Spec by spec

A green arrow marks the better figure on each row. Rows where only one unit publishes a number are shown without a winner rather than guessed.

Metric	S2000 Pro	FlashSpeed 2400	What it means
Capacity	1,451 Wh	1,408 Wh	How much energy the unit stores. Sets how long everything else can run.
Continuous AC output	2,400 W	2,400 W	The largest load the inverter will run continuously, not counting surge.
Weight lower is better	28.7 lb	41.9 lb	The spec buyers most often regret ignoring.
List price lower is better	$664	$699	Vendor list price at the time of collection; street prices move.
Cost per watt-hour lower is better	$0.46	$0.50	Price divided by capacity. The fairest single value metric.
Watt-hours per pound	50.6 Wh/lb	33.6 Wh/lb	Capacity you get per pound carried.
