How we score
Correction · October 2026
This Award Was Re-Scored — and the Winner Changed
This award was first given to the Anker SOLIX C300 DC with a published 91/100. An October audit found three problems: the C300 DC was scored as if it had a 300W AC outlet (it is DC-only, with no AC outlet at all); the EcoFlow River 3 Plus was scored on the wrong output, weight and solar figures; and the published 91 did not match the page's own weights. We corrected the specs, replaced hand-assigned dimension scores with the fixed formulas below, and re-ran every eligible unit. The C300 DC remains a strong DC power bank for its price — it simply cannot run AC devices, and the scoring now reflects that.

The value score used the mean of each product's logged Amazon prices up to the scoring date; the “price now” column is live and can differ.
Exactly How Each Dimension Is Scored
Capacity & Power Output · 20 points
Half capacity (Wh) and half continuous AC output, each relative to the best in the field. A unit with no AC outlet scores 0 on the output half.
Value for Money · 30 points
Watt-hours per dollar at the mean of our logged Amazon prices, relative to the best in the field.
Solar Charging · 10 points
Maximum solar input, relative to the best in the field.
Portability · 10 points
Watt-hours per pound, relative to the best in the field.
Expandability & Feature Set · 15 points
Equal thirds for three verifiable features: accepts expansion batteries; UPS switchover (full marks at 10 ms or faster, two-thirds at 20 ms); companion app. A feature counts only when two or more independent sources confirm it.
Battery Chemistry · 15 points
100 when LiFePO4 is confirmed on the manufacturer's spec sheet; 75 when it appears only on a retail listing.
Capacity, output, solar input and weight come from our product database, where each spec is checked against two or more sources. The six weights are the budget-category weights from our scoring methodology, with Value weighted highest.
Why the EcoFlow River 3 Plus Won — and How Close It Was
The River 3 Plus does not lead on price or weight — the Anker C300 DC takes both of those dimensions. It wins because it is the only budget unit that combines 600W of AC output, the highest solar input in the group (220W), a sub-10 ms UPS mode, a companion app, and the ability to add an extra battery later. That breadth outweighs a lower value score.
The margin is narrow. The Bluetti Elite 30 V2 trails by 2.5 points: it matches the River's output, has a 10 ms UPS and an app, costs less and is lighter — but it cannot be expanded. We tested how sensitive the result is to our formula choices:
- •Using the September price snapshot, the October snapshot, or their mean: the River 3 Plus wins in all three when the three features are weighted equally.
- •If expandability were weighted at a fifth or less of the features dimension, the Elite 30 V2 could win instead (it does at the September prices with a one-fifth weighting, and at every price snapshot with zero). We kept expandability as a full third because it is in the dimension's name and is the one capability that changes what you can do with the unit next year.
- •The Anker C300 DC finished third under every combination we tried — its lack of an AC outlet costs it too much on output and features for its value lead to overcome.
Which Budget Unit Is Right for You
EcoFlow River 3 Plus · 87.0
Buy it if you want the most capable all-rounder under $500, a desk UPS, or the option to add a battery later.
Bluetti Elite 30 V2 · 84.6
Buy it if you want 600W of AC and a 10 ms UPS for less money and a little less weight, and will never need more than 288 Wh.
Anker SOLIX C300 DC · 69.4
Buy it if you only charge USB-C laptops, phones, cameras and 12V gear, and want the lightest, cheapest option. It has no AC outlet.
EcoFlow River 3 · 66.5
Buy it if you want the smallest EcoFlow for phones, a router and lights, and do not need more than 300W.
Jackery Explorer 300 · 64.6
Buy it if you want a simple small Jackery with two AC outlets for phones, lights and a CPAP night.
Need more than 300 Wh? A 1 kWh unit is the next step — see the Best Under $1,000 award and our under-$500 buying guide.
Frequently Asked Questions
Why did the EcoFlow River 3 Plus win Best Budget 2026?
It scored 87.0/100 on our fixed budget-category formulas: it is the only budget unit combining 600W of AC output, the group's highest solar input, a sub-10 ms UPS, an app and expandability. The Bluetti Elite 30 V2 was a close second at 84.6.
Why did the Anker SOLIX C300 DC lose the award?
It was originally scored as if it had a 300W AC outlet. It is DC-only, with no AC outlet. Re-scored on its real specs with the same formulas, it finished third: it leads the group on value and on energy per pound, but scores zero on AC output and on the verified features.
How was the score calculated?
Six dimensions are scored by fixed formulas: capacity and AC output, watt-hours per dollar at logged Amazon prices, solar input, watt-hours per pound, three verified features in equal thirds, and battery chemistry. Each is weighted by the budget-category weights (Value 30, Power 20, Features 15, Battery 15, Solar 10, Portability 10).
Would the result change with different prices?
Not with the price data we have. The River 3 Plus wins using the September price snapshot, the October snapshot, or their mean. It could lose to the Bluetti Elite 30 V2 if expandability were weighted at a fifth or less of the features dimension.
What can a 300 Wh budget solar generator power?
Phones, laptops, LED lights, a router and a CPAP for about a night. With a 600W outlet, as on the River 3 Plus and Elite 30 V2, it can also run small AC appliances briefly. It will not run a refrigerator overnight; that takes a 1 kWh unit.
