Premium portable power, without the premium price - 1kWh of dependable backup, ready in 45 minutes.

X-Stream: Ready in Just 45 Mins

DELTA 3 Classic (1024Wh) charges from 0–80% in just 45 minutes and fully charges in 60 minutes with AC charging. It keeps you powered faster, smarter, and with greater peace of mind—whether indoors, outdoors, or on the move. X-Stream enables ultra-fast charging without compromising battery life. It intelligently adjusts voltage and power to ensure safe, high-speed recharging. With X-Stream, you’re ready in just 45 minutes.[2]

Recharge fast, three ways.

From flat to ready before you've finished packing.

AC Charging
Plug into any wall socket and DELTA 3 Classic hits 80% in just 45 minutes, or a full charge in 60. Whether it's a sudden power cut or a last-minute trip away, you're powered up before the bags are.
Activate EcoFlow's exclusive Storm Guard Mode[3] to auto-start charging when extreme weather alerts hit—so you're always prepared, even when away.

Solar Charging
Pair it with EcoFlow solar panels for up to 500W of free, silent energy - a full charge in around 2.5 hours of good sun. Made for off-grid weekends at the bach or campsite.

Alternator Charging
On the road, add an EcoFlow 500W Alternator Charger[4] to top up from your vehicle as you drive - 0-100% in about 2.5 hours. Power that keeps up with the journey.

Run the things that matter.

1800W output (3600W surge), with EcoFlow X-Boost up to 2400W.

EcoFlow DELTA 3 Classic (1024Wh) delivers a steady 1800W pure sine wave output with grid-level stability—enough to handle high-demand appliances like microwaves and power tools [5]. With X-Boost™ mode, it supports devices up to 2400W without tripping or slowing down—giving you seamless power for the moments that matter.

Less than 10ms backup, automatically.

When the grid drops, DELTA 3 Classic switches to battery in under 10 milliseconds - fast enough to keep desktops, modems and other sensitive gear running without a flicker. Set it up as an everyday UPS and you may never notice the next outage.

Quiet enough to forget it's on.

At 30dB or less, the Classic runs barely above a whisper. Inside a tent, a caravan or beside your desk, it won't disrupt sleep or focus.

Sometimes Good, Sometimes Not So Good...
Size: X-Large, Color: Aqua
I've bought several of these shirts in the past, and I've always been very happy with them, right up until my latest purchase. Apparently, depending on which color/style you choose, the shirts may be manufactured in a completely different country. And despite Amazon's efforts to make sure their clothing brands have consistent sizing across the board, it's now clear to me that some of those countries are not on the same page. Case in point: Guatemala. My latest Amazon Essentials polo shirt purchases consisted of the colors 'light yellow' and 'rust'. Now, the light yellow shirt seems fine. Maybe a tiny bit smaller than my previous shirt purchases, but nothing major. (I think it says made in Chihuahua - but it's hard to tell.) However, the rust colored shirt is drastically smaller than all my similar-sized Amazon polo shirts. I bought it in size Large, but the shirt tail alone is nearly four inches shorter than my previously purchased Amazon Essentials polo shirts. And while the Large-sized Amazon polo shirts normally fit me quite comfortably, with a little bit of room to spare, this rust-colored shirt is skin-tight. If I didn't know any better, I'd swear it was a size Medium masquerading as Large. All of my previous shirt purchases (I now realize) are labeled as being made in either Madagascar or Vietnam. Those are great. They fit wonderfully. But this new rust-colored shirt (once again, same brand - Amazon Essentials) is labeled as made in Guatemala. And let me tell you, the factory in Guatemala is not on the same page as the factory in Madagascar. Not even close. So yeah, these are great shirts. So long as you happen to buy the colors/styles that are being made in Madagascar or Vietnam. But buyer beware if you happen to get one from the factory in Guatemala, because those guys are using a whole different set of rulers over there. And unfortunately, there's no way to tell until it arrives on your doorstep. I'm normally a big fan of Amazon brand products. But this experience has made me quite a bit more wary about buying their clothing items in the future. It really is so very important that their brands have consistent sizing across all colors and styles. P.S. I actually bought the rust-colored shirt TWICE, because I at first assumed I must have gotten a mislabeled product. But, nope. Both rust-colored shirts are the same, drastically-smaller size, and both are labeled made in Guatemala.

Nice, well fitting and inexpensive Polo.
Size: Large, Color: Red
Don't be deceived by the low price. This is a nice shirt. To me the shirts are a bit "oversized" which I found to be perfect. The large is a "roomy" size large which is what I like. I previously ordered an XL which is my normal size in polo shirts and it was too big, and hung way low. Easy return of the XL and fast shipping of the L was appreciated. Going on a cruise, so ordering a few collared shirts. This is a keeper.

Nice shirt for low price AND 100% cotton! Prepare for shrinkage with warm water wash and medium heat dryer. Use cold water and hang dry to keep length
