Charging two devices in your car can become frustrating when one port is slow or your adapter cannot provide enough power. The LISEN 90W USB C Car Charger, model 2E790, addresses that problem with two USB-C ports rated for up to 45W each and a listed 90W maximum total output. Its compact metal body is another advantage when you do not want a bulky adapter sticking out of the dashboard. The main tradeoff is that both outputs are USB-C and each port tops out at 45W, so buyers needing USB-A or higher single-port laptop power should compare other options.
Quick Verdict
Rating: 8.7/10, Recommended with caveats
Best For: Drivers who want two USB-C fast-charging ports in a compact 12V car adapter.
Bottom Line: The dual 45W ports, 90W listed total output, metal construction, and compact size make this a strong choice for phones, tablets, and some USB-C laptops. Skip it if you need a USB-A port or more than 45W from one charging port.

- Power Delivery 3.0 support makes the charger suitable for compatible iPhones, Galaxy phones, tablets, and other PD devices.
- The approximately 2.1 × 0.9-inch body sits relatively low in many vehicle accessory sockets and helps reduce console clutter.
- The metal-alloy shell provides a sturdier exterior and helps move heat away from internal charging components.
- The current listing identifies model 2E790 and includes one charger, so do not assume charging cables are included with this ASIN.
What Is the LISEN 90W USB C Car Charger?
The LISEN 2E790 is a compact cigarette-lighter or vehicle accessory-socket charger designed to convert your car’s 12V DC power into USB-C charging power. Instead of combining one USB-A port with one USB-C port, this model gives you two USB-C outputs.
Each USB-C port is rated for up to 45W, and LISEN lists a maximum total output of 90W. That layout is useful when you and a passenger both use modern USB-C devices or when you want to power a phone and tablet at the same time.
The charger supports Power Delivery 3.0, and the current Amazon title also identifies QC 3.0 fast-charging support. Actual charging wattage still depends on your device, cable, battery level, temperature, and the charging protocol the device accepts.
Who Should Buy It?
Best For
- Drivers with two USB-C phones, tablets, or other PD-compatible devices.
- You if you want a compact adapter that does not protrude far from the vehicle outlet.
- Families or road-trip passengers who often need to charge two devices together.
Skip If
- You still depend on USB-A cables and do not want to replace them.
- Your laptop needs substantially more than 45W from a single port for normal charging under load.
- You need three or more charging ports from one vehicle adapter.
Before You Buy: The 90W figure is the listed maximum total output across both USB-C ports. Each individual port is rated for up to 45W, so this is not a 90W single-port laptop charger. This ASIN also lists one charger as the included component, so plan to use your own compatible USB-C cable.
Fast Charging Capabilities
The main reason to choose this model is its dual 45W USB-C arrangement. When two compatible devices are connected, the charger is designed to provide up to 45W from each port rather than forcing both devices to share a much lower combined output.
LISEN’s current Amazon listing states that PD 3.0 charging can bring a compatible iPhone 18 Pro from 0% to about 83% in roughly 30 minutes under the seller’s test conditions. Treat that as a manufacturer performance claim rather than a guaranteed result. Your real charging rate can change as the phone heats up, approaches a high battery percentage, or negotiates a lower wattage.
A 45W ceiling per port is more than many phones can use and is enough for numerous tablets and lower-power USB-C notebooks. Higher-performance laptops may accept 45W but charge slowly during use, and some may require a higher-wattage adapter to maintain battery level under heavy workloads.
Design and Build Quality
The body measures about 2.1 inches long and 0.9 inches wide, making it small enough to sit close to the edge of many 12V sockets. That matters in center consoles where a large charger can interfere with a cover, cup holder, or nearby controls.
LISEN uses an all-metal alloy shell rather than an entirely plastic exterior. Metal can help transfer heat away from the charger’s electronics and also gives the plug a more solid feel. Some warmth during high-output charging is normal, but excessive heat, burning odor, smoke, or repeated power interruptions are reasons to unplug it and stop using it.
The charger also has a charging indicator so you can confirm that your vehicle socket is supplying power. Keep in mind that some vehicles turn the accessory outlet off with the ignition, while others leave it powered after the engine stops.
Fit and Compatibility
The Amazon listing identifies the charger for a 12V DC vehicle accessory outlet. Before buying, check that your car’s socket is the standard cigarette-lighter-style outlet and that there is enough clearance around it for the charger’s body and your USB-C cable connectors.
Compatible devices listed for this product include recent iPhone and Samsung Galaxy models. PD-compatible tablets and some USB-C laptops can also use the charger. For an older iPhone with a Lightning connector, you need a suitable USB-C-to-Lightning cable. The charging port on the adapter is USB-C, not Lightning.
Fast charging also depends on the cable. A damaged, low-quality, or under-rated cable can reduce charging speed even when the charger itself supports higher wattage.
Pro Tip: Use a USB-C cable rated for the power your device needs. If charging seems unusually slow, test one device at a time with a known-good PD cable before assuming the charger is faulty.
Compatibility and Safety
The seller lists UL, CE, FCC, and RoHS certifications for this model and describes an intelligent power-management chip. Amazon also lists short-circuit protection and automatic-off functionality among its special features.
