Walmart Inc. is rolling out three Android-powered tablet computers this week, all priced under $100.

The devices, under Walmart’s Onn store brand, include an 8-inch version for $64, a 10.1-inch model for $79 and one at the same larger size with a detachable keyboard for $99, the retailer said. All have Google’s Android operating system, 16GB of storage and promise 5.5 hours of use before a charge is needed.

The new gadgets are part of Walmart’s broader push to revitalize its electronics section. The company has also started selling Bluetooth-enabled wireless earbuds for $39.88 that are designed to undercut the more expensive Apple AirPods.
