I recently got to try out the Energizer X400 Rechargeable Pen Light and I am here to give you my honest review.
Firstly, the design of this pen light is quite impressive. Its really small and lightweight, making it perfect for carrying around in your pocket or bag. The aluminum construction makes it feel very durable, and the black finish gives it a sleek, modern look. The LED technology provides bright, directional illumination, so you can see up close in the dark with ease. Additionally, this penlight is IPX4 water resistant and impact resistant up to 1 meter which adds to its durability.
The battery life is also great. On High mode, it can put out 400 lumens for up to one hour, while on Low mode it can put out 125 lumens for up to three hours. This makes it great for a variety of uses such as camping trips or emergency repairs in the dark. Its also rechargeable so you dont have to worry about running out of batteries when you need them most.

The included USB charging cable is also nice as it makes recharging the penlight a breeze. All you have to do is plug it into any USB port or wall outlet and youre ready to go.
