Portable Power Station DELTA 3 Plus, 1024Wh LiFePO4 (LFP) Battery, 1800W AC/140W USB-C Output, Solar Generator (Solar Panel Optional) for Home Backup, Camping&RV

The EcoFlow Delta 3 Plus is, without exaggeration, one of those rare devices you wish you could rate six stars just to properly communicate how absurdly good it is. Most portable power stations feel like compromises—good at some things, mediocre at others, never quite earning total trust. The Delta 3 Plus is the opposite: it behaves like a fully grown UPS, a renewable energy appliance, and a field-grade generator all sharing the same chassis. And thanks to its 10ms switchover, it keeps networking racks online so smoothly you’ll have to check the logs to confirm the power even flickered. For small business racks, lab gear, or home network cores, it simply doesn’t flinch. That would already be enough to recommend it, but then EcoFlow wandered into “hold my beer” territory and added dual MPPT inputs that accept up to 1000W of solar. Actual, full-size house panels plug into this thing like it’s a pint-sized powerwall, and the result is borderline magical. You can run a firewall, switch, modem, controller, and accessories for 8+ hours straight… and then watch the Delta 3 Plus refill itself on solar faster than many UPS units recharge from AC. For anyone trying to build a cost-efficient hybrid UPS solution—or just wanting peace of mind without buying enterprise battery cabinets—this is the most practical and overachieving option available. The versatility is what seals its legendary status. In the rack, it’s a clean, quiet, LFP-based protector that outperforms most UPS units on stability and lifespan. On the job site, it runs tools, testers, laptops, APs, or anything you’d normally plug into a generator—minus the noise, fumes, or neighbors glaring at you. And once work is over, it becomes the ultimate camping battery, perfectly happy to run lights, induction cookers, or even a full-size microwave because yes, someone will try it. Fast charging makes it almost unfair, thermal control is dialed-in, and the whole device feels like it was engineered by people who decided portable power should be fun, not stressful. What makes the Delta 3 Plus such a “must own” device is how it quietly replaces multiple categories of equipment. It’s a UPS that lasts longer. A solar generator that charges faster. A portable battery that behaves like a home backup unit. A field tool that simply refuses to fail when everything else is having a bad day. It’s the one power solution that makes you immediately wonder how you ever worked—or camped—without it. If there’s a higher tier than “highly recommended,” this belongs in it. ⸻ Pros • 10ms switchover rivaling high-end UPS units • Two MPPT solar inputs supporting 1000W—works with house panels • LFP battery = safe, long-lived, cool-running chemistry • Powers a full SMB rack for 8+ hours with ease • Fast charging, quiet operation, incredibly stable inverter • Equally brilliant for racks, field work, camping, and off-grid setups • Feels like multiple devices replaced by one overachiever Cons • Heavy—portable power still means “you’re carrying power” • Overkill for anything smaller than a full rack or campsite • EcoFlow’s app occasionally wants to be the star of the show • You will absolutely end up wanting two

Here's my honest review! The EF ECOFLOW DELTA 3 Plus with 400W Solar Panel is hands down one of the most impressive solar generators I’ve used. Whether you're prepping for emergencies or need portable power for camping or RV life, this system delivers. The 1000W solar input is a game-changer — paired with the included 400W panel, it charges surprisingly fast even in partial sunlight. I love that it uses an LFP (LiFePO4) battery, which means long-term durability, more charge cycles, and greater safety compared to traditional lithium-ion. The build quality is outstanding — solid, compact for the power it holds, and easy to move around with the built-in handles. The output options are versatile, with plenty of AC outlets, USB ports, and a car socket, making it easy to power everything from a CPAP machine to a fridge or laptop. Pros: *Fast solar charging with 1000W input (400W panel included) *Durable and safe LFP battery (long cycle life) *Great for home backup, outdoor use, or travel *Quiet operation and intuitive display * Wide range of output ports for multiple devices * Solid construction, reliable performance Cons: ➖ A bit heavy, but expected for this capacity ➖ Pricey — but you get top-tier features and battery life

I wish I had not waited so long. I originally purchased this unit for off-grid amateur radio operations. It works very well for that purpose. But recent storm related outages allowed this unit to really demonstrate its capabilities. The unit paid for itself when it kept my fridge and freezer running during a recent outage. This unit is reasonably light, very portable, can handle a variety of tasks (charging cell phones, computers, running coffee makers, fridges, and freezers, and even driving my tankless water heater. The first day I recharged it using my gasoline generator. It recharged quickly. The next day I was able to deploy the solar panels (the panels can recharge the system in a couple of hours in very good conditions). At one point, the panels were actually recharging the unit while powering a fridge. Impressive. I love that charge-through capability. I wish the cables for the solar panel connections were longer. And I wish an anchoring system for the solar panels was provided (the light panels are great, but are very unstable in windy conditions). While I still have and use gasoline generators, this is my go-to generator for all kinds of projects. I'm pleased I purchased it and am planning to buy another one this year.
