DP-4000 Digital Maximizer Review

DP-4000 Digital Maximizer is a programmable electric air pump that is not as popular as its competitors, but it’s effective for penis enlargement as well. This pump is not a water-based so you’re given a higher limit of operating pressures.

Brief History

DP-4000 is manufactured by CTC Company. This US-based company has been in business for over 45 years and is specializing in designing penis enlargement products.

CTC Company currently has four different products on their website, DP-4000 being the latest pump.

About the Productdp-4000 maximizer pump

Air pumps like DP-4000 can yield up to 1.5 inches growth within the initial 1-3 months of usage. It is carefully designed to provide controlled pulsation in order to allow the penis to expand and stretch to its maximum capacity.

DP-4000 produces an erotic sensation to the user as a training to avoid premature ejaculation, thus leading to a stronger stamina. Its changing vacuum environment promotes better blood circulation. This makes it easier for the body to supply more blood to the penis. As a result, the user will be able to maintain a harder erection.

This pump allows vacuum levels from 1 Hg. to 15 Hg, including 10 vacuum presets. The product has a 1-year warranty and the company provides free lifetime software updates.

DP-4000 can be described as an old product when compared to similar electronic air pumps that have just been released recently. This product requires the user to connect it directly to the computer in order to manipulate the settings of the machine. The last software update for this product was in 2012 so it could be outdated.

It’s a game changer

 by 

I have multiple manual pumps at home. But DP-4000 beats them all. Getting my own machine is like taking the plunge. It is pricey, but when I got my hands on it, I was able to tell myself “I wish I had gotten this sooner”.

Not recommended for someone who plans on using it while traveling, though. It is smaller than expected but still, it would be a hassle when you have to explain to the security what that device is for.

I am using a MAC, so I had to download a virtual machine to run a windows program. It’s not very convenient but I am glad the program was set up quickly.

Compared with a manual pump, I would always choose my DP-4000. The fact that you can program your pumping session is enough to choose it over a manual pump.


It may take years to set the best pattern

 by 

I have my DP-4000 since 2012. For 5 years, I gained 1.5 inches from regularly using this product. It took me about 2 years to create the pattern that I stick with until now. It takes trial and error to set up what pattern suits you.

That can be hard for some, but if you are as determined as I am you will be able to find the perfect pump that suits your lifestyle.


Louder than a horn

 by 

It’s funny how this product is so noisy I could actually wake the neighbors when doing it during the night. Now my sessions depend on when my neighbor is awake or asleep. I decided getting some soundproofing ideas just to be able to enhance my size. I am still about to find out whether this product works for me.


Be careful with this product

 by 

This product is very powerful that you can easily have a doughnut. I was using it for almost 3 weeks already when I figured maybe I could try to see my limit. I guess I pumped for too long using a high pressure.

I was so shocked that my penis got swollen so easily. I was traumatized at first, so I stopped using this for a while. I started a new session with it again just recently and only used the low pressure.


You get what you pay for

 by 

I have been trying to gain for about a decade now, and I can say that I have tried all the other cheap alternatives out there. DP-4000 poses a risk because of its huge price. But the cheap ones don’t really work well for me. This automatic pump is not very tedious to use. It is noisy but worth it.

How to Use DP-4000

  1. The product does not come with a cylinder so you will have to purchase one from another source. If you don’t have any, it is important to measure your penis properly in order to choose a cylinder that fits you perfectly.
  2. Follow the manual for assembling the device.
  3. The product comes with a software that connects to the device through your computer. The software has 10 vacuum level settings, 10 step points and a threshold for controlling the pulse sensitivity. You will need to set these up according to your comfort level.
  4. For starters, it is safer to start at the lowest vacuum level and gradually increase it by 1 Hg.
  5. After setting up your preferred routine, you can save this as a preset to your computer so you can just quickly reload on the next use.

Safety Precautions

  • Avoid pumping for more than 5 seconds when you are using 7 Hg vacuum levels.
  • Continuous pumping for more than 30 minutes may lead to swelling or doughnut effect.
  • It is recommended to alternate between low (2 – 4 Hg.) and moderate vacuum levels (5 – 6 Hg.) so you can pump longer while avoiding the negative side effects.

What’s in the Box

The complete system includes the following items:

  • Digi-pump
  • 12-volt wall adapter
  • 6’ USB cable
  • Digital maximizer software version 2012
  • 10’ connection line
  • Instruction manual
  • 2-quick connectors for any cylinder

Requirements

  • Operating system: Windows XP / Windows Vista / Windows 7 / Windows 8 / Windows 10
  • Power: 115 volts or 12 volts / 230 volts for overseas customers

Pros

  • Programmable settings. Decide how long you want to run the program, what vacuum settings to use and their time intervals, and the maximum pressure you want to apply. No need to look for a gauge to check pressure or squeeze the handle to increase vacuum.
  • Great for multitasking. If you use a long tube that connects the cylinder to the electric pump, you can do other things (like using the computer).

Consdoughnut

  • Noisy. You can’t use the penis pump discretely.
  • Injury risks. DP-4000 can generate very high pressure, which could lead to a “doughnut effect”, the excessive swelling of the penis glans and foreskin.
  • Long learning curve. It will take time to come up with a balanced program.
  • Too expensive. Price is way higher than other electronic air pumps as well as manual pumps like Penomet and Bathmate.

Where to Buy

The pump is currently available for purchase on their official website, eBay, and Alibaba for 469.00 USD each.

Returns and Money Back Guarantee

CTC does not specify any money back guarantee, but their eBay store states that they do not accept returns.

Conclusion

DP-4000 proved effective for some men. However, because it is expensive, outdated and uses old technology, we recommend using other option for pumping. See our article for a complete list of recommended pumping tools.

Past Reviews

The following are old reviews for DP-4000.


Not very user friendly

 by 

I have my own DP-4000 but I can’t get to set it up in my laptop, although I was able to get it working using my old computer from before. I can’t figure it out, but I can’t access it using any laptop.

I am able to see the program from the software, and it seems fine from the laptop, but only the machine doesn’t seem to be able to read the program when connected to a laptop. This is still not fixed and the customer support is not very helpful with this.


I would recommend it

 by 

If you have the money to buy a product that is worth it, I’d say go with DP-4000. It works, and I gained about 2” in girth and length after using it for 2 years now.

Aside from pumping, I also have Jelqing and stretching routines. You get what the website promises – it is automatic, with programmable pressure and timing. I use it all night in low pressure. During the day-time, I have a short routine for using it in high pressure.


Too noisy I can’t use it

 by 

I have been trying to hide doing my PE’s from my wife but it is impossible when I am using DP-4000. It is just too noisy that I can’t do it whenever she is around.

I bought a manual pump to replace it and now I am back on track. It’s just a waste seeing it lying around and not being used.
