There’s been a lot of buzz lately about semi-solid state batteries making their way into power stations. While the inclusion of these batteries sounds impressive, do they actually make a noticeable impact on a power station’s performance? We’re not so sure.
Still, we wanted to find out for ourselves. So, we decided to review the DABBSSON DSB2100 Pro, a relatively new power station that boasts a built-in “EV-grade” semi-solid state battery.
At The Solar Lab, our main goal is to cut through the hype and figure out what’s truly worth your time and money. So, getting our hands on this DABBSSON unit seemed like a great opportunity to test out a new power station brand and determine whether these semi-solid state batteries make a significant difference in terms of real-world performance.
Let’s see if the DABBSSON is the real deal or if you’re better off sticking with more well-known brands like EcoFlow and Anker.
Before we get into the nitty-gritty, let’s address the elephant in the room: who exactly is DABBSSON?
Basically, they’re a fairly new brand that specializes in power stations. While DABBSSON might not be a household name, they already carry four different power stations at varying price points.
While new brands hit the scene all the time, so this isn’t anything out of the ordinary, DABBSSON has made a bit of a splash by advertising their DSB2100 Pro with an EV-grade semi-solid state battery.
According to DABBSSON, this type of battery is more efficient, compact, and performs better than the industry-standard LiFePO4 (lithium iron phosphate) batteries.
Sounds fancy, right? We’re not so sure it’s going to make a big difference. Still, let’s break down the specs and see if this power station can compete with what’s on offer from the big players.

Here’s a quick rundown of what the DABBSSON DSB2100 Pro offers:
The DABBSSON DSB2100 Pro has an MSRP of $1,799; however, it seems to be regularly discounted to $1,199 on their own website. We’ve even seen it for as low as $999 through some third-party retailers, which is a steal if it actually delivers the specifications it’s advertised with.
The design of the DABBSSON DSB2100 Pro is pretty decent—it’s fairly compact, relatively lightweight, and feels well-made.
In fact, it feels strikingly similar to what you get with some of the mid-sized EcoFlow power stations, like the DELTA Max 2 or DELTA 3. From the placement and design of ports to the shape of the expansion battery connector, it’s almost like DABBSSON took direct inspiration from EcoFlow’s lineup. We’d have to confirm it, but it wouldn’t be surprising if an EcoFlow expansion battery cable fits the DABBSSON’s expansion port—they’re that similar.
As for the display screen, it’s functional, but not particularly impressive. It shows the essentials but lacks the modern, feature-filled interface you get with some of the higher-end brands. The app continues this theme – it works, but it’s not as polished as the apps offered by brands like EcoFlow or Anker.
Now that we’ve covered the specs and provided our thoughts on the design, let’s see how this puppy and its semi-solid state battery actually perform.
The DABBSSON’s semi-solid state battery promises higher energy density than a standard LiFePO4 battery, meaning it should be able to store more power inside of a more compact and efficient design. However, in practice, the unit is bulkier and heavier than models with comparable storage capacities, like the above-mentioned EcoFlow DELTA 2 Max. So much for “smaller and lighter.”
When we actually tested its efficiency, we decided we’d fully charge the battery and then see how long we could run a continuous 2,150W load. Theoretically, a 2,150Wh battery should be able to run this load for one full hour if it’s 100% efficient. We knew it wouldn’t hit 100% efficiency, because, frankly, that’s almost impossible, but we still had high hopes given how much DABBSSON leans into the quality of the battery in their marketing.
It turned out that the DABBSSON delivered an 82% efficiency rating, which is respectable, but not ground-breaking.
With that said, even hitting that 82% efficiency wasn’t straightforward, as the unit overheated during the first test. Basically, it shut down once the battery got down to 30% capacity. Keep in mind that this test was run in a garage that was a mild 20°C (68°F), so the shutdown couldn’t have been related to external temperatures causing it to overheat.
Still, we wanted to reduce any potential variables, so we repeated the test at a starting temperature of 18°C (64°F), and while it made it through the full battery discharge, the display screen was flashing red by the end, indicating it was close to overheating.
Overheating is a major concern, especially if you’re planning to use this power station in warmer weather, or you’re just relying on it for all of your power needs in an off-grid situation, like a blackout or remote camping trip. Not a good start, DABBSSON.
When we tested it, the DABBSSON charged with AC power fairly quickly up to the 80% mark, reaching a 0% to 80% charge in about 1 hour and 15 minutes. However, the last 20% takes significantly longer, bringing the total charge time of nearly 2 hours. Again, not great.
