Despite all battery saving attempts, this thing leaves me worried to go anywhere that I cant plug in. And, this day and age, needing to carry the stupid cord around is Ludacris. ZERO complaints otherwise; great little device. I also own a Lenovo thinkpad, which has USB-C charging; meaning i can take a power bank or other to charge on the go... This.. nope. I should have went for another chromebook, i think.
