Featuring plug-and-play design, it can be directly inserted into the original fuse slot for power access. No wire stripping or soldering is needed. It keeps the original wiring intact and will not void vehicle warranty. Even beginners can operate it easily, and the original circuit can be fully restored anytime.
Comes with an independent fuse slot, compatible with fuses from 1A to 30A for flexible matching according to device power. It does not affect the protective function of the original vehicle fuse, realizing dual protection by both original and additional fuses. It effectively prevents circuit burnout and battery drain caused by overload, short circuit and reverse connection.
Available in three sizes: standard, medium and mini fuse taps. Compatible with fuse boxes of most passenger vehicles including sedans, SUVs, MPVs and some commercial vehicles, delivering excellent universal adaptability.
The cable adopts high-purity tinned copper or solid copper conductor, featuring outstanding conductivity, low voltage drop and low heat generation to carry rated current stably. The outer sheath is made of high-temperature resistant and flame-retardant PVC/TPE material, which resists aging, extreme cold and heat. It works reliably in engine bays and cabins with drastic temperature changes, and is not prone to cracking or deformation after long-term use.
The housing is made of high-strength flame-retardant ABS, anti-drop and anti-corrosion. The transparent or semi-transparent fuse cover allows direct visual inspection of fuse status. Fuse replacement can be done without disassembly for easy maintenance.
Some models are equipped with anti-reverse structure to avoid device damage due to incorrect positive/negative connection. The cable ends are pre-terminated with standard lugs or bare wires, which can be quickly connected via soldering or terminals to fit various wiring scenarios.
The fuse tap has a small footprint. It takes up no extra space after installation and does not hinder closing the fuse box cover. It can be hidden inside the fuse box for neat wiring with no exposed parts.
| Comparison Item | This Fuse Tap | Traditional Wire Stripping Power Tap | Inferior Ordinary Fuse Tap |
| Impact on Circuit | Damage-free installation, no circuit alteration, warranty remains valid | Damages original wiring, likely to cause poor contact and short circuit, voids vehicle warranty | Minor modification required for some models, no standard safety protection |
| Safety Protection | Dual fuse + flame-retardant material, automatic power cut under overload/short circuit | No extra protection. Overload may burn wires and even lead to vehicle fire | Fuse slot tends to overheat and burn out; poor cable conductivity and short service life |
| Installation Difficulty | Tool-free plug-in installation, easy for beginners | Requires wire stripping and soldering, professional tools and skills needed | No standard installation guide, poor compatibility and easy misinstallation |
| Durability | High-temperature & flame-retardant materials, stable performance in harsh automotive environments | Cable insulation ages and cracks easily; connection points oxidize with high failure rate | Fragile housing and breakable cables, short service life and frequent faults |
| Maintenance Convenience | Fuse replaceable without disassembly, real-time status visible | Wiring needs to be disassembled for inspection, difficult and inefficient troubleshooting | No transparent cover, hard to judge faults and inconvenient maintenance |
Draw constant power or ACC power for dash cams, streaming rearview mirrors, car navigation, GPS trackers, car air purifiers, car chargers and more. It supports power-off cut-off or continuous power supply to avoid battery drain.
Damage-free power tapping for LED daytime running lights, ambient lights, welcome lights, fog lights and other lighting equipment. Matched with proper fuses to ensure safe and stable operation of lighting circuits.
Front-end fuse protection for high-power devices such as emergency start aids, car inverters, car refrigerators and air pumps. Equips independent protection for connected devices without interfering with original vehicle circuits.
Temporary or long-term power tapping and testing during circuit refitting and upgrading. Provides a safe power interface for circuit detection and device commissioning, and avoids risks from direct contact with original wiring.

Q1: Will this fuse tap affect vehicle warranty?
A: No. It adopts damage-free plug-in design with no wire stripping, soldering or circuit damage. It can be removed to fully restore the original state, so the vehicle warranty will not be affected.
Q2: How to select the right fuse tap and fuse current?
A: 1. Check the fuse type of your original fuse box and choose standard/medium/mini fuse tap accordingly. 2. Calculate current by formula: Current = Power ÷ Voltage (12V/24V for vehicles). Select a fuse with rating slightly higher than the device rated current. For example, a 10W dash cam draws about 0.8A, so a 5A fuse is recommended. Choose corresponding specifications for high-power devices.
Q3: Can one fuse tap supply power to multiple devices?
A: It is not recommended to connect multiple high-power devices to a single tap. One tap is suggested for one device. If multiple devices are needed, use separate fuse taps on different slots, or select taps with larger wire gauge and higher current rating along with proper fuses to prevent overheating caused by overload.
Q4: Why is the device not powered after installation?
A: There are three common reasons: 1. The fuse is blown, replace with a new fuse of the same rating. 2. The fuse tap is inserted reversely or loosely, re-install and fix it firmly. 3. Wrong wiring of the device, check positive/negative connection or possible device failure.
Q5: Is it compatible with 24V trucks?
A: Yes. It works with 12V/24V DC automotive circuits. Just select a proper fuse according to device power. For trucks, models with larger wire gauge are recommended to meet higher current demand.
Q6: Can customized specifications be made?
A: Yes. We offer customized products based on your fuse box size, device current demand, cable length and terminal type. For bulk orders, logo printing and customized packaging are also available.
