Look at the power brick of a laptop, a game console, a small printer, a Bluetooth speaker, or a slim TV and there is a good chance the cord plugs in with a small, figure-8 shaped connector. That connector is IEC C7, and the other end of the cord is almost always a two-prong US wall plug, known as NEMA 1-15P. It is one of the most common power cords in everyday electronics, and one of the easiest to lose, since it often gets packed away with a move, left behind in a hotel room, or chewed through by a pet.

Replacing it looks simple, but there is one detail that trips people up: polarization. A non-polarized C7 cord has a symmetrical connector that fits either way around, while a polarized cord has one flat or squared-off side and only fits in one direction. Most laptop bricks and consoles accept the non-polarized >

1. SF Cable — NEMA 1-15 Power Cords

SF Cable's NEMA 1-15 category is built around exactly this cord, and it covers both polarized and non-polarized versions in the same place, so there is no guessing about which one a device needs. The cords are 18 AWG and fully molded, and they come in a wide spread of lengths, from a compact one-foot cord for tight desk setups up to 20 feet for equipment that sits far from the wall. White versions are available alongside standard black, and low-profile angled options handle spots where a straight plug would stick out too far.

SF Cable also backs its cables with a lifetime warranty and free technical support, which is a real advantage when the question is not just which cord to buy but whether it will fit a particular device. For anyone replacing a lost laptop or console cord, or stocking a classroom or office with spares, it is the most complete single stop on this list.

2. Infinite Cables — AC Power Cords

Infinite Cables' AC power cords category includes NEMA 1-15P to C7 cords in both polarized and non-polarized versions, built with 18 AWG bare copper conductors and SPT-2 jackets rated for 7 amps at 125 volts. Lengths run from a short 1.5 feet up to 25 feet, which is longer than most competitors offer for this cord.

Each assembly is continuity tested and high-voltage tested before shipping, and the cables carry c(UL)us approval, which makes this a reasonable pick for buyers who care about documented testing. The category also includes down-angle versions and simple 1-15P to C7 adapters for converting an existing cable.

3. Monoprice — Laptop AC Power Cords

Monoprice groups this cord under Laptop AC Power Cords, and the selection is straightforward: non-polarized 18 AWG cords rated for 7 amps in lengths of 1, 3, 6, 10, and 15 feet, plus a polarized 10-amp version for equipment that needs it. The non-polarized cord is a long-running best seller with hundreds of customer ratings, which is useful social proof for a part that is easy to get wrong.

Monoprice is a good choice for buyers who are already ordering other cables and accessories and want to keep everything in one cart, and its pricing on short and mid-length cords is competitive.

4. Cable Leader — 1-15P to C7 (2-Prong Non-Polarized)

Cable Leader organizes its notebook power cords by connector type, so the 1-15P to C7 non-polarized category lands exactly on the cord this article is about. The cords are 18 AWG SPT-2, rated 7 amps at 125 volts, and UL, cUL, and CSA listed. The same section links to polarized versions and to low-profile and right-angle options.

The ultra-low-profile cords are worth a closer look for anyone plugging into an outlet behind a couch, a TV mount, or a crowded power strip, where a standard straight plug sticks out too far. Cable Leader also offers an unusual range of in-between lengths such as 8 feet.

5. CableWholesale — Power Cords

CableWholesale's power cord category carries NEMA 1-15P to C7 cords in both non-polarized and polarized >

What sets CableWholesale apart is its bulk and custom ordering. Volume pricing tiers are listed right on the product pages, and a custom length request is available for installers and facilities that need a specific size, which makes this a practical option for outfitting an entire office or classroom.

How to Choose the Right NEMA 1-15P to C7 Cord

A few quick checks make the decision easy before an order goes in:

● Polarized or non-polarized: Look at the power port on the device. If it is symmetrical like a figure 8, a non-polarized cord is the right fit. If one side is flat or squared off, buy the polarized version, since a non-polarized plug will not seat properly.

● Amperage: Standard C7 cords are rated for 7 amps, which is plenty for laptops, consoles, and small electronics. Check the label on the device's power supply to make sure it draws less than that.

● Length: Measure from the outlet to the device, then add a little slack. A cord that is too tight puts strain on the connector, while an overly long cord adds clutter.

Final Thoughts

A NEMA 1-15P to C7 cord is a small, inexpensive part, but a wrong one can mean a device that will not charge or a plug that will not seat. The five sources above cover the range of what is available, from SF Cable's mix of polarized, non-polarized, and low-profile options with lifetime support to Infinite Cables' longer lengths, Monoprice's easy one-cart ordering, Cable Leader's connector-specific layout, and CableWholesale's bulk and custom orders. Checking polarization first, then matching length and plug profile to the space, gets the right cord on the first try.
