Not Really Charger Related Increasing Amp Output From Bench Power Supply

Guy and girls, I have a Tenma 30 Volt 3 amp Bench Power Supply.

Is there a reasonable easy way to increase the ampage output, rather than buy a new one?

Sadly, not. Keep the 3 amp as a spare or sell it to a mate for what it’s worth, then buy a higher powered one. Good luck.
