Why hello there! For your question about using devices while plugged in, I'd recommend taking a closer look at the portable power banks and chargers in the results. The Xiaomi Mi 20000MAH Power Bank and ANKER Powercore 26800 in particular would allow you to keep devices running for extended periods away from an outlet. With their large capacities and fast charging capabilities, they're great for maintaining power on the go. Just be sure to check compatible charging speeds for your devices. Let me know if you need any other recommendations!
