How we chose

We started with capacity and output, then weighed those against battery chemistry and cycle life. The RIVER 3 Plus lists 286 Wh of LiFePO4 capacity rated to 3000 cycles to 80%, 600 W of output, under-10 ms UPS switching and 30 dB operation. The RIVER 2 Pro lists 768 Wh, and the RIVER 2 Max lists 512 Wh.

Then we looked at what each one costs today. The RIVER 3 Plus is $299.00, the RIVER 2 Pro is $379.00 and the RIVER 2 Max is $549.00. The gaps between them are just as relevant: the RIVER 2 Pro costs $80.00 more than the RIVER 3 Plus, the RIVER 2 Max costs $250.00 more than the RIVER 3 Plus, and the RIVER 2 Max costs $170.00 more than the RIVER 2 Pro.

For an entry-level station for CPAP, laptops and phones, that combination is what settled it. The RIVER 3 Plus carries the chemistry and cycle rating we wanted at the lowest of the three prices, while the RIVER 2 Pro is the pick when capacity is the priority and the RIVER 2 Max is for those who specifically want 512 Wh.

Who should skip these

If you need more than 600 W of output or well over 768 Wh of capacity, these aren't the right fit. The RIVER 3 Plus tops out at 600 W and 286 Wh, the RIVER 2 Pro at 768 Wh, and the RIVER 2 Max at 512 Wh. For bigger loads or longer runs, a larger station makes more sense.

The RIVER 3 Plus is the smallest of the three at 286 Wh, so it suits CPAP, laptops and phones rather than heavy appliances. The RIVER 2 Max sits at 512 Wh for $549.00, which is $250.00 more than the RIVER 3 Plus at $299.00. If you want the most capacity here, the RIVER 2 Pro gives 768 Wh for $379.00, $80.00 more than the RIVER 3 Plus and $170.00 less than the RIVER 2 Max.

All three are at their 90-day low: $299.00, $379.00 and $549.00. If none of those capacities or that 600 W ceiling covers what you need to run, look at larger stations instead.

How to choose the right one

Start with the load, not the label. Add up what you need to run overnight — a CPAP, a laptop, phones — and compare that to the capacity of each unit. The RIVER 3 Plus gives you 286 Wh, the RIVER 2 Max gives you 512 Wh, and the RIVER 2 Pro gives you 768 Wh. If your overnight draw is modest, the smaller unit covers it; if you run more devices or want more headroom, the larger capacities are the reason to step up.

Then weigh size against capacity. The RIVER 3 Plus is the lightest of the three at 10.4 lb and measures 9.2×9.1×5.8 in, with 600 W output, under-10 ms UPS switching and 30 dB operation. It uses LiFePO4 rated to 3000 cycles to 80% capacity. If you would rather carry less and your load is light, that is the trade.

On price, the RIVER 3 Plus is $299.00, the RIVER 2 Pro is $379.00, and the RIVER 2 Max is $549.00. The RIVER 2 Pro costs $80.00 more than the RIVER 3 Plus; the RIVER 2 Max costs $250.00 more than the RIVER 3 Plus and $170.00 more than the RIVER 2 Pro. Choose the RIVER 2 Max only if you specifically want 512 Wh.
