DJI's Power 2000 portable power station is $749.99, down from $1,299, one of several early Black Friday markdowns on backup batteries as of October 21.
That $549.01 cut works out to about 42%. Anker's Solix C2000 Gen 2 is close behind at $899.98, down from $1,499 (a $599.02, or roughly 40%, reduction). EcoFlow's DELTA 3 Max is $899, down from $1,199, about 25% off. The Bluetti Apex 300 is $1,699, $300 off, or about 15%.
Jackery's discounts are shallower. The Explorer 300 is $259 (from $289), the Explorer 2000 V2 is $899 (from $999), the HomePower 3000 is $1,349 (from $1,499) and the HomePower 3600 Plus is $1,709 (from $1,899). Each is about 10% off. The HomePower 3000 bundled with solar panels, at $1,799 from $2,149, gets about 16%. EcoFlow's Trail 300 DC with a waterproof travel bag is $169, $30 off.
The Jackery Explorer 1000 v2, the roundup's overall pick, shows why the baseline matters. It is $499 at Amazon, $60 below Amazon's $559 price. Amazon's price is itself $30 under the $589 list price on Jackery's website, so the saving against that figure is $90. It is also not a record: the roundup's authors said it fell to $448.98 in June, which is $50.02 lower. The unit weighs 23.8 pounds, holds 1,070Wh and puts out 1,500W.
The roundup's authors said they check price history and list prices to catch inflated starting points. By that test, the Jackery is the only deal listed with a documented baseline, and it is a mild one. The 40% cuts from DJI and Anker are the biggest numbers here, but the source gives no price history for either. Treat them as promising, not proven.
