I got this specifically for the mp3 player aspects. It does have 2 outlets and a dc cigarette plug, though. I got such a killer price on auction that I figured if it sounded bad, I could still use it for a dc fan while camping.

I have a larger powerpack and I'm familiar with how they work. The instructions clearly state that the power remaining readout is NOT accurate until the unit sits idle and unplugged from anything for at least 15 minutes. The display while the unit is on is specifically stated to be used only as an estimate.

About the sound quality: I like techno/industrial/IDM. It is sometimes heavy on the bass. I have found the sound quality for my genre to be completely adequate. It is not my home stereo, but it does sound better than a boombox that I paid more for. The louder it is turned up, the worse the quality gets, as with most mid quality portable speakers. But, it has to get pretty loud for my ears to start balking at the noise. Really, it just doesn't sound that bad at all and I am pleasantly surprised, after having expected less. I plan to take it car camping and I won't be disturbing my neighbors with a too loud stereo, so this fits my bill perfectly.

The booklet says that the mp3 player has a minimum draw on the battery. I haven't played it till it has run out. I expect that it will run about 8 hrs or more. There are 4 speakers; 2 front, 1 each side. A flap on the front drops down to expose a recess where your mp3 player will be held with a large elastic band (I suppose it could just sit in there, too). You can use the line in to play the music or the usb to charge, or if your mp3 player allows, you can charge and play.

I plan to buy another for my daughter who lives on the beach. She doesn't want to take an extension cord to the beach and is sick of paying for batteries for a boombox that only plays cds. She'll be able to safely play her amplified mp3 player. Sweet!

I won't review the battery/powerpack itself. There are plenty of reviews under this model without the speakers. Just remember to keep it plugged in to maintain the battery with a trickle charge.

I had a hard time finding very many reviews for this. I hope this was helpful. Bottomline: Don't expect your home stereo. Think mid quality boom box. This is a great way to play all your mp3 music for a long time at a decent volume and with a decent sound quality.

I can't believe they are claiming that this unit delivers a good sound. It might be handy around the house, but get something else if you're looking for a portable stereo that sounds decent.

This is the best unit I have ever had. We own a campground and we carry it all over the place listening to music on our golf cart. Its very strong the sound is great very clean sounding. The battery last forever before you have to charge. Its nice to have as back up for electricty when needed. The lights are great for sitting around the lake and hearing music. The case its in is very strong. It is a heavy radio I don't recomend it for kids or elderly people.

Honest reviews on Xantrex Technologies 852-2070 XPower PowerPack Sound

This is a great idea, if only it would live up to it. I received this power pak and charged it for 48 hours as instructed. When I turned it on, it immediately dropped from 100 percent power to 90. When I plugged my mp3 player to it, it dropped to 70 percent before I played one song, and it went downhill from there.

The sound is terrible at any volume.

I figure the rechargeable battery was probably defective so I ended up having to return it.

The only pro to this order was Amazon's great service

The PowerPaqck Sound (PPS) is similar in design to the PowerPack SOLAR (no longer available). The PPS comes with stereo speakers and amplifier instead of the 4.5"X11.5" solar panel. I'm happy to have both units.

Since I don't care for MP3 Players I tested the PPS with my Sony CD player, my portable radio, and my 9" portable TV. For a portable system I think it's great. Really great. The AC outlets work and the plug-in to charge while the car runs also works. The lights work. I do wish they were independently controlled instead of both on or both off. They're on opposite ends of the unit. Anyway, everything that I tested works properly.

The instruction manual is straightforward and well written. It even includes instruction for charging with a solar panel. The PPA can recharge a cell phone (which I don't have), charge and power a tablet (which I do have), and either run/ or/and power other low power pleasurables.

One thing they left out was the ability to attach to a solar panel directly. This can be done with the addition of very small and inexpensive hardware (voltage controller?) and it is on other Xantex PowerPack units. This would also allow the unit to be connected to an outside battery for extra long utility between recharges.

The main thing I don't like is that the internal battery is not user replaceable. In five years or so, if I live that long, I'll have to check to determine if battery replacement by a local battery dealer is worth the cost. But by then Xantrex will probably have a better/stronger/lighter unit powered by rechargeable lithium batteries.
