Metric	RIVER 3 Plus	Explorer 300D	What it means
Capacity	286 Wh	288 Wh	How much energy the unit stores. Sets how long everything else can run.

Weight lower is better	10.4 lb	5.5 lb	The spec buyers most often regret ignoring.
List price lower is better	$299	$209	Vendor list price at the time of collection; street prices move.
