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 | Explorer 300D | Exodus 350 | What it means |
|---|---|---|---|
| Capacity | 288 Wh | 288 Wh | How much energy the unit stores. Sets how long everything else can run. |
| Continuous AC output | 300 W | 350 W | The largest load the inverter will run continuously, not counting surge. |
| Weight lower is better | 5.5 lb | 9.2 lb | The spec buyers most often regret ignoring. |
| List price lower is better | $209 | $299 | Vendor list price at the time of collection; street prices move. |
| Cost per watt-hour lower is better | $0.73 | $1.04 | Price divided by capacity. The fairest single value metric. |
| Watt-hours per pound | 52.4 Wh/lb | 31.3 Wh/lb | Capacity you get per pound carried. |
| Max solar input | — | 240 W | Caps how large an array is useful, and therefore off-grid recharge speed. |
| Rated cycles | 4,000 cycles | 4,000 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. |
| Warranty | 60 months | 60 months | Stated warranty length from the vendor listing. |
