Tom’s Guide reported that the Ninja FrostVault 50-quart cooler kept ice frozen for five days in its writer’s test. That is an editorial test result, not a five-day guarantee from Ninja: the manufacturer describes ice retention as lasting “for days.” Tom’s Guide also reported an Amazon price of $199 on October 5, 2026, but that dated offer is not confirmed as still available on October 7.
What supports the five-day ice claim?
Tom’s Guide’s October 5, 2026 article says its writer tested the Ninja FrostVault and found the ice completely frozen after five days. It also reports that soda cans remained completely cold after eight days. These are results from the publication’s account of its test; the available information does not establish a controlled laboratory protocol or independent replication.

Ninja’s official product page makes a less specific claim: ice retention “for days.” It does not promise five days or cite the test result. Treat five days as a reported outcome, not a guaranteed duration; real-world performance can depend on conditions such as how the cooler is packed and used. Ninja’s product listing identifies the model as FB151WH.
Is the Amazon Big Deal Days price still available?
Tom’s Guide reported a price of $199 on Amazon, reduced from $249, on October 5, 2026, and described it as 20% off. This is a dated price snapshot, not confirmation of the live listing on October 7. The current price, stock, deal end date, Prime eligibility, shipping terms, and exact listing variant are not established here. Check the current Amazon listing before buying and confirm it is model FB151WH.

What makes the FrostVault different?
The cooler’s defining feature is a separate Dry Zone drawer. Ninja says its FrostVault technology transfers cold into the drawer to keep food “cool, dry and separate at food-safe temperatures (under 40° F) for days.” That design may be useful when you want food kept apart from loose ice and drinks; it is distinct from the broader ice-retention claim for the main cooler.
Capacity, dimensions, and warranty
Ninja’s product listing gives these specifications for the 50-quart model:

For vehicle fit and carrying, check the listed dimensions and weight against your storage space and how you plan to move the cooler. The can counts are stated separately for use without ice and with ice, so do not treat the larger figure as the usable count when the cooler is packed with ice.
What to check before you buy
- Confirm the current price and stock, and verify the listing is for the 50-quart FB151WH rather than another size or variant.
- Decide whether the separate Dry Zone drawer is useful for your food-storage needs.
- Check the cooler’s dimensions and 29.01-pound weight against your vehicle and transport needs.
- Read the warranty terms and retailer listing for the exact item being sold.
- Ninja’s page shows FrostVault ice packs and a divider insert/cutting board among the accessories. Check current availability and compatibility with the specific listing before purchasing either.
The cited sources do not provide comparable test results for rival coolers, so they do not establish that the FrostVault outperforms other models overall.
