Wireless Boombox Tube Speaker System

Can you charge the pbmspg11 with a DC 5v charger

Yes

1) can it use micro SD card ? 2) when I use USB to play, it only plays the first and last song on the USB, repeatedly. It misses out all the songs in between. The forward or advance button does not work to go to the next song.

This unit is not equipped with a Type A USB port. Audio connection is only through 3.5mm Audio cable or VIA Bluetooth

I am looking for the charging cables and aux cable kit if there is one, for pyle boom box

For AUX cable please check this link:

My Pyle pbmspg11 always defaults to the Bluetooth setting... and I'd like it default to the Aux (line in). How to lock in the AUX/line-in as default instead of Bluetooth...? Mine just sits there looking for Bluetooth until I manually change it to AUX, but the speaker is not easily accessible to switch/toggle between AUX/Bluetooth.

Simply connect the AUX cord

I would like to use the AUXIN option, and the instructions provided indicate to "Press the MODE button" to switch to the appropriate mode. There is No button... where is this located.

Just plug in straight a 3.5mm Aux cable to the AUX port and connect your external sound source and play directly without any touch of a button

I bought a Pyle Portable speaker with the radio feature is there an app I can loan so I know what stations that are being picked up

Your phone has a radio app that you can connect to the speaker via Bluetooth

IM wanting a longer charging cord: usb on one end but what do you call the other end ( plugs into the unit) thx...z

How many hours of play before charging?

2 hours charging

Can I play what is on my my flash drive through the USB port of this speaker?

Unit is only for Bluetooth and AUX connection

Is okay to use a battery accessories. 5 volt when the unit is on.

Yes you can use it that way

How do I reset my PyleUSA PBMSPG11 so I can have it be linked to my computer via Bluetooth?

Turn off the Bluetooth of all devices that you have connected to the PBMSPG11. Then pair your computer.

How long will this battery last

The battery life is approximately one hour, depending on the volume level at which the speaker is played.

Where is the mode button on this speaker so I can switch to auxiliary jack? I'm using this as a guitar amp...

There is no mode button
