Which solar-powered flashlight is best?
When the power goes out or your car breaks down, the last thing you want is a flashlight with dead batteries. A solar-powered flashlight gets energy from the sun, theoretically offering an endless light source for as long as you keep it charged.
If you’re interested in buying a solar-powered flashlight, the NPET T09 Solar Flashlight is an excellent choice because it has seven different light modes and many features.
What to know before you buy a solar-powered flashlight
Consider how you intend to use your solar-powered flashlight before deciding on a model. Many of these products are designed specifically for outdoor activities such as camping or hiking, while others specialize in home use and vehicle emergency kits. Outdoor flashlights tend to be more durable and are commonly waterproof. A flashlight for the home or your car can be larger since pack weight isn’t an issue, and these devices typically have features like USB ports for charging your phone.
While a solar-powered flashlight gets most of its power from the sun, many flashlight models feature some kind of supplemental charging method you can use in a pinch.
- Hand-crank flashlights: This charging method is on many durable outdoor flashlights. Simply turn the crank for a few minutes and you’ll receive about an hour of charge. This method is convenient for outdoor activities because you can quickly get a solid charge in any environment.
- USB powered: Some indoor solar-powered flashlights have standard USB ports as a supplemental charging method. For best results, completely charge your solar-powered flashlight via USB to provide a baseline charge, then use the power of the sun to regularly top it off.
Lumens and brightness
The vast majority of solar-powered flashlights use LED bulbs because they provide more brightness while using less energy. The brightness of a flashlight is measured in lumens. A product that boasts many lumens may be tempting, but keep in mind that bright light can quickly drain a flashlight’s energy.
What to look for in a quality solar-powered flashlight
Most solar-powered flashlights can hold a charge for around four to 10 hours. Look for a flashlight with an optional low light setting, as this will maximize your charge time.
Depending on the additional charging methods included, it may take your solar-powered flashlight a few hours before it reaches a complete charge. The size of your flashlight’s solar panels and the time of day can also impact charging time.
Many solar-powered flashlights have various light modes that conserve energy or draw attention in case of emergency. Some standard light modes include flashing red lights and high-intensity brightness.
Given their usefulness in emergencies, many manufacturers have incorporated relevant accessories into the design of their solar-powered flashlights. These could be lifesaving or simply convenient, but if you want more bang for your buck, look for a flashlight that has any of the following features:
- Seatbelt cutter: Often found alongside a window breaker, you can use this tool to free yourself from a car.
- Phone charger: Almost exclusively found on models with a supplemental USB port, this feature will drain your flashlight quickly but is helpful in an emergency.
- Compass: These small yet crucial tools are on outdoor solar-powered flashlights.
- Waterproof: Look for this feature if you need a flashlight to take kayaking or boating.
- Magnet: Some models have magnetic strips that let you attach the flashlight to a metal surface such as a car, making them well-suited for vehicle emergency kits.
How much you can expect to spend on a solar-powered flashlight
Expect to pay $10-$30 for a solar-powered flashlight, regardless of its intended purpose.
