The EcoFlow Delta Pro 3 takes portable power to new heights. This isn't just a power station that can power your iPhone while camping; this is a power station that offers the ability to operate as a whole-home backup solution, power an RV, power an off-grid domicile, charge a Tesla, or even run an industrial popcorn machine for hours on end (more on this later).

Much like Anker Solix's F3800, I have written two pieces on the EcoFlow Delta Pro 3, the largest offering of the company's line-up. But this new model, the third-generation, boasts more capacity, faster charging, and improved expandability compared to the earlier Delta models, making it one of the most advanced consumer power stations available - and a phenomenal option for those who need high output and high capacity.

EcoFlow Delta Pro 3: Price and Availability

The base price of the Delta Pro 3 is $3,699, currently on sale for $3,199. Since its release, the cost has lowered. However, it is still a premium offering. EcoFlow is offering a handful of bundle options to expand the already impressive capabilities of its flagship power station. These include a solar panel bundle, a dual-fuel brilliant generator bundle, and an extra battery bundle that could expand the capacity to 48kWh.

EcoFlow Delta Pro 3: Unboxing & first impressions

One of the first things I noticed about the Delta Pro 3 was its compact size and incredible weight. I know batteries are heavy and regularly work with large power stations, but I was still shocked. For the power output that the Delta Pro 3 can produce, the size is not that overbearing. It does, however, weigh in at just over 113 pounds, so make sure that you either have help to move it around or that you're not going up and down stairs or loading it anywhere.

The build quality is what I would expect from a company like EcoFlow. It has an industrial-grade IP65-rated battery for dust and water resistance, too.

Another shocking thing about the design is it has a built-in telescoping handle. I expected wheels, mostly because I saw them in the picture before arrival but also because the unit is so heavy. I also noticed a carrying handle on the top, so I expected that to be it. However, once I got the unit, I saw a telescoping handle that comes out of the underside of the power station, allowing for even easier transportation without breaking your back to move the power station from place to place on the large back wheels.

This portable power station has a massive battery, so don't expect to take this thing hiking. However, it is crucial to note that EcoFlow has integrated some rugged wheels to get you to where you may need power the most. Outside the telescoping handle, the EcoFlow Delta Pro 3 has an industrial-grade plastic casing to help it withstand heavy use. And, while I don't think anyone would intentionally take this beast out in the rain, it is IP65-rated, making it resistant to dust and water and, therefore, suitable for indoor and outdoor use.

EcoFlow Delta Pro 3: In use

Portable power stations are something that I didn't realize how much I would use them until I had an abundance. They are so helpful not only as home backups as UPS but also as power in strange places you may not have power or even to offer a port you may not otherwise have.

I've had the EcoFlow Delta Pro 3 for many months and tested it in many scenarios. Some have been realistic and useful for the masses, and others have been highly specialized and unique to what I needed.

First, to discuss the common uses, this power station functions beautifully as a UPS and whole home backup solution. Granted, if you are trying to hook this up to run your entire house with the standard outlets, you'll need some additional pieces to wire it into your home. But, if you want to run a local dose of plugs that can be plugged into this power station, you are also in luck. This unit operates as a UPS with a 10ms switchover time, which ensures no interruptions for critical appliances or lamps, just the same.

What sets this power station apart is that it's powerful enough to output what a large generator would, but without fumes or gas. So, you can get 240v power anywhere without making room for venting a gas/diesel generator. I did this a couple of times for testing purposes to see what the capabilities are.

I was able to push the Delta Pro 3 to charge a Tesla (though, of course, not full capacity off just the internal battery, but it was able to add quite a bit of capacity to the battery while sipping off the 120v wall), I was able to run a giant industrial sized bounce house blower, and even a commercial sized popcorn machine on full power for several hours while also plugged into a 120v outlet.

This power station is phenomenal for off-grid power, running off of just the sun and some solar panels. It can be an excellent option for those trying to make a fully powered tiny home in a van or truck. It can be a fantastic option for high power on demand anywhere. It can also be an excellent option for job sites.

EcoFlow Delta Pro 3: Final verdict

The EcoFlow Delta Pro 3 is a game-changer for high-capacity portable power. With seamless smart home integration, massive battery capacity, and rapid charging options, it’s one of the best solutions for home backup, RV life, and professional off-grid power. Though heavy and pricey, its performance and versatility justify the investment for serious users needing a portable power solution.

