Two-port 5V 2.1A USB-A charger for everyday devices

This Uenlio TP249 wall charger supplies up to 2.1 amps from two USB-A sockets. It suits phones, small tablets and other low-power gear that charge from a standard 5 volt source. The pack contains two identical black cubes for home, office or travel use.

Total 2.1A limit means shared current when both

The 2.1 amp rating applies to the whole adapter, not to each port individually. Plugging in two devices splits the available current, so charge times increase. If combined draw exceeds the limit, overload protection shuts the unit down until the load is reduced. Sequential charging avoids the restriction entirely.

Fingerprint-textured shell plugs straight into any

No cable or extra parts are needed; the prongs fold or fix directly into the mains socket. The textured sides improve grip when inserting or removing the cube. The only common issue is the shared 2.1A ceiling, which can trip the safety cut-out if two hungry devices are connected at once.
