Two-port USB charger pair

The BSTOEM ZYH-J45 pack contains two compact wall adapters, each with dual USB Type-A ports rated at 5 V and 2.1 A. They accept AC input from 100 V to 240 V, making them suitable for worldwide travel or home use. Built-in safeguards stop charging automatically when a device reaches full capacity, protecting against over-current, over-voltage and overheating. The palm-sized cubes are lightweight and easy to store in a bag or drawer.

Broad device compatibility

These chargers work with any gadget that draws power through a standard USB-A cable, including recent iPhone, iPad, Samsung Galaxy, LG and Kindle Fire models listed by the supplier. They are not intended for devices that require USB-C Power Delivery, Quick Charge or higher wattage than 10.2 W per port. Buyers needing faster charging speeds or a USB-C connector should consider other options.

10.2 W per port output

Each USB-A port delivers a maximum of 5 V at 2.1 A, giving 10.2 W of power. This single figure determines whether the adapter can charge your specific device at its optimal rate. Check your device’s required input before purchase.

Questions about this item

How can I confirm the BSTOEM ZYH-J45 is delivering the rated 5 V 2.1 A output after I plug it in?

The charger has built-in overcharge, overcurrent and overheating protection and stops automatically when the device is full, so normal charging without excessive heat indicates it is working as intended.

What comes in the box and do I need to buy any cables separately?

The package contains two white dual-port USB wall adapters; charging cables for your devices are not included and must be purchased separately.

Which version should I choose if I need a total of 10.2 W per adapter for fast charging?

The listed 10.2 W dual-port model provides 5 V at 2.1 A per adapter and is the only version described in the specifications.
