Whetstone Cutlery Dynamo Hand-Crank Solar Lantern 1 Pack — 180 lm, USB Output, 1200mAh

Compact and built to be dependable, this Whetstone Dynamo Hand Crank Solar Powered Lantern combines a 1200mAh rechargeable battery, a solar panel, and a manual dynamo to keep light and power available when outlets are not. The 36-LED array produces up to 180 lumens with bulbs rated for long life while a built-in USB port lets you charge phones or small electronics. Multiple powering options — dynamo crank, solar charging, 3 AAA batteries, or an AC adaptor port — make it a versatile addition to camping kits, emergency bags, and vehicle trunks.

How do I power and recharge this lantern when I’m off-grid?

The Dynamo lantern is designed for flexibility: use the built-in hand crank for immediate power, place it in sunlight to recharge via the solar panel, insert 3 AAA cells, or connect an AC adaptor to the charging port. A full solar charge typically takes about 6 hours, while manual cranking delivers approximately 20 minutes of light for every minute of cranking.

• Included 1200mAh rechargeable battery for repeated use.
• Hand crank provides emergency charging without supplies.
• Solar panel supports roughly 6 hours to recharge fully in good sun.
• Compatible with 3 AAA batteries or an AC adaptor (charger not included).

What brightness and runtime can I expect from the LED lamp?

The lantern's 36 LEDs are rated up to 180 lumens and offer three brightness levels—high, medium, and low—so you can balance light output against battery life. LEDs are long-lasting, minimizing bulb maintenance, and the adjustable modes help extend runtime while reading, cooking, or signaling.

• High, medium, and low settings to match tasks and conserve power.
• LED life expectancy up to 100,000 hours under typical use.
• Use lower settings for longer duration in multi-day situations.

Can this lantern charge my phone or power small devices?

Yes — the Dynamo includes a USB output that serves as a portable power source for phones, tablets, and other small electronics when no wall outlet is available. Keep in mind the 1200mAh internal battery will provide limited charges; extended device charging is possible with frequent recharging via solar or crank.

• USB port for emergency charging of phones and small gadgets.
• Best used to top up batteries or provide vital calls and navigation.
• Combine cranking and solar input to extend available USB power.

What physical features make this lantern practical for outdoors and emergencies?

The unit is compact and lightweight with a sturdy carry handle and a hanging hook for convenient placement in tents or on walls. Constructed from plastic and metal, it measures about 5.25" long by 4" wide and 10" high, making it easy to stow in kits while still offering a solid beam for campsite and household use.

• Carry handle and hook for hanging in tents or rooms.
• Durable plastic-and-metal construction for rugged use.

Who is this for? The Whetstone Dynamo lantern is made for campers, hikers, and anyone assembling an emergency or vehicle kit who needs dependable, multi-source lighting and occasional USB power without relying solely on wall chargers. It’s also a practical choice for households that prefer a portable, rechargeable lamp for power outages, night-time outdoor tasks, or travel where electricity is limited.
