Kit Contents

This 4XEM kit combines a black AC adapter rated for 10W maximum output with a 6ft Micro-USB cable. The adapter delivers 5 V DC at 2 A, making it suitable for any USB-powered device that accepts this voltage and current.

Sustained Load Behaviour

The adapter maintains a steady 2 A output without the current taper seen in lower-rated chargers during prolonged charging sessions. Heat dissipation is handled by the compact enclosure so the unit remains safe to touch while supplying continuous power to phones, tablets or other USB devices.

Micro-USB Interface Limits

The included cable terminates in a Micro-USB connector, so devices that require USB-C, Lightning or proprietary ports cannot be used without an additional adapter. Maximum power is capped at 10W, therefore equipment that negotiates higher voltages or currents will charge at this lower rate only.

Questions about this item

How much heat does the 10W charger produce when left plugged in all day?

At 5 V DC and 2 A the adapter draws little power, so it stays cool during continuous use.

Which cable or device must I already own to charge with this kit?

The kit includes a 6 ft Micro-USB cable, so any phone or tablet with a Micro-USB port works immediately.

Will the 2.1 A output charge my older Samsung Galaxy S3 or S4 as quickly as the original charger?

Yes, the 5 V DC 2 A rating matches the stock chargers supplied with those models.
