The Liitokala 3500LM Keychain Flashlight is a surprisingly potent tool that I have been testing as part of my daily carry routine. It manages to pack a heavy-duty punch into a frame small enough to clip onto a set of keys, making it a constant companion for late-night tasks.
Constructed from a robust mix of ABS and aluminum, this light feels substantial and ready for rough conditions. The waterproof design adds a layer of confidence, ensuring it holds up even when you are caught in the rain or working in damp environments.
The stepless dimming feature is the standout highlight, allowing me to transition smoothly between subtle lighting and a full 3500-lumen beam. Because it recharges via USB, I never have to worry about digging for spare batteries when the power runs low.
This is the perfect tool for professionals who need a high-output work light that fits discreetly in a pocket or on a keychain.
Overall, this light earns its 4.84/5 rating by delivering consistent, powerful performance in a tiny package. At $64.90, it is a smart, durable investment for anyone needing reliable light in 2026.
