Tips to choose mini flashlight
When you find mini pocket flashlight, I guess you may not expect how bright the flashlight is since mini flashlight only powered by 1 AAA battery. Here, I have some tips for choosing such flashlights.
1. Brightness. The brighter the flashlight is, the faster the battery runs out. So, you'd better choose that have different modes which can meet different needs.
2. Waterproof. Waterproof flashlights are recommended since they can work on rainy days
