Anker and Jackery are both running early Prime Day sales on power stations, and the numbers don't quite back up their own headlines.
Anker's SOLIX sale, advertised at up to 40% off, runs on Anker's site and Amazon through October 5. Jackery's separate early access event, advertised at up to 65% off, runs through October 3. Run the actual math and the SOLIX S2000 drops from $1,199 to $679.99, a 43% cut that beats Anker's own advertised ceiling. Jackery's steepest real discount is the Battery Pack 2000 Plus, down from $1,399 to $799, also a 43% cut. That's nowhere close to the 65% the headline promises.
That gap is the point. Up to percentages usually come from a single outlier SKU, while most of the catalog sits well below it. Roughly half of Anker's lineup is discounted 15 to 25%, and most of Jackery's items are discounted 10 to 16%. Line the two sales up side by side and the real best deal from both brands lands at almost the same 43%, no matter what the marketing copy claims.
Before Prime Big Deal Days officially opens next week, skip the percentage banner. Check the per item price against the original. That's the only math worth trusting.