We experienced the same thing when we tested the solar input, meaning it charges the first 80% of the storage capacity as it should, then it slows down to a crawl.
The DABBSSON’s 2,400W inverter is somewhat capable, but it really struggles with surges. While they advertise it as having a 4,800W surge rating, it didn’t deliver at all when we pushed it beyond that 2,400W output rating.
Basically, if you plug in a device that briefly exceeds 2,400 watts (like a vacuum when it’s starting up), the DABBSSON responds by reducing the voltage rather than just temporarily handling the surge, like advertised.
This voltage drop can be harmful to sensitive electronics, like laptops, medical devices, camera batteries, and even smartphones, making this power station a poor choice for running certain pieces of equipment. Once again, we were not impressed.
While the DABBSSON isn’t the loudest power station we’ve tested, its fans are noticeable when it’s running any sort of heavy load.
Sure, it’s quieter than some of the bigger EcoFlow models, like the original DELTA Pro, but much louder than pretty much anything on offer from Anker. For camping or RV use, the noise level is tolerable but not ideal.
What really puzzled us is the fact that overheating is such a major issue with this unit, but it’s still fairly loud. When you’re dealing with a unit that overheats, you’d assume that would be because the internal cooling fans don’t run properly. Somehow, the fans run continuously and create a lot of noise, but they don’t seem to do much. Basically, you’re getting the worst of both worlds.
Normally, this would be the part of the article where we’d dive into a fairly balanced list of pros and cons; however, it’s not really worth it with this particular power station. As you may have guessed by now, there are just way too many things we don’t like about it.
Sure, if you can pick one up at that discounted price of just $999, it’s a decent deal, but, then again, it should be inexpensive given how many problems we encountered during our testing. Here are just a few of the issues that really stood out:
Right at the top of our list of complaints is the brutal overheating issue. When you buy a power station, it should be able to easily sustain the output power its inverter is rated to. With this unit, it can only do so for a short period of time, then it overheats. That just isn’t good enough. If you bought a car that could supposedly hit 150 mph, but it topped out at 65 mph, you’d be pissed off.
The voltage drops during surges are also concerning, especially if you’re like us and you like to use your power stations to power sensitive electronics, like laptops and camera gear. Then there was the relatively slow battery charging through both the AC and solar inputs.
On top of all of that, it had a weird issue when we tried to run a pass-through charging test. Basically, when we tried charging the internal battery while also using the power station to run a computer, it shut the computer off before it allowed it to pull power. This is the first time we have ever seen a power station do this—it’s both weird and really inconvenient.
Finally, even DABBSSON’s website left us with a bad impression. It’s full of empty promises and borderline sketchy claims—basically, they exaggerate what their power stations are capable of.
We even tried calling their support line to ask a few questions, but that led us absolutely nowhere. After a few rings, the line automatically plays a recorded message that says: “The customer you are calling is unavailable at the moment, please try again later.”
We also sent an email to the address listed on their website. The email, sent at 4:25 p.m., read: “Hey, I'm looking to speak with someone about a question I have regarding ordering a power station. What's your phone number? The one on the website that we called didn’t work.”
They responded at 11:22 p.m., almost seven hours later, which is just insane and tells you what kind of customer support you can expect if you buy something from them. Keep in mind, we’re talking about a product that can cost well over $1,000, and their delayed response was basically: “Hey, we don’t have a phone number you can call—you’re on your own.” That’s just inexcusable.
Look, there’s no denying that this product has a few things going for it, but with its issues and the complete lack of support, it’s simply too much of a risk for us to feel comfortable recommending it to our readers and viewers.
The DABBSSON DSB2100 Pro has some appealing features, like the built-in light, solid array of ports, and a reasonably sized and expandable battery. If you can pick it up for under $1,000, you’re getting a decent entry-level power station for a budget-friendly price.
However, it falls short in some really important areas. We just encountered way too many issues, like the poor surge handling and overheating problem, which we’d have to say verge on deal-breakers for us. Plus, the semi-solid state battery didn’t offer any noticeable advantages over a standard LiFePO4 battery, which was the main selling point for this thing.
If you’re on a tight budget and need a power station for light use, the DABBSSON might be worth considering. But for reliable performance and better overall value, we’d still recommend power stations from more trustworthy brands like EcoFlow or Anker.
Both the EcoFlow DELTA 2 Max and the Anker F2600 offer similar battery capacities, far fewer issues, and more polished designs. Plus, they don’t actually cost that much more than the DSB2100 Pro.
So, is the DABBSSON and its semi-solid state battery worth it? Probably not.
