6Ft NEMA 5-15P to C19 UPS Power Cord
Best for UPS units and PDUs that require a sturdy C19 inlet connection. This 6-foot, 14 AWG cord is rated for 16A/20A at 125V and uses a wear-resistant black PVC jacket. It carries UL and cUL safety certification, making it suitable for critical hardware that demands reliable, high-current power transmission. Choose this if your equipment demands a heavy-duty, high-current link with a standard NEMA 5-15P plug on one end and IEC C19 on the other.
Limitations: The 6 ft length may be less flexible in tight rack spaces; consider shorter or longer options if your cable routing is constrained.
Standard 5ft 3-Prong Cable
This versatile 5-foot cord with a 3-prong plug supports common electronics including monitors, PCs, printers, and TVs. It features a fully molded design for maximum durability and long life. Best for budget-minded buyers who need a reliable, universal power cord compatible with devices that accept a standard 3-pin connection.
Limitations: Not specifically designed for high-current 20A equipment or IEC C19 inlets; verify device inlet compatibility before purchase.
Cablelera NEMA 5-15P to IEC 320 C19 Power Cord Extension
Best for IEC C19 inlet equipment requiring a dedicated extension within 125V/15A limits. This 6-foot extension is designed specifically for C19 connections (not C13 or 20A devices). It provides a safe, reliable extension option when the device is already anchored but needs a longer reach to the power source.
Limitation: Not compatible with C13 inlet devices or high-current equipment; ensure the connected device does not exceed 15A.
Power Cable UPS Server Y Splitter
Best for PDUs and UPS setups needing dual C13 outputs from a single C14 inlet. The 34 cm Y-splitter (two female C13 connectors) keeps cabling tidy and enables powering two devices from one UPS/PDU outlet. Choose this when you want to reduce cable clutter in tight rack or desk spaces.
Limitation: Not intended to power high-power devices from a single outlet; check total current draw to stay within 10A capacity.
Power Cord 5ft 10A 125V 18AWG
Best for standard electronics and smaller devices that require a reliable 5-foot 125V connection. The 18 AWG conductor and 10A rating, coupled with ETL listing, provide a safe option for TVs, monitors, printers, and similar equipment. It is compatible with devices using a NEMA 5-15P to C13 plug configuration.
Limitation: May not be suitable for high-current servers or PDUs that exceed 10A; verify device power needs before use.
Buying Guide
What inlet and outlet configurations do you need?
Identify whether your equipment uses NEMA 5-15P, IEC C13, or IEC C19 connectors. For UPS and PDU setups, IEC C19 inlets are common on the device side, while the supply cord usually ends in a NEMA 5-15P plug.
What length is appropriate?
Measure distance from the power strip or UPS to the equipment to avoid excess slack, which can create clutter or trip hazards. Shorter cords reduce resistance in high-current paths; longer cords provide flexibility in layout but may increase cable mess.
What current rating is required?
Most consumer electronics use 10A to 15A. UPS and PDUs may require 15A or 20A connections. Do not exceed the rated current of the cord or device inlet and ensure compatibility with the equipment.
Is flexibility or durability more important?
Fully molded cords offer durability and kink resistance, which is useful in busy office environments. Heavier-duty jackets (PVC or rubber) and copper conductors enhance longevity in racks and industrial settings.
Safety and compliance considerations
Look for UL/cUL listings and ETL labeling for safety assurance. If your setup sits in professional IT or data-center environments, cords designed for high-reliability operations are preferred.
Quick–start comparison by scenario
- UPS and PDU heavy-duty needs: 6 ft NEMA 5-15P to C19 (DEALTUS) — best for high-current C19 equipment.
- General electronics and monitors: Standard 5 ft 3-prong (no brand) — best value and universal compatibility.
- C19 inlet equipment only: Cablelera NEMA 5-15P to IEC 320 C19 (6 ft) — best for dedicated C19 devices.
- PDUs with dual device power: UPS Server Y Splitter (34 cm) — best for tidy dual-device connections.
- Budget, ETL-listed option for mixed devices: Power Cord 5 ft 10A 125V (Vockjour) — best for general use.
FAQ
- What is the difference between C13 and C19 connectors? C13 is a female connector commonly used on PDUs and older power strips; C19 is a higher-current inlet typically used on enterprise equipment and UPS devices. The cord must match the inlet on the device.
- Can I use a 15A cord with a 20A UPS? If the UPS inlet and device are rated for 20A and the cord is 15A, it may limit performance. Use a cord rated for at least as much current as the equipment requires.
- Are these cords tested for safety? All listed cords shown are described with safety certifications (UL, cUL, ETL listed) and appropriate conductor material.
- Do longer cables affect power delivery? In typical household and office use, length mainly affects physical routing; electrical resistance grows slightly with longer runs, but within standard lengths the impact is minimal for common loads.
- What should I consider when choosing a Y-splitter? Ensure the splitter’s total current draw does not exceed the power source and the connected devices’ sum does not exceed the cord’s amperage rating.
- Are these cords compatible with all brands? Most cords use standard IEC and NEMA configurations and fit a wide range of brands and devices with compatible inlets.
