Most Chromebooks feature excellent battery life. As a matter of fact, ChromeOS laptops don’t have a built-in battery saver simply because they don’t need one. But if you’re on the go and you need to use your Chromebook for more than 8 or 10 hours, you may run out of battery power at some point. If there’s no power outlet around, you can use a portable charger to keep your laptop alive.
Charging Your Chromebook with a Portable Charger
Check the Input Charging Speed
Before buying a portable charger, check the input charging speed that your Chromebook supports. The information is available on the bottom cover of your laptop. Most ChromeOS devices support 30W or 45W, but other models may support a different charging speed. Newer models support 65W.
Will the Portable Charger Steal Charge from My Chromebook?
Many Chromebook users are reluctant to use portable chargers, fearing the charger could actually steal charge from the laptop. Well, if you’re charging your laptop long enough, your power bank will begin to “recharge” off of your Chromebook.
When you connect a portable charger to your Chromebook, the two devices assess each other’s capabilities. Then, they negotiate for the power they need. Simply put, your Chromebook will “talk” to your portable charger and then decide who should charge who.
If your Chromebook is running low on battery, it will refuse large power requests. Your portable charger will also limit its charging requests when talking to a laptop. So, there’s really nothing to worry about. But if you want to be absolutely sure, simply unplug your portable charger when your Chromebook battery has reached 80 or 90 percent.
How Long Does It Take for a Chromebook to Charge with a Portable Charger?
Charge time depends on your portable charger’s capabilities. For example, if your portable charger outputs less than 30W of power, you’ll still be able to charge your Chromebook but very slowly. Additionally, you’ll also get a “Low-Powered Charger” notification.
Keep in mind that Chromebooks require 30W of power to charge efficiently. Your Chromebook usually needs around three to four hours to charge from less than 10 percent to 90 percent using a portable charger. Of course, you can still use power banks with a lower output, but your laptop won’t charge at its max speed.
