Frequently Asked Questions
Does this charger have built-in protection against overheating or power surges?
Yes. Anker builds in overvoltage protection and a temperature control system designed to keep the charger operating within safe limits, which is especially reassuring for overnight and bedroom use.
Is it safe to leave this charger plugged in overnight while I sleep?
Yes. The charger is designed for continuous use, includes temperature monitoring, and once your device reaches 100 percent the charger tapers output, so leaving it plugged in overnight is a normal use case.
Is this a safer choice than a cheap no-name USB-C block from online marketplaces?
Yes. Anker is a recognized brand with established safety testing, an 18-month warranty, and published protection features, which makes it a much safer bet than unbranded chargers that often skip proper overvoltage and temperature safeguards.
Can I use this charger in an older home with mixed wiring without worry?
The 240V universal input means it accepts a wide range of voltages safely, and the built-in protection circuitry is designed to handle minor fluctuations in household power without damage to the charger or your device.
Will the charger get hot to the touch during fast charging?
All 20W chargers produce some warmth under load, but the temperature control system is designed to keep surface temps within safe limits, and the charger should feel warm rather than hot during normal use.
How does this compare to using an open-flame candle or oil burner for safety?
Unlike a candle, this charger has no flame, no hot wax pool, and no burning scent, so there is no fire risk around children, pets, or bedding, and no smoke or soot to worry about in a closed room.
Is the USB-C cable safe to leave plugged in around a toddler or pet?
The cable is a standard low-voltage USB-C cable that only carries power when a device is connected, and the charger itself shuts off output when nothing is plugged in, so there is no live current at the cable end when idle.
What happens if there is a power surge while the charger is in use?
The overvoltage protection circuitry is designed to absorb small surges and shut the charger down safely in the event of a larger spike, protecting both the charger and the connected device from damage.
I have had chargers fail before. What is the warranty if something goes wrong?
Every Anker 2-pack is covered by an 18-month warranty, so if the charger fails under normal use within that period, Anker will replace it, which significantly reduces the risk compared to no-name alternatives.
How do I set up the Anker 20W USB-C charger for the first time?
Plug the charger into any standard wall outlet, connect the included 5 ft USB-C cable to the USB-C port on the charger, and plug the other end into your iPhone or other USB-C device. Charging begins automatically, and no software or app setup is required.
Can I use a longer USB-C cable if the included 5 ft one is not long enough?
Yes. The charger works with any standard USB-C to USB-C or USB-C to Lightning cable, so if you need a 6 ft, 10 ft, or right-angle cable for your setup, you can swap in a higher-quality third-party cable without affecting charging speed.
How do I know if my device is fast-charging versus standard charging?
On iPhone, when fast charging is active you will hear the familiar double charging chime and see the charging status on the lock screen. On Android, a small fast-charging or quick charge indicator usually appears in the status bar or lock screen.
Does this charger work with iPhone 12, 13, 14, 15, and 16 series?
Yes. Any iPhone from the 8 onward supports USB Power Delivery fast charging, and the 20W output is exactly the wattage Apple recommends for the fastest safe charge on iPhone 12 through iPhone 16, including Pro, Plus, and Pro Max models.
Will it also charge Android phones, iPads, wireless earbuds, and smartwatches?
Yes. The USB-C PD port supports most Android phones that use USB-C, USB-C iPads, and USB-C earbud cases, while the USB-A port is compatible with older device cables including Apple Watch chargers and standard wireless earbud cases.
What is included in the box when I open the 2-pack?
Each box contains two Anker 20W USB-C wall chargers and two 5 ft USB-C to USB-C cables, along with a quick-start guide and the 18-month warranty information. No additional accessories are required to start charging.
Is it normal for the charger to get warm during use?
Yes, mild warmth is normal, especially during 20W fast charging. The charger is designed with temperature control to keep operation within safe limits, so warm-to-the-touch is expected, but it should never be uncomfortably hot.
Will this charger damage my phone battery if I leave it plugged in overnight?
No. Modern iPhones and the charger's power management work together to taper charging once the battery reaches 100 percent, so leaving the phone plugged in overnight is a normal and safe use case for this charger.
What is the difference between a USB-C PD charger and a regular USB charger?
A regular USB charger typically outputs 5W to 12W, while a USB-C Power Delivery charger like this one can output up to 20W and negotiates the optimal voltage with your device, which is what enables iPhone fast charging from 0 to 50 percent in about 30 minutes.
