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	EB3A	RIVER 2	What it means
Capacity	268 Wh	243 Wh	How much energy the unit stores. Sets how long everything else can run.
Continuous AC output	600 W	300 W	The largest load the inverter will run continuously, not counting surge.
Weight lower is better	10.1 lb	7.7 lb	The spec buyers most often regret ignoring.
List price lower is better	$219	$219	Vendor list price at the time of collection; street prices move.
Cost per watt-hour lower is better	$0.82	$0.90	Price divided by capacity. The fairest single value metric.
Watt-hours per pound	26.5 Wh/lb	31.6 Wh/lb	Capacity you get per pound carried.
Max solar input	200 W	110 W	Caps how large an array is useful, and therefore off-grid recharge speed.
AC recharge time lower is better	—	60 min	Vendor-stated time to full from a wall outlet.
Rated cycles	2,500 cycles	3,000 cycles	Vendor claim for charge cycles before capacity degrades to 80%.
UPS switchover lower is better	—	30 ms	How long the unit takes to switch to battery. Under 20 ms keeps a desktop alive.
Warranty	24 months	60 months	Stated warranty length from the vendor listing.
