Most of the units we’ve tested split this current over two ports, which means that if you plug in two devices, they’ll each charge at less than half their maximum speed. We prefer that each port be rated for at least 2.4 amps-which is what most phones and tablets require to charge at full speed-but such ports are relatively rare. The Power of the Dog is based on a 1967 novel by Thomas Savage, a closeted gay man whose critically acclaimed fiction drew on his formative years living and working.

USB charging: Since many devices and accessories charge via USB, we limit our search to power strips with USB ports, which helps reduce the number of wall warts you have to pack.

We call out models that can serve as true surge protectors, but if that’s your main concern, you need to invest in a larger option. Most portable models, though, let through more than 1,000 volts. Here’s what some of the positive reviews of The Power of the Dog have to say: Empire: Cinematographer Ari Wegner captures the vistas of Campion’s native New Zealand, doubling as Montana, in lucid, breathtaking detail, while Jonny Greenwood continues his journey as a maverick composer, bookending the narrative with scuffed, low guitar. In other testing, we’ve found that many electronics can survive a 400-volt hit-the amount that most home surge protectors let through when struck by a 5,000-volt surge.

What really matters is how much voltage from a surge makes it through the outlets. The joule rating on the box gives you some indication of how long a model will take cumulative surges, but not how much power could hit the gear you have plugged in. Surge protection: Most portable power strips are too small to include meaningful surge protection.
