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 only offering cables for sale in readymade batches. We are no longer accepting orders for one-off custom cables. We will release new readymade batches for sale on a weekly-ish basis, and they will be available for immediate shipment (generally a day or two). Once the inventory from any given batch has been sold through, it will be marked as "Out of Stock." You can get updates on upcoming batches in our Discord server, through our email newsletter, or via our Instagram page.
Please keep in mind that other products like DIY kits, DIY parts, deskmats, and other items are always available for purchase.
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 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 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 connectors are square shaped, and are found on printers, scanners, and other peripheral devices.
USB Type-C connectors are reversible connectors that are popular on many newer smart phones and computers.
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.
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.
Please note: Since MDPC-X will cover up the cord underneath it, we recommend selecting a matching color for your cord. If you need any advice on what cord color matches a specific MDPC-X color best, feel free to contact us and we can advise.
Top: Bare cord | Middle: Cord with Techflex | Bottom: Cord with MDPC-X
Can I purchase MDPC-X sleeving by itself?
Unfortunately, we cannot sell MDPC-X sleeving a la carte. MDPC-X is a German company that has exclusive re-seller partnerships with specific vendors in individual countries, and unfortunately we are not the exclusive partner for USA. We are allowed to sell it as part of a product or kit, but not on its own.
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 cables with coils, the length of the coils 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 you sleeve or coil the DIY Kits for me?
Sorry, but no. We will not pre-sleeve or pre-coil any of the DIY Kits. Don't be afraid to give it a shot yourself! It's not terribly difficult, and if you get stuck there are a lot of people in our Discord server who can give you tips (including us).
What is the difference between a 4-pin and a 5-pin detachable connector?
The only real difference is the additional pin. Otherwise, the 4-pin and 5-pin detachable connectors are the same shape, size, and fit. We offer the 5-pin connectors by default, but we stock 4-pin connectors as well for legacy users who have pre-existing 4-pin connectors on their cables and want new cable pieces to match.
We attach the wires of our detachable connectors as described and shown in the image below, and recommend our DIY friends do the same. The pins of the detachable connectors are physically numbered, and correlate to the way the pins are assigned to USB connectors according to the USB spec:
1: VBUS (Red)
2: D- (White)
3: D+ (Green)
4: Ground (Black)
Please be advised that not all custom cable makers wire their detachable connectors the same. Mixing and matching detachable cable halves from different vendors without confirming they are compatible may result in damage to your PCB/device.
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.
Can you declare a lower value on my package?
Unfortunately, no. For international orders, customs laws mandate that we declare the actual value of goods sold.
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 email@example.com with your order number and the nature of your dissatisfaction, and we will address your request posthaste!
