My BC model 16WMSO7OD-SLV won't charge and the Led wont light up either, I havent had it a full week but didnt use it on the weekend. Now I need it for tomorrow and it wont charge... Help!? The built-in Li-ion battery has a 2.500mAh capacity. It is advertised that you can get 16h at moderate volumes. In reality, you won’t get that much. At full volume, if the lights are on, you will get less than 3h. Soundcore Boost has a powerful 5.200mAh battery. The battery delivers up to 12 hours of playtime and the USB powerbank port allows you to charge your phone while listening to music. There are many amazing speakers on the market but we truly believe that JBL Charge 4 deserves the opening position on our list of 5 best portable Bluetooth speakers with USB ports in 2023. It’s not cheap but also not unreasonably expensive. The speaker is available in plenty of attractive colors, it has a quite long battery life , and great audio reproduction. To top it all, this speaker is completely waterproof , which makes it a great companion at different outdoor parties, gatherings, etc. Things we like

The speaker houses two front-firing 10W drivers and a passive bass radiator between them. It delivers surprisingly loud sound with punchy bass, sweet midrange, and slightly elevated treble. If you prefer bass-heavy sound, you can press the BassUp button and elevate the bass response. Things we don’t likeIf you’re familiar with Bose equipment, you’re probably aware that they don’t really offer much info about the internal components and other specs. We don’t know what Bluetooth version they used but it works pretty great. You can pair the speaker with your phone the old way or you can use the NFC. Both ways are pretty fast. The connection is stable within the 30ft range. The speaker can memorize up to 8 phones and two phones can be connected at the same time ( multipoint pairing).

This device must accept any interference received. including interference that may cause undesired operation Edit: It worked! After 2 hours of charging, the green light on adapter turned off and now to test the speaker, I have been listening to good music for good half an hour on battery. The speaker has an equalizer for indoor and outdoor modes, allowing you to adjust your audio signal and find the right balance. It also has NFC connection that allows you to pair your smartphone with your portable speaker by simply touching it (NFC Only for Android). The W-King D8 has supported advanced Bluetooth 5.0/AUX/TF Card & hands-free calling, with a wireless connection range of 100ft, creating a fast and stable signal transmission.

Despite the built-in equalizer, we wouldn’t recommend this speaker to people looking for a bass-heavy device. If you need the kind of bass that overpowers everything else, you should keep searching – this isn’t really the speaker for you. After reading article on internet, I found that batteries can be charged with normal direct current too. It is just given the charging took 2h, that time should not be exceeded as there would be no stopper when battery is full. First I plugged in a USBC into a wall adapter and the other USBC terminal into the speaker. It didn't work.
