Overview
Big numbers are the point here: 2 inch jumbo LED digits, a brightness dimmer, adjustable alarm volume, a 9 minute snooze and a USB charging port on a corded clock built for reduced-vision reading.
DreamSky built this one around visibility and control rather than extra functions: display brightness and alarm volume can each be dialed in separately instead of fixed. It runs on its included AC adapter only; two AAA batteries, not included, back up the clock memory during an outage but will not power the display or sound the alarm on their own.
- 2 inch jumbo LED digits with adjustable brightness dimmer
- Adjustable alarm volume, 30 to 90 dB, with 9 minute snooze
- USB charging port for a phone or small device
- AC adapter powered; AAA batteries back up memory only
Who it's for
Works well for anyone with reduced night vision, a bedroom where a dim display matters, or a teen who needs a genuinely loud alarm. Not the right pick for someone wanting a battery-only travel clock.
Pros and cons
- Large 2 inch digits, readable across a room
- Multiple brightness levels, including a true dim setting
- Alarm volume adjustable, 30 to 90 dB
- USB port for charging a phone
Performance notes
The USB port charges a phone without a separate wall adapter. Power comes from the included AC adapter; AAA batteries only preserve the clock and alarm settings in memory during a power cut.
