We recently tested out our top-recommended USB-C battery, the Anker PowerCore+ 20,100 with the Samsung Chromebook Plus. Reports had been great on its use with a variety of USB-C phones, laptops, and tablets, but we wanted to see how well it would work with the latest Chromebook from Samsung.
Anker PowerCore+ 20,100 USB-C External Battery
Our assumption is that a laptop user who carries an external battery would like to use that battery to keep working/playing once the laptop’s own battery gives out.
We thus ran the battery on a Samsung Chromebook Plus down to zero, until the unit turned off. We then attached the fully charged Anker Powercore+ via a USB-C to USB-C cable. (It’s important to push the button on the Anker before doing this, as this tells the battery to charge the connected device, rather than attempt to draw power from it.)
Once connected, the Chromebook Plus could be powered on. The battery indicator on the Chromebook showed (see photo at right) that it was connected to a “low-power charger” and indeed the recharging was slower than if the Chromebook had been connected to a wall outlet.
The Chromebook Plus would obviously charge faster if it were powered off, but we were more interested in seeing how it would do if we were using it (if stuck on a long flight, a marathon work session in a coffee shop, etc.). We thus continued to use the laptop for low intensity tasks (writing for this website, listening to music) while it charged.
Still, as we reported in our main review, the Anker PowerCore+ remains the best USB-C external battery option for now, and gives quite a bit of backup power and autonomy for most normal USB-C laptop, tablet, and phone use.
