36 Volt to 5 Volt conversion

We are completing a college project and need to charge 8 smart phones simultaneously. We have a 36-volt battery and believe we need 5 volts and about 10 amps of power. Any suggestions, however broad, on how we might do this and what converter we might need? Thanks in Advance.

10 amps per smart phone or 10 amps total for all 8 ?

It's clearly 2A per phone, so 10A total.

If your project doesn't require building the DC-DC converter for charging phones and you don't want to build one, the quickest and easiest way is to buy a step-down converter module like this one: https://www.amazon.com/dp/B07Y7YB14L/ref=sspa_dk_detail_0?ie=UTF8&pd_rd_i=B07Y7YB14Lp13NParams&s=electronics&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWxfdGhlbWF0aWM&th=1
