EcoFlow portable power station Delta 2 Max deal: $999 at Amazon

GET A FREE ITEM: As of Sept. 12, when you purchase $800 worth of qualifying EcoFlow items at Amazon, like the Delta 2 Max solar generator on sale for $999 (reg. $1,699), you'll get a free benefit item.

Getting a hefty discount on a big purchase is always a win, but scoring a free gift on top of it feels like hitting the jackpot. For a limited time, Amazon is running a promotion on select EcoFlow products that does just that. If you're in the market for a serious power station, you can snag one on sale and get a second piece of gear for free.

As of Sept. 12, the promotion applies when you spend $800 or more on qualifying items. One example is the EF EcoFlow Delta 2 Max solar generator, which is currently on sale for $999, a $700 discount off its $1,699 list price. Since that purchase is over the $800 threshold, you qualify for the free "benefit item."

To get the deal, you first need to use the "Qualifying item(s)" filter on the promo page to add at least $800 worth of products (like the Delta 2 Max) to your cart. Next, click the "Benefit item(s)" filter to view and add your free gift to the cart. The discount should be applied automatically at checkout, making the benefit item free.

The Delta 2 Max offers 2048Wh of storage and a 2400W output, which is enough to run a mini fridge for over 29 hours or power 15 devices at once. It’s ideal for home backup during an outage or for powering a campsite. One of its best features is the lightning-fast charging, reaching 80 percent in just 43 minutes when using both a wall outlet and solar panels.
