What the Anker Nano wireless charger does and what it doesn't

The Anker Nano Wireless Car Charger is a dashboard or windshield-mounted pad that charges your phone wirelessly while you drive. It uses the same inductive charging technology as wireless charging pads at home — you place your phone on it, and power transfers through the air gap without a cable. The charger plugs into your car's 12-volt power outlet (the cigarette lighter socket) or hardwires to your vehicle's electrical system.

What it does not do: it does not charge your electric vehicle. It charges only your phone or other small devices that support wireless charging. If you own an EV, this is a convenience accessory for your phone, not a charging solution for the car itself. Your EV charges through a dedicated Level 1, Level 2, or DC fast charger at home, work, or a public station — a completely separate system.

The Nano model is Anker's compact version, designed to take up minimal dashboard space while holding phones up to about 6.5 inches wide. It generates enough heat during charging that Anker includes a small cooling fan to keep your phone from overheating in direct sunlight or during long drives.

Key Takeaways

  • The Anker Nano charges your phone wirelessly through inductive technology; it does not charge your electric vehicle.
  • It draws power from your car's 12-volt outlet or hardwired connection and works with any phone that supports wireless charging, regardless of brand.
  • The built-in cooling fan prevents your phone from overheating during charging, which matters in hot climates or direct sunlight.
  • Thick phone cases or metal attachments can block the wireless signal, so you may need to remove them or use a thinner case.
  • Installation takes 10 to 30 minutes depending on whether you use the 12-volt outlet (easiest) or hardwire it (more permanent but requires basic electrical work).

How wireless charging works in a moving vehicle

Wireless charging relies on electromagnetic induction. The charger contains a coil that generates a magnetic field; your phone contains a matching coil that picks up that field and converts it to electrical current. This happens across a small air gap — typically a few millimeters — which is why the phone must sit flat on the pad and stay in contact.

In a car, the main challenge is vibration and movement. Every bump, turn, and acceleration can shift your phone slightly, breaking the alignment between the two coils. The Anker Nano addresses this with a non-slip rubber surface and a form-fitted cradle that keeps your phone centered. If your phone slides out of alignment, charging stops until it settles back into position — you will notice the charging light flicker or go dark.

The cooling fan is essential in a car because wireless charging generates more heat than wired charging. Your phone's battery and the charger coil both warm up, and a hot phone in a hot car can throttle its processor or stop charging altogether to protect itself. The fan pulls air across the charger and your phone, keeping both cooler and allowing charging to continue uninterrupted.

Power source: 12-volt outlet versus hardwiring

The Anker Nano ships with a cable that plugs into your car's 12-volt power outlet. This is the easiest installation — you plug it in, route the cable along your headliner or down the side of your dashboard, and you are done. No tools, no permanent changes to your car's wiring. The downside: the outlet is shared with other accessories (phone chargers, heated seat pads, dash cams), and drawing too much power from it can dim your headlights or drain your battery if the engine is off.

Hardwiring connects the charger directly to your car's fuse box, drawing power from a dedicated circuit. This is more permanent and does not compete with other 12-volt devices. It requires running a cable through your dashboard and connecting it to a fuse holder, which involves removing trim panels and working with your car's electrical system. If you are not comfortable with basic automotive electrical work, a car audio shop can do this in under an hour for a modest labor fee.

For most EV owners, the 12-volt outlet is sufficient. You are not running the charger for eight hours straight; you are charging your phone during a 30-minute to 2-hour drive. The outlet can handle that load without issue.

Compatibility: which phones actually charge wirelessly

Not every phone supports wireless charging. iPhones from the iPhone 8 onward (including all current models) have built-in wireless charging coils. Most flagship Android phones do as well — Samsung Galaxy S series, Google Pixel 6 and later, OnePlus flagships — but budget and mid-range Android phones often do not. Check your phone's specifications or manual to confirm it lists "wireless charging" or "Qi charging" as a feature.

Even if your phone supports wireless charging, thick cases and metal attachments block the signal. A rubber case under 3 millimeters thick usually works fine. A heavy leather case, a metal ring mount, or a magnetic car mount will prevent charging. You have two options: remove the case or attachment before placing your phone on the charger, or buy a thinner case specifically rated for wireless charging.

The Anker Nano works with any phone that supports the Qi wireless charging standard, which is the universal standard across all manufacturers. You do not need an Anker phone or any proprietary accessory.

Installation and mounting options

The Anker Nano comes with two mounting options: a dashboard suction cup and an air vent clip. The suction cup sticks to your windshield or dashboard and can be repositioned; the vent clip clamps onto your dashboard air vent and holds the charger at an angle. Choose based on your dashboard layout and how you want to view your phone while driving.

