USB-C battery packs are starting to get more powerful, and simultaneously less expensive. This new model from RAVPower includes a 45W port for just $48 (with promo code LKWZQ4C3), whereas most that we’ve seen to date have been limited to 30W.
That means you could charge a Nintendo Switch, a MacBook, or a MacBook Air at full speed, or a 13" MacBook Pro at nearly full speed. And with 20,100mAh onboard, there’s enough juice here for full day away from an outlet.
