Frequently asked questions
Which radio keeps working when the battery is empty and the sun is gone?
Both have a hand crank. The Kaito Voyager X also takes four AA batteries so a fresh set restores radio and light at once. The Midland ER310PRO lists no AA backup and relies on its 10,000 mAh pack. Its larger reserve means that moment comes much later.
Does the Kaito Voyager X charge phones as well as the Midland ER310PRO?
Both charge a phone. The Kaito Voyager X offers USB-A and USB-C outputs plus a wireless pad on top. The Midland ER310PRO uses one USB-C Power Delivery port and holds twice the charge. Expect more refills from the Midland ER310PRO and more ways to connect from the Kaito Voyager X.
