Car Chargers That Fast Charge Two Phones at Once
The Anker PowerDrive III Duo is the strongest overall pick, delivering 36 watts of USB-C Power Delivery alongside a second port for simultaneous fast charging. Families with multiple devices should consider the Aukey CC-Y3 instead for its four ports, while anyone with an older phone will do fine with the budget-friendly Nekteck 45W PD charger.
The Anker PowerDrive III Duo leads this list because its 36-watt USB-C Power Delivery port charges modern phones quickly while a second port handles a passenger’s device at the same time. It has only two ports total, which can feel limiting on a family road trip. Drivers who need to charge more devices at once should look at the four-port Aukey CC-Y3.
We compared published wattage, port count, charging protocol support and physical footprint across each charger rather than running our own charging speed tests.
What we recommend

Anker PowerDrive III Duo
A 36-watt USB-C Power Delivery port charges supported phones significantly faster than standard USB-A, while a second USB-A port covers a passenger’s older device. Anker’s PowerIQ technology detects connected devices and adjusts output automatically. A compact aluminum casing dissipates heat better than plastic-only competitors.
Pros
- USB-C Power Delivery charges supported phones quickly
- Aluminum housing manages heat better than plastic chargers
- PowerIQ automatically adjusts output per device
Cons
- Only two total ports limits use on crowded road trips
- USB-C cable not included with the charger
Aukey CC-Y3
Four total ports, including one USB-C Power Delivery port, let an entire car of passengers charge devices simultaneously. Combined output stays high enough that charging speed does not collapse when all ports are active at once. A low-profile design keeps it from blocking other items in a crowded 12-volt outlet area.
Pros
- Four ports support an entire car of passengers at once
- High combined wattage avoids slow charging under full load
- Low-profile design fits tight outlet areas
Cons
- Larger footprint than single or dual-port chargers
- Individual port speed is lower than dedicated single-port fast chargers

Belkin BoostCharge Dual USB-C Car Charger
Two USB-C Power Delivery ports both support fast charging simultaneously, unlike chargers that pair one fast port with a slower USB-A port. Combined 30-watt output splits intelligently between two connected devices. Belkin’s compact build fits flush in most vehicle outlets without protruding far.
Pros
- Both ports support fast charging rather than just one
- Compact design sits nearly flush in the outlet
- Intelligent power splitting adapts to connected devices
Cons
- No USB-A port for older cables without adapters
- Combined wattage splits lower per port than single-port chargers

Scosche reVOLT USB-C PD Car Charger
A single USB-C Power Delivery port delivers up to 20 watts in one of the smallest car charger bodies available. Its minimal size barely extends past the outlet, useful in vehicles with a shallow 12-volt socket. The single port tradeoff means only one device charges at a time.
Pros
- One of the smallest car chargers available
- Fast charging speed for a single connected device
- Low profile avoids blocking nearby controls or cupholders
Cons
- Only one port limits it to a single device at a time
- Lower total wattage than multi-port competitors

Nekteck 45W PD Dual Port Car Charger
A 45-watt USB-C Power Delivery port plus a USB-A port cover both newer and older devices without the premium pricing of some name-brand chargers. Combined output stays high enough to fast charge a phone and tablet together. Build materials feel slightly less refined than Anker or Belkin equivalents.
Pros
- High combined wattage for its price point
- Covers both USB-C and older USB-A devices
- Compact enough for most vehicle outlets
Cons
- Plastic housing feels less premium than aluminum competitors
- Shorter warranty coverage than higher priced brands
RAVPower RP-VC006
Dual USB-A ports with RAVPower’s iSmart technology detect whether a connected device is an iPhone or Android phone and adjust charging voltage accordingly. This avoids the slower charging some generic chargers deliver to one device type over the other. It lacks a USB-C port, which newer phones increasingly require for fastest charging.
Pros
- Adaptive charging detects device type automatically
- Works well for mixed iPhone and Android households
- Compact, unobtrusive design
Cons
- No USB-C port limits fast charging on newer phones
- Lower total wattage than USB-C PD competitors

