I keep running out of canned air when I need to clean electronics. Do electric dusters work as well, and is there anything I should look for before buying one?
Are electric dusters worth it instead of canned air?

An electric duster is a practical replacement if you clean equipment regularly. You pay more upfront, but you aren't repeatedly buying cans, and a rechargeable model is easy to keep nearby.
Check the attachments, though. Some nozzles aren't as narrow as the straw on a can, which can make tight spots awkward.

I'd consider a corded blower if portability isn't the main concern. Some purpose-built models have a reputation for strong airflow and durability, although the cord is less convenient than a battery-powered unit.

Quality seems to vary quite a bit. Some small electric dusters get good feedback, while others have been reported to fail early or deliver underwhelming airflow. Look for substantial independent reviews rather than choosing on a big airflow number alone.

A compressor with adjustable pressure is another option if you already have one. Be mindful of moisture in the air supply and don't blast sensitive components at excessive pressure.

That makes sense for a workshop setup, though a small rechargeable duster may be easier to carry around.
