{"product_id":"48v-booster-for-mark-3","title":"48V Booster for Mark 3","description":"\u003cp\u003eThe Zero Breeze 48V Booster is a DC-DC step-up converter that lets you run the Mark 3 portable AC from any 12V, 24V, or 36V power source in your rig — no 48V battery required. The converter block draws from your existing vehicle or house battery system and delivers stable 48V at 600W output through a 1.2-meter hardwired cable that terminates in the Mark 3's D20 connector. Efficiency is 85–90%, which means less waste heat and more run time from your available amp-hours.\u003c\/p\u003e\n\u003cp\u003eThe practical case: a 12V 100Ah house battery can power the Mark 3 directly through this booster for a meaningful stint at camp without any new high-voltage hardware. From a 12V source the booster pulls up to 55A, so fusing and wire gauge matter — the 60A fuse on the positive line isn't optional. Step up to 24V or 36V and current draw drops proportionally, which makes a 24V truck system or a 24V–36V lithium bank an easier fit. The included XT90 to Anderson terminal cable handles the input side; an optional XT90 to eye terminal cable (sold separately) connects directly to 12V battery posts if your setup doesn't have an Anderson connector.\u003c\/p\u003e\n\u003cp\u003eFits the Mark 3 only. Not compatible with the Mark 2 or any other equipment. If you're running a 12V system, confirm your battery can sustain 55A continuous output and route through a 60A+ fuse on the positive line before the booster. The booster is not UL\/CE certified for standalone use — it's designed as an integrated component of the Mark 3 power system.\u003c\/p\u003e\n\u003caside class=\"boondock-bill\" style=\"position:relative;overflow:hidden;background:#161719 radial-gradient(ellipse 60% 80% at 82% 28%, rgba(199,93,42,0.22) 0%, transparent 60%);border:1px solid #2D2E31;border-radius:12px;padding:24px 28px;margin:24px 0;\"\u003e\n  \u003ch3 style=\"margin:0 0 14px 0;color:#E37545;font-family:Geist,-apple-system,system-ui,sans-serif;font-size:18px;font-weight:700;letter-spacing:-0.01em;\"\u003eBoondock Bill's Take\u003c\/h3\u003e\n  \u003cdiv style=\"display:flex;gap:18px;align-items:flex-start;\"\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0576\/0404\/6931\/files\/xgrid-boondock-bill.png?v=1779057958\" alt=\"Boondock Bill\" style=\"width:88px;height:88px;border-radius:50%;flex-shrink:0;border:2px solid #C75D2A;background:#0E0F11;object-fit:cover;\"\u003e\n    \u003cp style=\"margin:0;flex:1;min-width:0;color:rgba(245,247,250,0.85);font-family:Geist,-apple-system,system-ui,sans-serif;font-style:italic;font-size:15px;line-height:1.6;\"\u003eThe Mark 3 wants 48V and most rigs don't have it — that's been the friction point since the unit launched. This booster removes that barrier without making you rebuild your electrical system. Bill runs it off a 12V house battery on the camper and it does what it says: the Mark 3 runs at full output, the fuse hasn't blown, and the Anderson connection makes it plug-and-play with any rig that's already wired for it. The 85–90% efficiency rating is why it doesn't get hot enough to be a concern.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/aside\u003e","brand":"Zero Breeze","offers":[{"title":"Default Title","offer_id":43265894383699,"sku":"B48","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0576\/0404\/6931\/files\/48V_Booster.webp?v=1763437598","url":"https:\/\/www.xgridoutfitters.com\/ga\/products\/48v-booster-for-mark-3","provider":"XGRiD Campers","version":"1.0","type":"link"}
