Metric	JuiceGo 240 (modified sine)	FlashSpeed 300	What it means
Capacity	240 Wh	230 Wh	How much energy the unit stores. Sets how long everything else can run.
Continuous AC output	150 W	300 W	The largest load the inverter will run continuously, not counting surge.
Weight lower is better	6.3 lb	7.4 lb	The spec buyers most often regret ignoring.
List price lower is better	$136	$270	Vendor list price at the time of collection; street prices move.
