## Customer Reviews

### ⭐⭐⭐⭐⭐ Very good power supply!
*by M***Y on June 7, 2020*

I wanted to write a review for this since there isn't a lot of good information out there.First off, the ProJect documentation is extremely simple/minimalist and contains some translation ambiguities particularly in the "Charging" subsection within the Output section. Here is an excerpt from the manual to show you what I mean:-----------"Charging"- is illuminated when batteries are charged.- is blinking when battery status is low (20%) - charging is not in progress. If the charging is not startedmanualy by disabling the output sockets it will start charging automatically when battery status is below10%-----------Here is how it should read, based on my usage of the product:+++++"Charging"- is illuminated when batteries are currently being charged.- is blinking when battery status is low (20%) - charging is not in progress. If the charging is not startedmanually by disabling the output sockets it will start charging automatically when battery status is below10%+++++That's a small change, but is much more clear. The second bullet point also sort of implies that once your battery is down to 10%, the device will disable the outputs and begin charging. This was the main thing I was curious about prior to purchasing. However, the device does not disable the outputs at 10% charge. You can still play records (or whatever) uninterrupted while the batteries charge.They do not mention how long the battery life is, and I expect thats' because this can power all sorts of products with varying results. I'm using this to power my ProJect DS2 TubeBox. I get the 20% warning/flashing after around 4 hours of playback. After another hour or so, the Charging light is solid and it will charge on it's own (even while in use) up to 100%. If you disable the outputs when the batteries are less than 100%, it will begin to recharge. Even in that state, you can re-enable the outputs and keep on playing.I'm using this to power the aforementioned ProJect DS2 TubeBox, which is getting signal from my MoFi UltraDeck, going to a Marantz power amp. I have to say, all of the sonic qualities that Project promises is 100% real. "Using Accu Box S2 on any of our recommended products, results in a more homogeneous and spacious sound with better separation and imaging. The sound will come across as more cleaned up overall, giving you a relaxed listening experience with mind numbing sonics."A big plus for me is the removal of the AC line noise from dimmer switches (and other things) in my house, which is now completely gone after integrating the AccuBox S2.This is a fantastic product and I would recommend to anyone that already has some quality gear!

### ⭐⭐⭐ More Battery than Power Supply
*by M***X on February 16, 2022*

I bought this to hook up with a Tube Box S2 and the Head box, thinking that if it is plugged into the wall the entire time then it will play for hours, I didn't realize it is just a battery. Even plugged into the outlet it won't go more than 2 hours before dying out and needing to recharge. So the time listening is limited especially if you are trying to power more than 1 device. The plug that goes into the outlet is poor quality as well and I am looking for a replacement. I haven't been able to find better 18V Pro-Ject power supplies for this thing, so looks like I'll have to go third party for that.

### ⭐⭐⭐ Austrian confusion
*by T***  on November 19, 2020*

As most are aware there aren’t many reviews (particularly English reviews) of this product. I have several Pro-ject devices and the first thing you should know is the power sources for these are complete rubbish. Countdown to replacement. The connecting cable will also need to be replaced(2.5 to 2.5 included). I recommend third party. The devices themselves are of exemplary build quality. The review above proved very helpful. The directions will not. It’s unlikely you will be able to connect this to more than one device (that is the job of Power Box DS $799). It does it’s job as advertised, albeit in a very subtle way. I honestly think it should cost about half of what it does, however, they have few competitors at 18v.
