'Payphone' hitmakers Maroon 5 have offered up a selection of prizes for a charity auction that will raise money for a sick toddler.

Zoe Feldman, who turns 3-years-old this month, was diagnosed with sarcoma botryoides - malignant tumours of the muscles - and she must undergo chemotherapy to treat the condition.

The auction, set up on CharityBuzz.com, will help pay for Feldman's medical bills and the band have donated a signed guitar along with a meet-and-greet concert opportunity.

Frontman Adam Levine tweeted about the worthy cause earlier today (August 6) and urged fans to get bidding:

"Hey guys. Auctioning some sweet M5 items @Charitybuzz to benefit our friend Zoe Feldman... thank you!!!"

Maroon 5's lots will close on August 21 and the chance to meet Levine at a taping of The Voice is currently going for $3,250.
