The best clock with USB charging is the one whose charging method and clock features fit your bedside routine. A USB port may provide only modest wired output, while some clocks add Qi wireless charging, alarms, radio or speaker functions. Compare the rated outputs, nighttime display controls, and what still works during a power outage before choosing.
What to check before choosing a clock with USB charging
- Charging method: Determine whether the clock has a USB port, Qi wireless charging, or both. A USB port does not mean the clock can charge a phone wirelessly.
- Rated output: Check the specified output rather than assuming a port is a fast charger. Also confirm which connector it uses and whether the required cable is included.
- Phone compatibility: Wireless charging requires a compatible phone. On a charging pad, placement and alignment can affect whether charging starts reliably.
- Clock functions: Consider whether you need one or two alarms, FM radio, Bluetooth audio, or snooze.
- Night use: Look for adjustable brightness or dimming, and check whether the display can be made comfortable for your bedroom.
- Power behavior: Backup batteries may preserve time or alarm settings, but that does not mean a clock can charge a phone during an outage.
- Size and style: Choose between digital and analogue displays, and consider whether a speaker or a particular finish is worth the added footprint.
How these four clocks differ
The specifications below are manufacturer-reported, not results of hands-on or comparative testing. Features, stock, and regional availability can change, so check the exact model listing where you plan to buy.
| Model | Charging | Clock and other features | Details to note |
|---|---|---|---|
| La Crosse Technology 617-148v2 | Qi-certified wireless charging rated at 5 W; separate USB output up to 1 A | Adjustable glow and display features | AC adapter included; USB charging cord not included. La Crosse lists the wireless output as “5 Watts” on its product specifications. |
| Philips TAR4406/37 | USB phone-charging port; output not stated on the product page | FM radio, dual alarm, adjustable display brightness | Battery backup is listed; the product page does not state its duration. |
| Geneva Lab Geneva Time | USB-A rated at 5 W; wireless charging rated at 10 W | Analogue alarm clock, Bluetooth speaker, AUX input | A design-led option with finishes shown on the product page. |

Choose by the kind of charging you need
For a wired connection
A USB port suits a phone you prefer to charge by cable, but output ratings vary. The La Crosse 617-148v2 specifies USB output up to 1 A, while Geneva Time specifies USB-A at 5 W. The Philips and Blaupunkt pages list USB charging without stating a comparable output rating. Check your phone’s charging requirements and the clock’s connector before relying on it as your main charger.

La Crosse 617-148v2 and Geneva Time specify wireless charging outputs of 5 W and 10 W, respectively. Blaupunkt describes the CR85WH Charge as Qi-compatible but does not state an output rating on its product page. Confirm that your phone supports Qi, and use the manufacturer’s instructions for placement. Wireless charging is a separate feature from USB charging, even when both appear on the same clock.
#1 Best Overall
- ✅【Dimmable Full Screen LED Display】This nightstand alarm clock charger has a 5.3X1.8 inch full-screen LED display that allows you to see the digits of time, even with your sleepy eyes not fully open. The 4-degree dimmable screen allows you to select from zero, low, medium, and full brightness to fit different lighting conditions of the room.
- ✅【Dual Alarm Setting with Snooze Function】You can set two independent alarms for the clock. When the alarm is ringing, press the DIMMER/SNOOZE/CLOCK button for a 9 minute snooze, which earns you invaluable time to wake up in a better mood.
- ✅【Convenient Nightstand Charger】[Convenient Nightstand Charger] Built with 3 AC outlets and 4USBs (5V/0-2.4A each, 4.8A/24W in total), this bedside charging station offer handy power access to your phones, tablets, nightstand lamp, radios, etc.
- ✅【Under Multiple Protection】This alarm clock charging station has a high strength casing made of ABS+PC material that are fire-resistant up to UL94 V-0 level. With the built-in 1700J surge protection, overload protection, over-voltage protection, over-current protection, short-circuit protection and overheat protection, your devices are well protected from multiple dimensions.
- ✅【Time and Alarms Back Up】With a battery chamber on the back to hold 2 AAA batteries (not included), this alarm clock will not shut down even when a power outage occurs or it is disconnected from the power source. Unlike other clocks that solely rely on battery power, the batteries in this power strip alarm clock work longer as they are for backup.
Check alarms, displays, and backup separately
A clock’s backup function and its phone-charging behavior answer different needs. Philips lists battery backup alongside its dual alarm, and Blaupunkt specifies a CR2032 backup battery that is not included. Those details concern clock features; they should not be read as a promise that a phone will charge without mains power.
For the La Crosse C86224, La Crosse support says the USB ports charge devices when the clock operates on AC power. This is a different model from the 617-148v2, but it illustrates why power behavior should be checked for the exact clock rather than inferred from the presence of a USB port. See La Crosse’s C86224 USB charge-port support article.

- Digital Clock Alarm Clock for Bedrooms: Peakeep gathers all features you rely on a clock for your bedroom, such as precise and clearly visible numbers, a loud alarm with snooze and volume control, adjustable display brightness, 1 USB charger, and even a backup battery alarm in case of power outages
- Large Numbers Digital Clock: 2-inch height of large digits can be seen from a greater distance, providing a clear and easy way to keep track of time. Big numbers make it easier for seniors and elderly with poor eyesight or those who struggle to read small fonts or simply prefer a larger display to read the time
- Loud Alarm Clock with Volume Control: 5 settings of volume control for the alarm enable the clock to be super loud for heavy sleepers or those who have trouble waking up. It also allows you to set the alarm to a lower volume to help protect your hearing while still waking you up. 9-min snooze can be helpful if you like to catch a few extra minutes of sleep in the morning
- Digital Clock with Adjustable Brightness: 5 different brightness settings ensure clock time is always visible in various lighting conditions. You can customize the brightness to your preference to get eye comfort and improve sleep by adjusting the display to a lower brightness level or completely off at night
- Electric Alarm Clock with Battery Backup: With a powerful AC/DC adapter included, this digital LED clock is able to run smoothly and accurately. Additionally, the clock requires 2 AAA batteries (not provided) to memorize your settings and trigger the alarm, this way, in the event of power outage, you won't oversleep or worry about resetting the time
For bedroom use, compare the stated dimming or display controls with how dark you want the room. Philips lists adjustable display brightness, Blaupunkt lists adjustable dimming, and La Crosse describes adjustable glow and display features. The cited product pages do not establish a shared brightness scale, so the feature names alone do not show which clock gets dimmest.
Match the form factor to your bedside
Geneva Time combines an analogue alarm clock with Bluetooth speaker and AUX input, while the Philips and Blaupunkt examples are clock radios or digital alarm clocks with additional functions. A speaker-clock combination can reduce the need for another bedside device, but it may take up more space than a simple clock. Check the product’s dimensions and finish options before deciding whether its styling and extra audio features suit your room.
