I like chargers with clear indicator lights because they tell me at a glance whether the battery is charging, full, or has an issue. Simple controls matter to me too, since I want a charger that works without any confusion.
Power Source and Convenience
I check whether the charger needs a standard outlet and how much space it takes up near my workstation. If I plan to charge batteries in a vehicle or on a mobile setup, I think about how practical the charger will be in that environment.
Price vs Value
I do not always choose the cheapest option. Instead, I look at the value I get for the money. If a charger saves me time, lasts longer, and supports more batteries, I usually feel it is worth paying a little more.
