Full charging times
The Ultimate Ears Power Up charging dock is designed to work with the Blast, Megablast, Boom 3, and Megaboom 3 speakers and each model takes slightly different times to charge on the Power Up. Here are the approximate full charge (from 0 percent battery power) times for each model using the Power Up:
- Blast: 2.5 hours
- Megablast: 3 hours
- Boom 3: 2.75 hours
- Megaboom 3: 2.75 hours
So no matter what speaker you have, you'll be getting comparable charging times. It's also fairly quick so you can get back out to the party, or whatever you were doing before your Bluetooth speaker died.
Is the Power Up worth an extra $40?
Yes. For most people, the Ultimate Ears Power Up is an invaluable accessory that will always keep your speaker charged and ready-to-go.
Much like a wireless charging pad for your phone, this is a much simpler and elegant solution to charging your device. Not only will the Power Up allow you to free up a USB port on your computer, but it also stays stationary, making it easy to set it and forget it. Plus, the Power Up takes up little space on its own. The dock is a small circle measured at 90mm in diameter. It's enough to just charge your speaker and nothing else, so little extra space is required. Its minimal design also ensures it'll blend in with any decor.
