Dual USB wall charger for US outlets

This 5V 3.4A black charger plugs into any standard US AC 100/240V wall socket and provides two USB ports for tablets, phones and other USB-powered devices. It is designed for travellers and home users who need a single compact adapter for multiple gadgets. The unit is supplied new and backed by a three-year manufacturer guarantee.

Sustained output across both ports

Under continuous load the charger delivers a combined 3.4A at 5V, so two phones can charge simultaneously without the current dropping off after a short burst. The circuit maintains a steady voltage across the 100 to 240V input range, preventing the slowdown that occurs when lesser adapters overheat during extended sessions.

Replaces single-port USB bricks

It upgrades from older single-port chargers that force users to swap cables or carry multiple wall warts. The jump is worth it when you regularly charge a phone and a tablet together, or when a household shares one outlet for several devices. Buyers who need more than two simultaneous ports or a higher total current should look at multi-port desktop chargers instead.

Questions about this item

How much heat does the 3.4 A charger produce when left plugged in all day?

The adapter draws power only while a device is charging; with no cable attached it consumes negligible standby power and stays cool to the touch.

What must I already own to use the dual USB wall charger?

A standard US 100/240 V AC outlet and the USB charging cables that came with your phone or tablet.

Will the 5 V output charge an older phone that only accepts 1 A?

Yes — the charger negotiates the correct current so legacy devices draw only what they need.
