JBL Battery 600 Replacement Battery And Charging Case with 45W USB-C Output - Black
The JBL Battery 600 gives your compatible JBL speaker a fresh source of power when the original battery runs low. Instead of ending the music, you can swap in the spare battery within seconds and place the depleted one inside the included charging case. Why stop the party when a replacement battery is ready to go?
Keep Your Compatible Speaker Playing Longer
Having a JBL Battery 600 nearby makes it easier to extend your listening time with the JBL PartyBox 520. Simply remove the depleted battery from the rear battery slot and replace it with the charged spare. Like changing a relay runner, the fresh battery takes over so the music can continue with minimal interruption.
The JBL Battery 600 can also replace the rechargeable battery inside a JBL Boombox 4 when its original battery begins to degrade. Therefore, you get an official JBL replacement designed specifically for compatible models.
Charging Case and Spare Battery in One Package
The included charging case lets the JBL Battery 600 recharge while it is outside the speaker. A full charge takes approximately four hours when using a JBL 60W power adaptor, which is not included.
The battery uses lithium-ion technology and provides a capacity of 21.6V, 4584mAh and 99.02Wh. Additionally, its supported operating temperature ranges from 0°C to 45°C.
Use the Charging Case as a Power Bank
The JBL Battery 600 charging case does more than recharge the included battery. Its convenient USB-C port also allows the case to work as a power bank for a tablet, laptop or smartphone. Need extra power for another device while you are away from an outlet? The case delivers up to 45W of maximum output power.
USB-C charging input supports 5V at 3A, 9V at 3A, 12V at 3A, 15V at 3A and 20V at 2.25A. Meanwhile, USB-C output supports 5V at 3A, 9V at 3A, 12V at 2.5A, 15V at 2A, 20V at 1.5A and 5–11V at 3A. A charging cable is not included.
Designed for Specific JBL Speakers
The JBL Battery 600 is compatible only with the JBL PartyBox 520 and JBL Boombox 4. Other speakers within the JBL PartyBox and Portable ranges use different battery requirements, so compatibility should be confirmed before use.
Because it is an official JBL accessory, the JBL Battery 600 is designed to work reliably with these two supported speakers. As a result, it offers a practical option for keeping a spare battery available or replacing a degraded Boombox 4 battery.
Compact and Portable Design
The JBL Battery 600 with charging case measures 103 x 43.6 x 137 mm, or 4.06 x 1.72 x 5.39 inches. It weighs 690 g, or 1.52 lbs, making it compact enough to carry alongside your speaker and other accessories.
The packaged product measures 152 x 57 x 118 mm, or 5.98 x 2.24 x 4.65 inches. Furthermore, the gross packaged weight is 790 g, or 1.74 lbs.
