$7 Each

Each charger in the set offers a total output of up to 40W and features two USB-C charging ports and two USB-A charging ports per module. This 4-in-1 design lets you charge four devices at once from one wall outlet without having to deal with multiple adapters or occupying multiple outlets. The USB-C ports are Power Delivery-enabled and offer up to 20W each which is enough to charge an iPhone 16 from 0% to 50% in just 30 minutes (three times faster than a standard 5W charger). The USB-A ports offer a maximum of 3.1A at 5V which is perfect for charging older gear, headphones or tablets.

Safety features are at the top of the list with these chargers: There is a smart chip in every block that protects your devices against overcurrent, overvoltage, overheating, and short circuits. The outer casing is made of ABS + PC fireproof material and gives an extra layer of protection and ruggedness. It lets you charge your devices overnight or leave them unattended without having to worry about harm.

Two white charger blocks are shipped with each package and each is protected by a 24-month warranty. In case you face any issue, the company assures to resolve your issues within 24 hours.

At just $13 for two, it’s the kind of deal that’s hard to pass up.