The ProtoArc EC100 is an ergonomic office chair designed for all-day comfort without breaking the bank. I've had the opportunity to review the best chairs for years, and many of them are getting expensive. ProtoArc, while I didn't know them very well before this chair, has created a quality chair that is easy to set up, comfortable, and good-looking for the more palatable cost of just under $200.

ProtoArc's focus for the EC100 is lumbar support, breathability, and a great cushion, all in a budget chair far more accessible than some bigger-named companies we've reviewed in our round-up of the best office chairs.

ProtoArc EC100: Price and Availability

The ProtoArc EC100 has excellent build quality for a mere $189 and is sold on Amazon, ProtoArc's website, and a handful of other retailers. ProtoArc runs occasional discounts.

At the time of review, the red and black colorways were sold out, but the grey option is still available (as you'll see in the photos since I have the grey color).

Lastly, the EC100 comes with ProtoArc's fair but not amazing two-year warranty and a 30-day return policy.

ProtoArc EC100: Unboxing & first impressions

The ProtoArc EC100 was an effortless and straightforward assembly. It took around 20 minutes to complete, and the parts were clearly labeled.

Everything was neatly packed in the box, so nothing got damaged in transit, and every piece felt well-built, making me feel confident that this chair wouldn't just break right away.

My first impression of this chair was that it was a good mix between premium and budget. It has a sturdy base, quality parts, and a decent design. It fits the design language of other ergonomic office chairs I have tested. Further, after assembly, none of the pieces bolted together felt loose, which is another good sign of a quality design. The mesh back is lightweight and highly breathable, which I love, and the seat cushion is relatively thick and well-padded.

One of the best things about the ProtoArc EC100 is that I can recommend it as a great option to most people. This is partly because of the budget-friendly price tag and partly because this chair is designed for individuals 5'3" - 6'5" with a weight range of 90lbs to 280lbs. That's a huge range I'm not sure I've seen before.

While in use, the sturdy and high-quality frame is sleek and provides the support needed. The EC100's mesh back is breathable, keeping users cool during the day and helping cut back on getting sweaty while cocooned into an old leather-style chair.

The cushion has a spring enhancement, providing better pressure distribution, according to ProtoArc. I like to see it as feeling like there is support to my support, providing a comfortable seat, but also feeling like I'm not going to sink into memory foam or a soft cushion -- it feels like I have something holding me up as well. ProtoArc also claims that this spring-enhanced seat cushion provides better pressure distribution, making you feel more comfortable for longer. Pairing this with another feature that ProtoArc boldly proclaims is the Ergonomic S-shaped backrest, which is supposed to help with spine alignment. Lastly, add those features to the 7-position armrest, and you get a highly customizable, ergonomically comfortable, built-for-all chair at a great price, too.

ProtoArc EC100: In use

My team and I have had this chair in our rotation since September 2024. Yes, that's been a while. However, this chair has worked its way around and into the perfect desk setup for this kind of chair. Since this chair is highly flexible, I wanted to pair it with an equally flexible desk since it is highly adaptable. So, I paired it with a desk that works as a hot desk right now, easily able to run any computer setup or even frequently running an iPad Air setup.

This chair is frequently used by individuals who are around 5'5" and are under 150lbs and those who are above 6 feet and are just over 200lbs. What's impressive about this chair is that it feels (or so I am told) just as comfortable to both ends of the spectrum. The lumbar support is firm but not too firm, the seat cushion is relaxed, and the armrests are nice and adjustable. However, one thing I have noticed is that the seat cushion is comfortable, but it is less breathable than if you have full-mesh chairs. If you run pretty warm during the day and want something to help keep you cool, this can do it for your back, but it may be too warm for your... lower half of your body...

Another thing we noticed compared to other chairs is that while many can choose where to click into place at a few options while reclining back, this chair can only sit up, lay back, or have tension in between, with no other locking positions. Most of the time, this is fine, and we don't notice, but in the few times one of us has wanted to lock it back, it's a bummer that we only have two options.

ProtoArc EC100: Final verdict

The ProtoArc EC100 is a budget-friendly ergonomic chair designed to fit a wide range of heights and weights while staying comfortable and adjustable. While it's not perfect, it's a fantastic option for those who need a chair for a hot-desk situation, want a chair for their home office, or if you are simply in the market for a chair and don't want to break the bank.
