An adequate JBL Charge 4 Charger supplies enough power to charge this speaker in the shortest time (around 4 hours). Note that currently, JBL does not include a USB charger with this speaker. So, you’ll need to either have one already or buy one.
Also, the speaker has a USB-C charging port. So be sure to have the right USB-C cable on hand.
Furthermore, the maximum current this speaker accepts is 2.3 amps, and this gives the fastest charging performance. So you’ll get that whether you use a USB-A or USB-C charger. But just be sure to get the right cable, depending on the charger you have.
Which JBL Charge 4 Charger Works Best?
We’ve successfully charged our Charge 4 speaker with the AC adapters we list below. Note that some of these feature a USB A type female connector. So, AC adapters like these work if you use the USB-C to USB-A cord that comes with the Charge 4. But if your charger only has a USB-C output port, you’ll need to get a USB-C to USB-C cable.
Now, to the chargers we suggest.
USB-C Chargers that Work Well with the JBL Charge 4
This group of chargers can recharge the JBL Charge 4 at the max power (11.5 watts). Plus none of these is very much money. But for most of them, you will need a USB-C to USB-C cable to connect to the speaker.
