Frequently Asked Questions

Why can’t I order a cable? Why is it out of stock? When will it be back in stock? Why is “ADD TO WISHLIST” my only purchasing option?

We are currently offering custom cable products for sale on a fluid schedule that you can check out on our Schedule page! We apologize if it is inconsistent, but we will try our best to announce upcoming openings as early as we can. The openings have been extremely short lately, so we further apologize if you aren't able to successfully get in before the orders fill up. We are working on it.

Please keep in mind that other products like DIY kits, DIY parts, deskmats, and other items are always available for purchase.

What connectors do I need?

That depends on what you are plugging your cable into. Below are some general rules of thumb, and images of some of the most common types of connectors we offer.



USB Type-A

USB Type-A connectors typically plug into the back or front panels of your computer (or outlet adapter).



Mini-USB is a popular connector type that plugs into most mechanical keyboards, digital cameras, external hard drives, and USB hubs.



Micro-USB is a popular connector type that plugs into small devices like cellphones, tablets, and other portable devices.


USB Type-B

USB Type-B connectors are square shaped, and are found on printers, scanners, and other peripheral devices.


USB Type-C

USB Type-C connectors are reversible connectors that are popular on many newer smart phones and computers.

How long can a USB cable be?

We recommend keeping the total length of your cable under 16 feet. Anything longer than that, and the cable falls out of USB spec and risks losing its transmission power, which could cause it to under-perform or fail.

If you are using your USB cable to connect a keyboard that draws a larger amount of power (one with a lot of LEDs or RGB functionaity for example), the maximum operative length may be significantly shorter than 16 feet. In most cases, 10 feet or less is preferable.

Based on testing we've done with our cables, there are some high-powered keyboards that require even shorter cables—like HHKBs (8 feet) and Input Club’s K-Type or Massdrop’s CTRL (7 feet).

What do you make the cables out of?


The cable we use is a USB 2.0 spec 28AWG, four-core dual-shielded cable that has tinned copper conductors and a PVC jacket.


The cord we use is USA-made Type III nylon (or nylon/polyester) paracord.


The double-sleeving materials we offer are Techflex Flexo PET and MDPC-X sleeving.

What is double-sleeving?

Double-sleeving is a second layer of sleeving that covers the cord and adds an extra layer of durability, rigidity, and style.


What is the difference between Techflex and MDPC-X?

Both Techflex and MDPC-X are made out of the same type of material (woven plastic threads). The main difference is in the density of the weave. Techflex is a looser weave and will reveal more of the cord color underneath. MDPC-X is a tighter weave, and will cover 100% (more or less) of the cord underneath.

What’s up with coils?

Coils are a fun way to add a little extra style to your cable. While our coils have good memory and are made with care, they are primarily an aesthetic feature. Prolonged stretching or aggressive handling may weaken the coils and loosen their uniform appearance over time.

Unless specified otherwise, our coiled cables will have about 4" of straight cable on the device end (typically a Mini-USB, Micro-USB, or USB-C connector), then the coiled section, and then the remainder of the cable length on the host (USB-A) end.

Ordering note: When ordering coils, the length of coils you select will be built in to the overall length of the cable. For example, if you order a 4-foot cable with 6 inches of coils, the cable will not be 4’6” in overall length. It will be 4 feet long and include 6 inches of coils.



Will my cable work when it arrives?

Of course, yes! We double-check every cable before we ship it to make sure it is working properly. If for any reason you receive a cable that does not work out of the box, let us know right away and we will send you one that does.

Do you ship internationally?

You bet! We’ll ship anywhere. When placing an order, you should be presented with the appropriate shipping options for your country. If you’d like to get a custom shipping quote or have shipping questions, contact us and we’ll get you the information you need. Be aware, international orders may incur additional import fees (consult your local postal delivery service for more information) not covered by your quoted shipping rate.

What is your return policy?

We offer returns to any Zap customer who isn’t completely satisfied with their cable. You ordered from us, and that means a lot. If you’re not totally satisfied with your cable, please let us know. We’ll do everything we can to address the problem and get you a cable you are totally satisfied with. Unfortunately, we do not accept returns on DIY Kits.

If you do want to return your item(s), we’ll be happy to help you out. Use the form on our Contact page or shoot an email to hello@zapcables.com with your order number and the nature of your dissatisfaction, and we will address your request posthaste!
