; NCM, short for nickel cobalt manganese, is the other type that turns up.
LiFePO4 Lithium iron phosphate, the battery type most power stations now use. Battery boxes sometimes call it "lithium".

Cycle life How many full charges before the battery drops to a set share of its original capacity, usually 70% or 80%. 4,000 cycles to 80% is a higher bar than 4,000 cycles to 70%. The table's column counts cycles to 80% only.
3,500 cycles (until 80% of the original capacity is left (also stated: 6,500 cycles to 50%))

Ah at 12.8 V Capacity in amp-hours, the way a 12 V lithium battery box states it, so the two can be compared. Worked out from the Wh figure: Wh ÷ 12.8.
281.3 Ah derived: 3,600 Wh nameplate ÷ 12.8 V = 281.3 Ah
Price per Wh The price divided by the capacity on the box, in cents (¢) per watt-hour (Wh). Lower means more capacity for the money.
79.1¢ derived: $2,849 (price today) ÷ 3,600 Wh nameplate = 79.1¢ per Wh

Output

AC output The household-style power points on the station, for things you'd normally plug into a wall. The figure is the continuous rating in watts (W): the most the station can supply non-stop.

The range runs from every one of those figures at its least favourable end to every one at its most favourable. 4.5 days on the 240 V outlet, as no 12 V socket is stated (range 3.2 to 6.4 days).

Capacity is the nameplate figure in watt-hours (Wh), the one on the box. AC output is the power a station can supply non-stop, not a short burst. Weight is the station on its own. A figure measured another way is shown with a note saying how, and isn't compared with the others.
