A storm knocks the lights out and the phone battery starts its slow countdown. You search ecoflow delta 3 vs delta pro expecting two power stations, but here is what the listings actually hold: the delta 3 side has two genuine EcoFlow solar bundles, and the delta pro side holds a Gamo air rifle. Short verdict: shop the delta 3 side for backup power, because the delta pro side has no power station in it.

Detailed Review
The DELTA 3 MAX example pairs the station with a 220W bifacial solar panel and lists a 2,048Wh LFP battery, a 3400W X-Boost headline output, 0-80% charging in 1.13 hours and a transfer time under 10ms. The headline and the spec table disagree on output: the title says 3400W X-Boost while the spec table says 2400 watts output, 2400 starting and 3400 running; the title wins. A 5 year manufacturer warranty is stated.
Who it's for: a delta 3 shopper who wants the larger battery of the two bundles. Who should skip it: anyone who needs the quickest 0-80% charge; the Classic states 45 minutes.
Its Solar Score of 9.6/10 comes from performance 32/35, build 21/25, value 20/25, safety 0/10 and warranty 3/5: 76 of 100 points, placed on our 9.2 to 9.8 scale.

Gamo Swarm Magnum PRO 10X Air Rifle
A Gamo Swarm Magnum PRO 10X break-barrel air rifle with a 3-9x40 scope, listed here on the delta pro side.
Pros
- Listing is coherent as an air rifle
- 49.2 in length and 6.9 lb weight stated
- 3-9x40 scope included
- 5 year Manufacturer warranty stated
Cons
- Not a power station and states no power output
- Cannot be compared on battery, charging or UPS
- Its specs answer none of the comparison's questions
- Not comparable on any power-station criterion
Detailed Review
The delta-pro-side listing is the Gamo Swarm Magnum PRO 10X, a break-barrel air rifle with an IGT Mach 1 gas piston, a 3-9x40 scope, a 10-round magazine and 0.22 caliber, weighing 6.9 pounds. It is a coherent air rifle listing, and it states a 5 year Manufacturer warranty. It states no battery, no output and no charging figures, so it cannot be ranked against the two power stations on this article's criteria.
Who it's for: air rifle shoppers, elsewhere. Who should skip it: anyone comparing power stations.
Its Solar Score of 9.2/10 comes from performance 9/35, build 10/25, value 10/25, safety 0/10 and warranty 3/5: 32 of 100 points, placed on our 9.2 to 9.8 scale.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. Both EcoFlow listings state a 5-year manufacturer warranty, so they score on warranty; none states a safety listing, so all score zero on safety. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| EcoFlow DELTA 3 MAX with 220W Panel | 9.6 | 32 | 21 | 20 | 0 | 3 |
| EcoFlow DELTA 3 Classic with 110W Panel | 9.5 | 28 | 20 | 20 | 0 | 3 |
| Gamo Swarm Magnum PRO 10X Air Rifle | 9.2 | 9 | 10 | 10 | 0 | 3 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Capacity and output
The DELTA 3 MAX example lists 2,048Wh with a 3400W X-Boost output in its title, but its own spec table reads 2400 watts output, 2400 starting and 3400 running, so the headline and the table disagree; the title wins. The DELTA 3 Classic example lists 1024Wh with 1800W AC and 3600W surge, expanding to 2600W with X-Boost. Do not read the air rifle as an output figure: it is a rifle, and it states no power output at all. Solar generator vs gas generator frames the wider choice.
Charging and UPS
The DELTA 3 Classic example reaches 0-80% in 45 minutes with X-Stream AC charging, while the DELTA 3 MAX example needs 1.13 hours for the same stretch; both figures describe AC charging, so the Classic states the quicker charge. On solar, the Classic recharges in 11.6 hours with its 110W panel at a stated 23% conversion rate, and the MAX ships with a 220W bifacial panel without a stated recharge time. For backup, the Classic states a 10ms UPS and the MAX states a transfer time of less than 10ms. Best portable power station for cold weather covers outage-season picks.
The odd listing out
The delta-pro-side listing is the Gamo Swarm Magnum PRO 10X, a break-barrel air rifle with a gas piston, a 3-9×40 scope and a 10-round magazine. It lists 49.2 inches long, 6.9 pounds, 0.22 caliber. Nothing about it powers a refrigerator, and nothing about it can decide this comparison. It is featured because every listing is featured, and it finishes last because it is not a power station.
Sizing Notes
- Match the station to the load: the MAX example lists 2,048Wh and the Classic 1024Wh.
- Read the spec table against the title: the MAX example’s 2400W spec-table output and 3400W headline disagree.
- Keep panels and station together: the Classic ships with 110W, the MAX with 220W.
