The advertised deal cannot be verified from the available official Baseus pages. Baseus says its 2026 Prime Day promotion ran from June 11 through July 15, so it had ended by October 7, 2026. Its official pages show a $29.99 Airpow power bank rated at 20W and a separate 20,000mAh Blade rated at 100W—not a 140W model matching the claim.
Did Baseus offer a 20,000mAh 140W power bank for $29.99?
The official Baseus sources available do not confirm that combination of capacity, output, price, and Prime Day availability. The exact product model and retailer listing remain unidentified. Without the original retailer listing, the $29.99 price and 140W specification should not be treated as a verified offer.

Baseus’s 2026 promotion page gives the sale dates as June 11 through July 15, 2026. Those dates are past as of October 7, 2026, so the promotion is not a current “last chance” offer.

What the official Baseus listings actually show
The two relevant Baseus listings describe different power banks. Neither establishes the 140W deal in the headline.

| Model | Capacity | Maximum output | Price and availability shown |
|---|---|---|---|
| Airpow | 20,000mAh | 20W | $29.99; marked sold out on Baseus’s page when accessed October 7, 2026 |
| Blade laptop power bank | 20,000mAh | 100W | Baseus’s catalog displayed pricing; current availability and any deal need to be rechecked |
Baseus’s Airpow product page supports the 20,000mAh, 20W, and $29.99 details, but it does not describe a 140W charger. The separate Blade listing identifies a 20,000mAh, 100W model. Its specifications should not be attributed to the Airpow—or to an unidentified product in the deal claim.
What to check before buying
If you find a retailer listing for the advertised deal, verify the exact model before relying on its price or specifications. Compare the details on the listing with the manufacturer’s page, and confirm that the seller still has the item in stock.

- Model: Check the model name or number, not just “Baseus” and “20,000mAh.”
- Maximum output: Confirm the stated wattage for the specific model. The official listings above show 20W for Airpow and 100W for Blade.
- Ports: Check the port configuration and whether the listing’s output claims apply to one port or shared output; the cited pages do not establish port details for the alleged 140W item.
- Price and availability: Verify the live retailer price, seller, and stock status. Baseus’s Airpow page being listed at $29.99 does not establish an Amazon or other retailer offer for a different product.
Until a retailer listing identifies the model and substantiates the specifications, treat the “20,000mAh 140W for $29.99” claim as unverified rather than substituting either of these Baseus products.
