Anker and Jackery have introduced big discounts across their most popular portable power stations, preparing for Prime Big Deal Days next week. We're tracking Anker's best deals at its own website and on Amazon, while Jackery's discounts can be found on the retailer's website.

Anker's SOLIX brand is hosting an early Prime Day sale with early bird deals, free gifts, and more. This sale is focused on Anker's high-end SOLIX portable power stations, with options that range from 1-2 days of backup to 3-5 days of backup. For cheaper options, Amazon has notable markdowns on lower-cost SOLIX batteries, like the popular SOLIX C300 Portable Power Station with Lantern for $199.99 ($50 off). If you're shopping on Anker's website, be sure to make your purchases before October 5, when the sale ends.

Over on Jackery's website, you'll find up to 65% off a wide array of portable power stations, solar generators, add-on batteries, and more. This is another Prime Big Deal Days early access event, and is set to run through October 3.

Deals include the SOLIX C200 at $129.98, SOLIX C1000 Gen 2 at $499.99, SOLIX F3000 at $1,399.99, and Jackery Explorer 300D at $209. Note: MacRumors is an affiliate partner with Jackery and Anker.
