Smart Locks with USB C Charging for Modern Homes
The Ultraloq U-Bolt Pro WiFi stands out as the best smart lock with USB C charging for most users, offering a fingerprint reader, multiple entry methods, and a USB C port for backup power. Its main advantage is the convenience of using a common cable to jumpstart the lock when the battery dies. The main limitation is that it requires a WiFi bridge for remote access, which is sold separately, though Bluetooth works out of the box.
Smart locks have evolved beyond simple keypads. Many now include USB C ports for emergency charging, which is a game changer for forgetful users. Instead of hunting for a 9V battery, you can plug in a phone charger and unlock your door.
In this roundup, we look at locks that offer USB C backup, ranging from budget-friendly models to premium smart locks with fingerprint sensors. We compared specifications and user reviews to help you find a reliable and secure option.

Frequently asked questions
How does USB C backup charging work on a smart lock?
When the battery is too low to operate, you can connect a USB C power source to the designated port on the lock. This provides temporary power to the lock’s electronics, allowing you to enter your code or use the app to unlock the door, after which you should replace the batteries.
Do all smart locks with USB C have the port on the outside?
No. Some models, like the Ultraloq U-Bolt Pro and Schlage Encode Plus, have a USB C port on the exterior for emergency access. Others, such as the August Wi-Fi Smart Lock, have the port only on the interior, which is less useful if you are locked out.
Can I use any USB C cable to power the lock?
Yes, in most cases you can use a standard USB C cable connected to a power bank, laptop, or wall charger. However, some locks may require a specific voltage or current, so always refer to the manufacturer’s instructions.
What is the battery life of smart locks with USB C?
Battery life varies by model and usage. Most use AA batteries that last 6 to 12 months. Locks with additional features like cameras or WiFi may have shorter battery life. USB C backup is not a primary power source but a temporary solution.
Are smart locks with USB C more expensive?
Not necessarily. The price depends on the features and brand. You can find budget models like the Kwikset Halo with USB C, as well as premium options like the Schlage Encode Plus. USB C is becoming a standard feature, so it does not significantly affect the price.
Can I install a smart lock with USB C myself?
Most smart locks are designed for DIY installation and come with detailed instructions. You only need a screwdriver and about 30 minutes. However, if you are not comfortable with tools, you can hire a professional installer.
Do smart locks with USB C work with Apple HomeKit?
Some do, like the Schlage Encode Plus and August Wi-Fi Smart Lock. Others support Alexa and Google Assistant but not HomeKit. Check the specifications before purchasing if HomeKit is important to you.
What happens if the USB C port is damaged?
If the USB C port is damaged, you can still use the physical key if the lock has one, or you may need to replace the lock. Some locks have an alternative backup, like a 9V battery terminal, but not all.
Are smart locks with USB C secure?
Yes, they offer similar security to other smart locks. However, always choose a reputable brand and enable two-factor authentication in the app. Physical security features like the deadbolt mechanism also play a role.
Which smart lock brand is most reliable?
Brands like Ultraloq, Schlage, Yale, and August are well regarded for their reliability. However, individual experiences vary. Reading user reviews and checking for firmware updates can help ensure a positive experience.
