2B Bonus Pack

If you are an experienced E-Stim user, and you want the best, or if you are a beginner but you believe in investing in the best right at the start, then the 2B Bonus Pack is for you. We have taken our highly popular digital electrostim power box the 2B, and added our 2B Accessory Pack together in one Bonus Pack for you.

What do you get?

We always try to offer you enough accessories to get you started. The 2B Bonus Pack is no different. You get everything you would normally get with the 2B, plus everything in our 2B Accessory Pack. So in addition to the cables and sticky pads you get in the 2B, you also get two 4mm cables for you to connect any of our premium electrodes to your new 2B, the Universal Mains Adaptor and the Digital Interface Link.

Power Box

The 2B power box. An advanced power unit, with dual isolated output channels, 17 program modes, built in audio, as well as the ability to connect to a PC, Mac or over the internet via the included digital link system.

E-Stim Systems Digital Link

Digital Link

The Digital Link System allows you to control your 2B from both a PC or a Mac with Commander 3, and even securely over the Internet with our award winning E-Stim Connect System. The UpLink system also allows you to upgrade your control unit to the latest Firmware. UpLink and Commander 3 are supplied on a USB memory stick. The Digital Link System also allows you to try out the latest firmware, even before its available for general release - see https://www.e-stim.net for more details.

What is the difference between the 2B Bonus Pack and the Standard 2B?

The Standard pack does not include the Universal Mains Adaptor and Digital Link, these are optional extras. The Standard Pack also only comes with 2mm Cables for us with the sticky pads but the Bonus Pack also includes two 4mm cables for use with our range of Premium Electrodes.

Do I still get a Lifetime Guarantee?

Yes. All of our power boxes are covered by our Lifetime Guarantee.
