Capacity and battery

Capacity
2,048 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".

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.
160 Ah derived: 2,048 Wh nameplate ÷ 12.8 V = 160 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.

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.

This is the figure that decides which appliances it can run, like a 1,000 W microwave., AC, taken as non-stop, because the brand lists a separate Surge A short burst above the continuous rating, for appliances that need a kick to start, like a fridge compressor or a power tool.

With a Dometic CFX5 45 (example fridge), Middle estimate The answer with every figure the brands don't publish at its middle value: a test of that station where there is one, otherwise the typical result of tests on other stations. The range runs from every one of those figures at its least favourable end to every one at its most favourable. 4.7 days on the 12 V socket (range 4.2 to 5.1 days). Worked out with this station's own draw (measured by The Technology Man) and 12 V share (measured by The Technology Man). Runtime with your own fridge, solar and driving

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.
