Anker is the shit! They have one for maybe $70 that’s designed for a Nintendo Switch. You can charge your phone at a great rate. The pack itself lasts probably a few days with some nightly charges. They sell them at Target https://www.amazon.com/dp/B07DMFL3SJ/ref=cm_sw_r_cp_api_glt_fabc_4S8G5PPW8YHGHTFXRQKX?_encoding=UTF8&psc=1
