Dell Power Companion is one of two solutions designed to let you power your laptop and other devices on the go. It’s compatible with select Latitude, XPS, and Inspiron systems and simply plugs into the laptop’s charger, then into the system itself.
There are a couple of regular USB Type A ports that expend 2 amps and can charge a pair of smartphones or tablets at the same time, plus an input that’s compatible with most Dell power bricks. But the big selling point is that this thing can fully charge from zero in just a couple of hours. That’s a huge advantage over generic battery packs that typically take a half day or more to recharge from empty.
This thing maxes out at 65 watts though, so it won’t be able to keep up with a more powerful laptop that needs more power for its graphics or processing cards. It will however, be able to supply enough juice to help you keep working for an extra hour or so until the battery savings kicks in.
This is a fairly large and heavy power bank companion that’s not the most portable solution out there, but it does have its merits. It’s relatively cheap, generously sized, and fairly compact, although it can’t match the raw power of more expensive alternatives like the above Anker option. It also doesn’t come with its own wall charger and doesn’t have a USB-C port, but those are pretty standard drawbacks for such a low pricepoint.
