A Clash of Solar Power Station Titans
Bluetti’s AC200P and EcoFlow’s Delta are some of the most popular solar generators on the planet and for good reason, too! They’re mighty powerful, super portable, feature-rich, user-friendly, and they look great — are we spoiled for choice, or what?
But therein lies the crux of the matter. Which of these amazing power stations should you choose? Well, that’s exactly what I’m going to help you out with today!

Portability
Weighing in at 60.6 lbs and measuring 16.5 x 11 x 15.2”, the Bluetti AC200P is decidedly bulkier than the EcoFlow Delta, like… a lot bulkier! At 30.864 lbs, the Delta is half the AC200P’s weight and measures a modest 15.7 x 8.3 x 10.6”.
So, in terms of pure portability, the EcoFlow definitely has the edge, but that’s not to say that the Bluetti is overly cumbersome. Sure, it’s quite heavy, but the handles are durable and ergonomic, so when the time comes to heave-ho and set up camp, I personally don’t find it all that much of a challenge, and I have what the gym community would refer to as noodle arms.
Verdict
It’s the EcoFlow Delta all the way!
Battery Power & Capacity
Bringing a whopping 2000 continuous and 4800 surge watts of power to the equation, the AC200P is certainly no pushover. If you’re wondering what that means in real-life terms, it’s enough clout to power some pretty demanding power tools — we’re talking circular saws and rotary hammers.
The EcoFlow Delta, on the other hand, tops out at 1800 continuous watts and 3300 surge watts. Now, don’t get me wrong, that’s still some serious oomph.
This thing is capable of powering tons of energy-hogging appliances such as small to medium refrigerators, washing machines, coffee makers, and fairly large TVs, but the AC200P definitely has more muscle, and the gap between these units only widens when you factor in capacity.
The AC200P is rated for a very impressive 2000 Wh, while the Delta tops out at 1260 Wh, which, in layman’s terms, means that the Bluetti power station will power your electronics for much longer.
I tested these figures in the most simple way I could think of… with a 10-watt light. My Delta managed to keep a little desk lamp on for just shy of 36 hours, while my AC200P fought off the darkness for almost 50.
Verdict
The AC200P has by far the most muscle of the two units.
Battery Cycle Life
As I’ve only had these units for a relatively short period, I don’t have any first-hand experience with overall battery service life, but if the specs are to be believed, then Bluetti AC200P completely annihilates the Delta in terms of longevity.
According to EcoFlow, the Delta will serve you for just over 800 cycles to 80% charge, but Bluetti claims that the AC200P will survive 3600+ cycles to 80%, which means the Bluetti will last more than four times longer than the EcoFlow — nuts, right?
Verdict
The AC200P will outlive us all!
Charging Methods
Both of these solar generators offer multiple charging methods, so no matter where you are or what you’re doing, you can get them topped up and ready for action, but which offers the most flexibility?
| Charging Method | Bluetti AC200P | Ecoflow Delta |
| AC |  |

| Solar | |

| Car | |

| Generator | |
 |

|
| Dual AC | |

| Hybrid Charging | |
|
As you can see, the AC200P gives you way more options (5 overall) when the time comes for a top-up, but this round isn’t won just yet, as we also need to consider charging times.
During my tests, I found that a 700-watt solar array took the AC200P from nearly flat to 100% in just under 3.5 hours, and my AC outlet (120V) took just over 4 hours.
The Delta took roughly 4 hours to reach full charge using my solar array, but only around 90 minutes when plugged into a wall outlet, which is insanely quick.
Verdict
It’s an absolute nail-biter of a round, but I think the AC200P comes out on top… just!
Compatibility
The wattage of a generator may determine power potential, but if it doesn’t have a wide array of output ports, it’s all for naught, so let’s see what these units are really capable of!

Verdict
The absence of a true UPS mode is disappointing, but I find the Delta’s to be lackluster anyway, so it’s another win for Bluetti!
Bluetti AC200P vs EcoFlow Delta: The Final Verdict
With 5 wins to 1, the Bluetti AC200P takes the title here today, but credit where credit’s due, the Delta has some awesome appointments, namely, the wealth of USB-A ports and the lightning-fast charge times.
It’s also incredibly powerful for its size and weight, but it simply doesn’t compare to the might of the ACP200.
