Speed up your VPN connection with the VPN Accelerator 

Speed up your VPN connection with the small and exquisite VPN Accelerator ™ 4.0 (VPNA) which offers state of the art performance and technology in an incredibly compact unit. The latest Intel Core processor guarantees you exceptional power to enjoy your VPN network with increased speeds and silent efficiency. The VPNA brings ease of use and convenience like never before.  

The VPN accelerator works with routers configured with Sabai OS out of the box, and most other firmware with a bit of configuration.

Features Include:

  • Improved Diagnostics & Performance

  • Proxy Server

  • Optimized OS

  • Increased Flexibility

  • Intel Integrated Components


Users can use the high speed connection of a VPN Accelerator while controlling their connection through a web browser proxy settings. No more logging into the router interface every time you want to change between Local and VPN.

Using Gateways, you set up a laptop in your home as a "local" device. This means that local traffic, as opposed to VPN traffic, is fed to this device over the Wi-Fi network. While you use this computer mostly for local internet, you sometimes want to access foreign internet and browse privately. Proxy allows you to use VPN on a certain program keeping everything else on the computer connected to the local internet.

Previously, you would have used our convenient Gateways feature by logging into the VPN Router and switching the entire device from "local" to "VPN."


Customers love using the VPN Accelerator to increase the usability of their VPN network so our developers decided to take a great product and make it even better. The addition of a VPN Accelerator to your VPN setup brings a major speed upgrade to your connection. This makes it perfect for streaming HD content from overseas that would otherwise be blocked or throttled.

Add to this the fact that you have a private connection that can’t be spied on, and you have fantastic functionality at previously unheard of speeds.

See what all the fuss is about and experience faster VPN speeds with Sabai Technology's VPN Accelerator today!

The VPN Accelerator can increase your VPN wired or wireless network speeds by as much as 500%.** **Speed improvements vary by router, local internet speed, location, distance to router, and ISP throttling.**


A simple speed test can be the best indicator of the likely speed enhancement. To perform this test, run your VPN account locally on your computer using your VPN providrs desktop application and complete a speed test via speedtest.net. The speed results from running VPN directly from the computer will be a very good indication of the new network speeds you will experience with your Accelerator. Still not sure? You can run more advanced speed tests or contact our support team.

  • Apple TV

  • Smart TV

  • Boxee

  • Slingbox

  • Xbox

  • Wii

  • iPhone or Android smartphone

  • Computers and Laptops

  • and more ... all at once, from one VPN account.

Will it work for me?

The VPN Accelerator is designed to work for customers who have a relatively high local speed and whose ISP does very little to throttle external connections. The best test for what kinds of speeds you will receive on the VNP Accelerator is to run your VPN service directly from your computer and run a speed test. If you would like, there are some advanced speed tests that can also be run to indicate if you are a good candidate for the VPN Accelerator.

Does it work on DD-WRT?

The VPN Accelerator was created to work specifically with Sabai OS, however, with some manual setup and configuration, the VPN Accelerator can work with any router. If you enjoy your DD-WRT router for VPN, you will love Sabai OS for all its advanced functionality and features. Plus, the setup is incredibly easy compared to DD-WRT.

How to reboot the VPN Accelerator

If you experience issues with your VPN Accelerator, the first thing to do is reboot. If you need to do so, follow these instructions:

  1. Turn off the accelerator (press the power button, do not unplug)

  2. Set the Sabai router Gateways default to None

  3. Reboot the router

  4. Restart the accelerator, check that the VPN has connected

  5. Set the Sabai router Gateways default back to your choice

If you’re still having issues,  Feel free to talk with one of our Technical Support Technicians.

    Sabai VPN Accelerator

    Posted by Matt K. on Nov 2nd 2018

    Gained 4-5 times speed compared to my vanilla OpenVPN on WNR3500/Tomato. Absolutely recommend this if your VPN is significantly slower than your non-VPN service... takes all the heavy processing work out of your router... genius. Also, great support staff... can't go wrong with Sabai.

    A great buy

    Posted by Dave B on May 10th 2018

    I was unsure at 1st if this would make a big change, well it did. I went to 30mb over my VPN to over 130mb. Well worth the price!!

    Great boost

    Posted by Unknown on Oct 21st 2017

    After installing the VPN accelerator, I went from an average download speed of 25 MBps to 160 Mbps. Once I connected it, I reached to my VPN provider and had it running in a manner of a few minutes. Wish I had done this sooner.

    Great addition to my existing Sabai router

    Posted by Ahab Shamaa on Apr 18th 2017

    I bought the VPNA thinking it would increase my VPN speed by 2 or 3 Mbps. You can imagine how happy I was to discover that the VPNA added another 8 to 10 Mbps to the VPN speed! I am now getting around 17 to 18 Mbps, and I couldn't be happier. Streaming TV is now seamless with no buffering whatsoever.
    Ruth from Sabai helped me set up the device, and she made the experience all the more enjoyable with her great customer service skills and her deep knowledge of networking and VPNs. I highly recommend the accelerator to anyone looking for additional VPN speed; especially if they're going to be streaming live HD TV.

    Five stars for product reliability & customer service

    Posted by Arturo Ordonez E on Feb 7th 2017

    I have been a customer for years, and when a company puts their customers in 1st, they always succeed.

    With the accelerator, I'm getting like 98% of my contracted speed in my local country, a 48 mpbs of download speed with a latency of 50's ms, is amazing..!

    Worth the Upgrade

    Posted by Paul on Jul 7th 2016

    I pre-ordered the new VPNA after having used the previous model for 2 years. Our local internet in Cyprus is unstable and a VPNA is a must for streaming TV. Wow, this new model has improved the stability even more, we no longer experience the VPN dropping off and the HD picture quality has improved greatly. I cannot fault Sabai for their products and technical help, they are simply the best. We did have a slight problem setting the new VPNA up, but Ruth came to the rescue and sorted our issue in a few minutes. Customer service as it should be. I would not hesitate to recommend any Sabai products.
