Evolution™ F Series 1200W, 120V Pure Sine Wave Inverter/Charger with 12V Input & 40 Amp Charger
Pure sine wave inverter/charger with 6 programmable charging profiles – 2, 3 and 4 stages with Equalization. For use with Lead Acid or Lithium Batteries. Samlex Evolution™ Series inverter/chargers provide reliable AC power wherever it’s needed. For use with boats, RVs, cabins and specialty vehicles, as well as alternative energy, back-up and emergency power applications.
Adaptive Battery Charger Option for Lead Acid Batteries
- 6 programmable charging profiles – 2, 3 and 4 stages with Equalization
- Algorithm monitoring in the Bulk Stage assesses the battery’s condition. The remaining charging stages are based on the battery’s condition rather than a pre-set charging time.
- Reduces excess charging time and extends life of battery
Transfer Switch
- Zero transfer time when switching from Inverter to AC input source. When AC input source comes on, the inverter synchronizes with the incoming wave form and then transfers instantly at zero crossing without interruption to the load.
Surge Capacity (Active Power Boost)
- The inverter has a surge capability of 3X its continuous power rating, allowing it to turn on loads with high starting surge.
- Inverter loads can exceed the continuous power output by the Power Boost Allowances without triggering and overload fault.
- There is no need to upsize to a larger inverter/charger to handle a heavy surge load, resulting in reduced costs.
Solar Input
- Connect a solar charge controller (up to 50A) directly to the EVOTM though the Battery Charger External DC Input
- External charging current is monitored to free up more power from the grid to be available to the load while charging.
- ONLINE Mode can be used to prioritize Batteries/Inverter over the grid, ideal for those who want to operate primarily on solar power, even when the grid is available (when grid is costly).
State-of-the-Art Technology
- Multiple physical points of protection monitoring are scanned up to 10,000 times per second to detect adverse internal and external conditions.
- The EVO™ is practically indestructible. The EVO™ will detect fault conditions and initiate a healthy shutdown before any damage can be done.
AC Input / Output Option
- AC Power Cord Inlet and Duplex GFCI outlet: EVO-1212F/1224F; hardwired: EVO-1212F-HW/1224F-HW
- The EVO-RC-PLUS remote control (sold separately) can be used to capture detailed EVOTM performance data, stored on a removable 16GB SD Card. Advanced features for programming various parameters and modes of operation. 4 rows of 20 character alpha numeric LCD display for messaging.
- The EVO™ uses five temperature sensors placed throughout the unit to determine operation of 2 speed controlled cooling fans. Reduces unnecessary fan noise and energy consumption by only running when and where the fans are needed.
Applications:
- Boats, RVs, trucks, specialty vehicles
- Alternative energy, off-grid, cabins, remote locations, areas with unreliable utility power
- Back-up and emergency power applications
- ABYC Compliant

Great Queen Size Air Mattress - NO Fuss
Style: 18", Color: Grey, Size: Queen
Great air mattress! Comfortable to sleep on. Powerful pump. Nice size. The bag to store it is very convenient and one of the easiest to put bed in once deflated. Reviews spot on with this product.

Skeptical at first, but after first use (so far) it’s a solid product
Style: 22", Color: Grey, Size: Queen
I initially bought this to stay at my MIL’s senior community (to help her get settled), so I didn’t want to spend a lot of money on it and I planned to leave it for other relatives that might want to visit. I expected it to be cheap-ish quality and probably not last through my two week stay.
First off, set up was a breeze. I laid it out and started inflation and it took about 4-5 minutes to fully inflate. The motor made noise, but it’s to be expected from something like this—I can say that it wasn’t as noisy as our Costco-bought mattress.
Second, it’s big—but that’s not a bad thing as much as I thought anyway after I saw it fully inflated. Turns out, for me, it’s a good thing. Our Costco mattress sits low to the floor and as it deflates a bit during the night, it’s tough to get up. This one (the 22” model and the largest one at this writing) is wonderful as I can sit on the edge of it and stand up easily. Your experience may be different, but for older folks it makes it really easy to get out of bed in the morning.
How does it sleep? Well, since I was visiting by myself and my significant other wasn’t with me, I can only speak for a single sleeper. It was really comfortable! It did take a bit of tweaking though as I thought I would like it more firm as I like to side sleep. The first couple of nights were a bit rough as I tossed and turned a bit in my sleep—I found that I couldn’t get comfortable on my side. For the reviews that say that it deflates after sleeping on it, I can say that it did seem to lose some air after the first two nights. The manufacturer does state that it does “stretch” and not deflate. As I wanted to test that statement, I didn’t change the firmness of it by re-inflating it to where I had it. The third and fourth nights were better sleep and I didn’t feel like the mattress deflated at all, so I found the stretch statement to be valid—it wasn’t losing air. After that night, I re-inflated it to where I thought I’d like it. The next night was the same tossing and turning that I had those first two nights, so I concluded that I needed to make it less firm and I actually DEflated it a bit and for the rest of the stay it was perfect! I didn’t have to touch it and I even unplugged it.
When I was getting ready to leave, I started the deflation process by turning the dial in the opposite direction. It took longer to deflate, so I walked away for a bit—I’d guess about 7-8 minutes. When I came back the mattress was flat as a pancake and ready to fold. This is the only hassle of the process as folding it to get it into the storage bag and back into the box (for storage). I do like the tote that they provide as the handles make it easy to lug about.
So, the first use was a success. If repeated uses reveal issues, I’ll report back. I will say that I plan to buy another one to replace our beloved Costco air mattress—she’s showing her age and the height of this one as well as the cost make it a no-brainer to get it as a second. We’ll use this one until it dies (if it even does) and then fall back on our old one if needed. I gave an overall 5 stars for the product with 4 stars for sleep quality and comfort only because your idea of these two might be a bit of a learning experience until you find your inflation sweet spot—so it’s not just an “inflate fully and use” type of scenario.

Comfortable, high-rise air mattress with built-in pump
Style: 22", Color: Grey, Size: Queen
The Intex Dura-Beam 22-inch Queen air mattress is one of the better inflatable beds I've used. The built-in pump is very convenient — no need for an external pump or battery-powered inflator. It inflates to full firmness in a few minutes and deflates just as quickly. The 22-inch height makes it easy to get in and out of, similar to a regular bed height. The plush comfort top adds a softer surface feel. The 600 lb weight capacity is reassuring for heavier users or couples. I've had guests sleep on this for multiple nights and they reported sleeping well. It held air overnight without significant deflation. My only note is to store it carefully to avoid punctures from sharp objects. Overall a great value for guests or camping.

Very good
Style: 18", Color: Grey, Size: Queen
I recently purchased this inflatable mattress from Amazon, and I’m honestly very impressed with the quality and comfort. It inflated quickly and was very easy to set up. The material feels durable and strong, and the mattress stayed fully inflated throughout the entire night without losing a

This is a very good air mattress
Style: 13”, Color: Grey, Size: Twin
I love this mattress so much I work overnights and I needed something to sleep on so I bought this mattress and it was the best mattress ever it’s so comfortable I purchased it Dec 24th2025 and it’s now starting to deflate I can’t find any holes in it but I still use it. I’m not gonna get rid of it because I can still sleep on it I just need to inflate it two times throughout the night it doesn’t bother me because it’s so comfortable. I’m not gonna lie I did purchase another one. But I’m 125 lb but the grands can sleep on it when they stay over so I will be keeping it. This is a really good air mattress well worth your money.
