Ideal for your home or office workstation or travel use, the TLP28PD57WCAM features a surge suppression rating of 300 joules to defend your sensitive electronic components against power surges and spikes. Plug your laptops, projector, printer and other conference-table electronics into two NEMA 5-15R outlets to protect them against dangerous surges, spikes and line noise. The outlets are spaced widely apart to accept bulky transformers without blocking any outlets or ports. Two USB-A ports are available for charging your smartphones, tablets and other USB mobile devices. They share 4.8A of charging power, which is plenty for delivering ample power to demanding devices. A USB-C PD 3.0 port delivers 45W of charging power for laptops and other larger devices. All three ports share 57W maximum.