LISEN states that the construction uses V-0-grade flame-retardant PC material in addition to the metal exterior. These protections are useful, but they do not replace basic vehicle-electronics safety. Keep the charger dry, make sure the accessory socket is free of debris, and do not use the charger after significant physical damage.
If the adapter becomes excessively hot, repeatedly disconnects, produces a burning smell, or shows visible damage, unplug it. Do not cover the charger while it is working because high-output charging naturally creates some heat.
Setup Tips and Common Mistakes to Avoid
- Insert it fully. A partially seated charger may lose contact when the vehicle moves over bumps.
- Check for the power indicator. If it stays off, verify that your vehicle’s accessory socket is active.
- Use a capable cable. A USB-C port cannot deliver its full potential through a cable that does not support the required charging standard.
- Confirm your device’s input limit. A device that accepts 20W will not suddenly charge at 45W just because the charger can provide 45W.
- Keep the socket clean. Dirt or loose debris can interfere with a stable electrical connection.
How It Performs in Real Use
For Daily Commuting
For a single phone, the charger’s 45W-per-port ceiling gives you plenty of headroom for many modern fast-charging phones. Its low-profile size is especially useful if you leave the charger installed between trips.
For Two-Person Road Trips
The dual USB-C layout is most useful when two people need power at once. Instead of swapping one fast port between devices, you can connect two compatible USB-C cables and charge both devices simultaneously.
For a Phone and Tablet
A phone plus an iPad or other USB-C tablet is a practical pairing because both ports can independently provide up to 45W. Your device determines how much of that available power it actually draws.
For USB-C Laptops
The charger can be useful as an emergency or travel power source for laptops that support USB-C PD and can operate from a 45W supply. It is less suitable for performance laptops that normally use 65W, 100W, or higher adapters, especially while demanding applications are running.
Everyday User Benefits
The strongest benefit is simple: you do not have to choose which of two modern USB-C devices gets the fast port. Each connection can deliver up to 45W, while the small metal housing takes up little dashboard space.
The USB-C-only design is also cleaner for households that have already moved away from USB-A. On the other hand, that same design creates a compatibility inconvenience if your existing car cables all end in USB-A plugs.
Pros and Cons
Pros
- Two USB-C ports rated for up to 45W each.
- Up to 90W maximum listed total output.
- Compact 2.1 × 0.9-inch body reduces dashboard clutter.
- Metal-alloy shell helps with durability and heat transfer.
- PD 3.0 support and listed safety protections cover common modern charging needs.
Cons
- No USB-A port for older car charging cables.
- Maximum output is 45W per port, which can be limiting for higher-power laptops.
- The current ASIN lists the charger itself as the included component, so you should not assume cables are supplied.
Is It Worth the Price?
The LISEN 2E790 is best viewed as a value-focused option for drivers who specifically want two reasonably powerful USB-C ports without a large adapter. Its feature set is more useful than a basic single-port charger when you regularly travel with another person or carry both a phone and tablet.
You get the most value if your devices can benefit from USB-C PD but do not require more than 45W individually. If you need a 65W or 100W single-port output for a demanding laptop, paying for a higher-power car charger may make more sense.
How It Compares to Alternatives
If you need more total power and three charging ports, the UGREEN 130W 2C1A car charger is worth comparing because it combines two USB-C outputs with a USB-A port. It makes more sense for users carrying several devices or hardware with higher charging requirements.
The Spigen ArcStation PC2000 is another dual-USB-C option, with a lower 65W total output. The LISEN makes the most sense when you specifically want two ports capable of up to 45W each and prefer its compact metal design.
Frequently Asked Questions
Does the LISEN charger really provide 90W from one port?
No. The product is listed for up to 90W total across two USB-C ports. Each individual USB-C port is rated for a maximum of 45W.
Is it compatible with older iPhones?
Many older Lightning-equipped iPhones can charge from a USB-C power source when you use an appropriate USB-C-to-Lightning cable. Charging speed depends on the specific iPhone model and the cable you use.
Can it charge a USB-C laptop?
It can charge compatible USB-C PD laptops that accept power from a 45W source. A laptop designed around 65W, 100W, or higher adapters may charge slowly or lose battery during demanding use.
Does this ASIN include charging cables?
The current Amazon listing for ASIN B0CGN8Z6J7 identifies the included component as one LISEN 90W car charger adapter. Use a suitable USB-C cable for your device unless the seller’s current purchase option specifically states otherwise.
What type of vehicle socket does it use?
The verified listing describes a 12V DC cigarette-lighter or vehicle accessory-socket charger. Check your vehicle manual if you are unsure about the voltage or type of accessory outlet in your car.
Is it normal for the metal body to become warm?
Some warmth can occur during high-power charging because power conversion creates heat and the metal shell helps dissipate it. Disconnect the charger if it becomes excessively hot, smells burnt, smokes, or behaves abnormally.
What safety certifications are listed for the charger?
LISEN’s listing states that the charger has passed UL, CE, FCC, and RoHS certifications. The product also lists short-circuit protection and intelligent power-management features.
Does the LISEN 90W car charger have a warranty?
