This cordless hand mixer works great while charged. It is very convenient to not have to be attached to a cord while mixing or have the cord get in the way. However, this mixer doesn’t stay charged for very long. You can "power charge" it but that is not quick! Takes 2 ho0urs to fully charge but you can get an extra 25 seconds after charging for 10 minutes. If I'm in the middle of mixing something and the battery dies, I'm not going to want to wait 10 minutes just to get a few more seconds of mixing. Luckily while fully charged you should have enough battery life to get just about anything mixed.