Anker 313 Car Charger
A single USB-A port in an unusually small housing barely protrudes from the outlet, useful in cars with limited clearance around the 12-volt socket. Output tops out at 12 watts, enough for standard phone charging but not for fast-charging newer devices. Its simplicity suits drivers who only need occasional backup charging.
Pros
- Extremely small footprint fits tight outlet clearance
- Simple, reliable charging for everyday needs
- Affordable price point for occasional use
Cons
- No fast charging support for newer phones
- Single port limits use to one device at a time

How to pick the right one
What wattage actually means for charging speed Total output wattage determines how fast a connected device can charge, but only up to the limit the device itself supports. A 36-watt USB-C Power Delivery port, like the one on the Anker PowerDrive III Duo, charges a compatible phone meaningfully faster than a 12-watt USB-A port. Older phones without fast charging support will not charge faster just because the charger offers more wattage.
USB-C versus USB-A for modern phones Most current phones use USB-C and support Power Delivery fast charging, which chargers like the Belkin BoostCharge Dual USB-C and Scosche reVOLT are built around. USB-A ports still matter for older phones, accessories and some dash cams that have not switched to USB-C. A charger with one of each port type, such as the Nekteck 45W PD, covers both situations in one device.
Single port versus multi-port chargers A single-port charger like the Scosche reVOLT delivers its full wattage to one device, which can mean faster charging than splitting power across multiple ports. Families or rideshare drivers who need to charge several devices at once should prioritize a four-port option like the Aukey CC-Y3 instead, accepting a lower per-port speed in exchange for covering more devices.
Fit and physical size considerations Some vehicles have a shallow or recessed 12-volt outlet that only accommodates compact chargers like the Anker 313 or Scosche reVOLT. Larger multi-port chargers, including the Aukey CC-Y3, extend further and may interfere with nearby cupholders or controls in tighter interiors. Drivers should check their outlet’s surrounding clearance before choosing a bulkier multi-port design.
Frequently asked questions
What is USB-C Power Delivery?
It is a fast charging standard that lets compatible chargers and devices negotiate higher power levels than standard USB, used in chargers like the Anker PowerDrive III Duo and Belkin BoostCharge Dual USB-C.
Can a car charger charge a tablet as fast as a wall charger?
A high-wattage USB-C PD car charger, like the Nekteck 45W PD, can approach wall charger speeds for many tablets, though some larger tablets may still charge slower in a vehicle.
Do I need a USB-C or USB-A car charger?
Most phones made recently use USB-C, but a charger with one of each port, such as the Nekteck 45W PD Dual Port, covers both newer and older devices without needing two separate chargers.
How many ports does a family car charger need?
A four-port charger like the Aukey CC-Y3 suits families or rideshare drivers who regularly charge several devices at once. Two ports are usually enough for a driver and one passenger.
Does charging multiple devices at once slow down charging speed?
It can, since total wattage is shared across active ports. High combined output chargers like the Aukey CC-Y3 are built to minimize that slowdown compared to lower wattage multi-port units.
What does iSmart or adaptive charging mean?
It refers to technology, like RAVPower’s iSmart in the RP-VC006, that detects whether a connected device is an iPhone or Android phone and adjusts voltage for optimal charging speed.
Will a 45 watt car charger damage an older phone?
No. Modern charging standards include safeguards that prevent overcharging, so a higher wattage charger like the Nekteck 45W PD will simply charge an older phone at its own supported speed.
Why do some car chargers stick out further than others?
Internal components for higher wattage or multiple ports require more space, which is why compact single-port chargers like the Scosche reVOLT sit closer to the outlet than four-port designs.
Our pick
The Anker PowerDrive III Duo suits most drivers who want fast charging for themselves and a passenger without extra bulk. Families or rideshare drivers who regularly charge three or four devices at once should pick the Aukey CC-Y3 instead for its extra ports. Drivers with an older phone that does not support fast charging can save money with the Nekteck 45W PD Dual Port without losing meaningful charging speed.
