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 3 Plus | What it means |
|---|---|---|---|
| Capacity | 268 Wh | 286 Wh | How much energy the unit stores. Sets how long everything else can run. |
| Continuous AC output | 600 W | 600 W | The largest load the inverter will run continuously, not counting surge. |
| Weight lower is better | 10.1 lb | 10.4 lb | The spec buyers most often regret ignoring. |
| List price lower is better | $219 | $299 | Vendor list price at the time of collection; street prices move. |
| Cost per watt-hour lower is better | $0.82 | $1.05 | Price divided by capacity. The fairest single value metric. |
| Watt-hours per pound | 26.5 Wh/lb | 27.5 Wh/lb | Capacity you get per pound carried. |
| Max solar input | 200 W | 220 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 | — | 10 ms | How long the unit takes to switch to battery. Under 20 ms keeps a desktop alive. |
| Max expandable capacity | — | 858 Wh | How far the system can grow with add-on batteries. |
| Warranty | 24 months | 60 months | Stated warranty length from the vendor listing. |
