Standard USB chargers put a 60 Hz electric field onto the cable and device. This charger drains induced voltage from the USB cable to ground, with three grounded AC outlets and three grounded 5V USB ports.
The USB ports share 12 watts in total, so it suits phones, tablets and headlamps. It is not a surge protector. Black or white.
Frequently Asked Questions
Why does it charge more slowly than my usual charger?
The three USB ports share 12 watts in total, and the unit is built around a grounded, reduced-field charging path. Slower charging is expected, not a defect.
Can I charge a laptop with it?
No. It is made for low-power 5V USB devices such as phones, tablets and headlamps. For laptops, see the SafeCharger Hub 45 (up to 45 watts) or UltraMac 63 (up to 63 watts).
Is it a surge protector?
No. It is a grounded charger with three AC pass-through outlets, and it is not designed as a surge protector. For surge protection, see the eShield 9-Outlet Surge Protector.
Does it work in an outlet without a ground?
No. The shielding drains through the ground pin of the plug, so an ungrounded outlet gives it nowhere to send the field. A plug-in outlet tester from any hardware store shows whether an outlet is wired correctly.