If you use the 12-volt outlet, plug the cable in, route it behind your dashboard trim or along the headliner to hide it, and find it with adhesive clips or cable ties. This takes 10 to 15 minutes. If you hardwire it, you will need to remove dashboard panels to access the fuse box, run the cable through the interior, and connect it to a fused power line. This takes 30 minutes to an hour depending on your car's design and your comfort level with electrical work.

Before you mount it, test the charger in your car with your phone to make sure the magnetic field reaches your phone's charging coil. Place your phone on the pad, watch for the charging indicator light, and confirm your phone's charging symbol appears on screen. If nothing happens, your phone may not support wireless charging, or your case is too thick.

Charging speed and real-world performance

The Anker Nano delivers 10 watts of wireless charging power, which is standard for car wireless chargers. This is slower than a wired car charger (which can deliver 18 to 30 watts) but faster than a standard wall outlet charger at home. In real terms: a fully drained phone battery will reach 50 percent charge in roughly 45 minutes to an hour of driving, depending on your phone model and how much power it is using while you drive.

Charging speed drops if your phone is actively in use — navigation, music streaming, or video calls all draw power that would otherwise go to the battery. On a long highway drive with minimal phone use, you will see faster charging. On a short city drive with heavy phone use, you might barely gain 20 percent charge.

The cooling fan runs continuously while the charger is powered on, even if your phone is not on the pad. This is normal and prevents the charger itself from overheating. The fan is quiet enough that most drivers do not notice it over road noise.

Durability and long-term reliability

The Anker Nano is built with a metal frame and rubber grips, designed to survive years of daily use in a car. The suction cup or vent clip will eventually wear out and may need replacement, but Anker sells replacement mounting hardware separately. The charging coil itself has no moving parts and should not degrade over time.

Heat is the main enemy of wireless chargers. If your car sits in direct sunlight for hours in a hot climate, the charger can overheat and shut itself down as a safety measure. Once it cools, it will resume charging. Parking in shade or using a sunshade reduces this risk. The cooling fan helps, but it cannot overcome extreme heat.

Anker backs the Nano with an 18-month warranty covering defects in materials and workmanship. If the charger stops working within that period and you did not damage it, Anker will replace it. Keep your receipt and register your product on Anker's website to set up the warranty.

Alternatives and when to choose something else

If your phone does not support wireless charging, a wired car charger is your only option. These plug into your 12-volt outlet or hardwire to your electrical system and deliver power through a USB cable. They are faster than wireless chargers and work with any phone, but they require a cable and take up more space.

If you want to charge multiple devices at once, look for a multi-port car charger that combines USB-A and USB-C outlets. These are cheaper than buying separate chargers and let you charge your phone, tablet, and smartwatch simultaneously. The trade-off is that you lose the convenience of wireless charging and must manage cables.

If your car has built-in wireless charging in the center console (some luxury EVs and recent models do), you do not need the Anker Nano. Use the factory charger instead, which is designed specifically for your car's interior and power system.

Frequently Asked Questions

Will the Anker Nano drain my EV's 12-volt battery?

No. Your EV's 12-volt system is separate from the main battery pack and is designed to power accessories like this charger. It recharges whenever you drive or plug in your car to charge the main battery. Leaving the charger plugged in while the car is parked will draw a tiny amount of power, but not enough to noticeably drain the 12-volt battery over days or weeks.

Can I use the Anker Nano while my phone is in a waterproof case?

Waterproof cases are usually too thick to allow wireless charging. The magnetic field cannot reach your phone's charging coil through the dense material. You would need to remove the case before charging. If you need both waterproofing and wireless charging, look for a thin waterproof case rated for Qi charging, though these are rare and expensive.

What happens if my phone overheats while charging?

Your phone will automatically stop accepting charge to protect its battery. The charging light on the Anker Nano may stay on, but no power will transfer to your phone. Once your phone cools down (usually within a few minutes), charging resumes. The cooling fan on the charger helps prevent this, but it cannot overcome extreme heat from direct sunlight or a very hot car interior.

Do I need to remove my phone case to use the Anker Nano?

Not always. Thin rubber cases under 3 millimeters usually work fine. Thick leather cases, metal cases, or cases with metal attachments will block the signal. Test your phone on the charger with your case on; if it does not charge, try removing the case. If it charges, you are good to go.

Can the Anker Nano charge my smartwatch or tablet?

Only if your smartwatch or tablet supports Qi wireless charging. Most smartwatches do not; most tablets do not either. Check your device's specifications. If it does support wireless charging, it should work with the Anker Nano, though the form-fitted cradle is designed for phones and may not hold a larger device securely.
