Model comparison
Two compact LiFePO4 units under 300 Wh with 600 W outlets. The Elite 30 V2 is the cheaper energy, 11% less per watt-hour at the makers' prices. The RIVER 3 Plus refills from the wall in 1 hour against 1 hour 10 minutes and takes an extra battery: buy it for that, and the Elite 30 V2 for the money.
BLUETTI
$249.99 $279.99 at BLUETTI
Buy it if you want the most stored energy per dollar ($0.87 against $0.98 per Wh).
EcoFlow
$279 $299 at EcoFlow
Buy it if you need a higher solar input ceiling (220 W against 200 W); actual recharge depends on the panels.

Cycle counts are highlighted only when both makers rate them to the same remaining capacity. A full recharge is not ranked against a charge to 80%. Missing figures never count as an advantage. These are manufacturer ratings; matching endpoints do not prove identical test conditions.
Rated cycles: Elite 30 V2, 3,000 to 80%; RIVER 3 Plus, 3,000 to 80%.

Estimated AC energy = rated Wh × 0.85. Runtime = estimated AC energy ÷ load W, with no reserve. Capacity and weight differences use the displayed figures; price per Wh uses each model's own price record and date. Device-load inputs are in the sizing calculator.
Check whether each unit has enough battery and output for the devices you want to run.
| Job | Needs | Elite 30 V2 | RIVER 3 Plus |

| a day of home backup (a full-size refrigerator, a router, phones and lights for a day) | 2,323 Wh, 92 W running, 1,351 W start | no: too little capacity | no: too little capacity |
| a night of CPAP (a CPAP with its humidifier for one 8-hour night) | 599 Wh, 53 W running, 104 W start | no: too little capacity | no: too little capacity |
| two nights of camping (a compressor cooler, lights, phones, a laptop and a fan for two nights) | 2,066 Wh, 157 W running, 157 W start | no: too little capacity | no: too little capacity |
| a day in an RV (a 12 V fridge, lights, TV, coffee maker, phones and a laptop for a day) | 648 Wh, 156 W running, 156 W start | no: too little capacity | no: too little capacity |

| a laptop and two phones (a laptop for six hours and two phone charges) | 396 Wh, 60 W running, 60 W start | no: too little capacity | no: too little capacity |
Hours = capacity × 0.85 ÷ device watts, with the draws from the device table; "start" is whether the inverter's surge clears the device.

|---|---|---|---|---|---|

| Laptop (MacBook Air, charging) | 40 | 6.1 | yes | 6.1 | yes |
| Wi-Fi router | 24 | 10.2 | yes | 10.1 | yes |
| Starlink Standard kit (dish + router) | 88 | 2.8 | yes | 2.8 | yes |

BLUETTI Elite 30 V2 states a 10 ms switchover, so it can sit between the wall and a fridge, router or CPAP and take over when the power cuts; EcoFlow RIVER 3 Plus states 10 ms. BLUETTI Elite 30 V2 holds more (288 against 286). Check your appliance's start-up watts against the surge figures in the table.
Elite 30 V2 at $0.87 per Wh against $0.98. This compares purchase price with rated capacity, not lifetime delivered energy.
A small window unit draws 500 to 1,000 W running and several times that for an instant at start; check the surge figure in the table against the air conditioner's label. Either way an afternoon of it empties a 1 kWh unit; the RV page works the rooftop version.
