How do you charge the Bats ? USB works in -out? I want to charge it with portable solar panel .

You can charge with it but it can't tell when the batteries are charged. It will keep on charging until you unplug it. You use the usb cord that came with it.

I purchased this also to charge on my back country backpack trips. I use a 7 watt solar charger. Price and weight were the criteria for both.

It does not have a USB connection buy I do know a company that makes portable panels with a USB connections for phones and small devices. Email me and I'll send you the link to the company that makes them since I think amazon wont let me post here it.

You charge the battery via the USB wire that you must keep and plug into any usb port. That charges the battery. There is no other method to charge the battery with house current, but it is not a problem. I have been using mine for about 9 months now, and the record player works great by itself. I have not been able to plug speakers into it and make them work, but it is probably just me. The charging system works fine, it takes about an hour to charge from the USB off of my computer. You can get an ac adapter to usb, and then plug your wire into that, to charge the battery. That would work too. Also a 12 volt adapter to USB port will work. The battery runs the record player for a long time, I have not ran out of power using it for half a day, so that part works fine. I recommend being very careful when you plug the wire into the side of the case, as the usb wire connector can bend the charging wires, I had to put on my glasses and straighten them out, as I mashed the wires into the connector incorrectly, thinking I had it in there the right way.

I'm not sure exactly what you have. Nearly all solar panels are set up in either 12 or 24 volt configurations for normal battery charging. Especially if it is a 9 Amp - 45 Watt Panel... I have a 45 Watt panel that at best only pushes 2.7 Amps and fluctuate between 10-17 volts depending on how much sunlight. At 5 volts you are probably talking about a USB charging panel for USB devices? If so your cell phone or tablet will have an on board charge controller... Ultimately, I think NO... this charge controller will not work for you. It needs either 12 or 24 volts into the controller to tell it how to charge the battery set up... Also, it has a non replaceable fuse inside. So if you blow the fuse, like I did, you are faced with either getting a different one, or trying to replace the fuse some how...

Anker makes some fairly nice USB batteries that you can buy on Amazon for under $50. You could use one of those batteries with the solar array and have power left three days later.

My unit came with a charger but only recharged the battery once before it stopped charging. The stun bat itself is very cool when you have a fully charged battery. The manufacturer really needs to provide a better charger. Thanks for asking the question because I forgot all about the thing and needing a new charger which should be free of charge.

There is a DC IN port that will allow the user to charge the battery while actively powering and using the device just like cell phones. In fact I'm doing it right now before taking my speaker to work.

If it actually works, charge with their proprietary special cable that plugs into a usb charger until it breaks. This item is crap; buy a VASS brand battery. It uses a standard mini-usb input.

Hey Edwars O. Not sure. What type/sort of system are you putting together? 6V 12V? What are you needing to run, and for how long? What are your energy needs? I can't answer your question my friend without more info. I personally use the 400 watt system with another 100 watt panel. I match my batt bank so every 100 watt of solar for 100Ah of storage. Yes, it is over kill for just myself! I'm still in the learning processes if you will. The panels that come with this kit have zero issues with charging the batteries on cloudy days. I'm very happy with this basic system so far!!

This unit does not charge via solar power for me. However, it is a very good portable charger when plugged in and left to charge. It will charge your devices very close to, if not at, 100% if plugged in.

The panel has been Modified , They are just Solar Panels with standard 2 wires out . I and others modify them and put circuitry and LifePo4 batteries in them and Cut holes for Outlets and usb charging. The cost to do this is around 350 dollars and a lot of time but the results are a Self contained 110 volt ac portable Soln1 .

The panels do not hold a charge themselves. You can charge directly from the panels or connect an external battery (not included) and charge that as your future power source.

I think they make one now that has a USB port. Mine is older model. Can't charge anything. Also if you just looking, I wouldn't get this. The solar panel takes forever to really charge. And radio or flashlight only works couple of minutes

There are two ways to charge up your battery pack. One way (slower) is to use a USB cable from your computer to the battery pack (computer has to be on). The best way is to get s USB to Mini cable and an AC adapter that plugs into an outlet and has a USB opening. Listen if you go to Amazon.com lookup the Battery Pack you will see "other items purchased" that adapter I mentioned will be listed. Good luck

I agree with the other two answers, I had to charge mine for a few hours with USB cable provided before it would work.

Like with most solar-powered charger, you have to charge up (at least partially) the internal battery first, before you can use it to recharge external USB devices. The current from solar panel (300mA best case) is too small to drive most USB devices directly, as they typically require 500mA - 1A. The solar panel output is also at the mecy of sunlight. That's why the internal battery is needed as an energy buffer.

I also bought a jacket and batteries. I have not tried anything yet though. My jacket came with a USB adaptor that snaps on the battery. I understand that the jacket plug is not a USB connection, I thought there was a plug connection on the side of the USB adaptor for the jacket power cord
