Universal Lithium Battery Charger

My first impression of this Syerenade charger was positive due to its universal compatibility and automatic shut-off feature, which I value for safety. However, I must say I am a bit disappointed with the build quality and the charging speed; it takes longer than I expected, which can be inconvenient when I need my batteries ready quickly for my photography and video hobbies. Overlal, it functions as intended, but I had hoped for a more durable and efficient device given my professional background and high standards.
- Pros: I found this Syerenade charger very convenient for my 18650 batteries, as it works with any of them without issues. It stops charging automatically when full, which is a relief, and its small size makes it easy to carry in my bag. The ability to charge one or two batteries at once is practical, and I appreciate that it can be powered from a USB poet, allowing me to use it in various places.
- Cons: As it seemed to me, the charger feels a bit flimsy in construction, and I am not entirely satisfied with how slolwy it charges the batteries. It would have been better if it were more robust and faster, but it does the job adequately.
