Solid-state cells use a solid electrolyte instead of the liquid electrolyte found in standard lithium batteries, which delivers two real-world advantages: roughly twice the energy density per pound of battery (so the unit is dramatically lighter for its capacity), and significantly improved thermal stability (much harder to enter thermal runaway).\u003c\/p\u003e \u003cp\u003eThe B4000 SST delivers a 4,000 Wh peak \/ 2,611 Wh continuous battery package with 4,000 W of pure sine wave AC output (8,000 W surge), enough to power most household appliances simultaneously — including high-draw items like microwaves, electric kettles and full-size power tools. The unit weighs noticeably less than a comparable LiFePO4 power station of similar capacity, making it more practical to move around the house, garage, RV or job site.\u003c\/p\u003e \u003cp\u003eCharging is fast: up to 1,800 W from a wall outlet recharges the unit in roughly 1.5 hours, and the integrated MPPT solar controller accepts up to 1,000 W of solar input. Outputs cover 6× pure sine wave AC, 100 W USB-C PD, USB-A QC, a 12 V car port and a 30 A RV-style outlet. Yoshino backs the unit with a 5-year limited warranty.\u003c\/p\u003e \u003ch3\u003eKey Specifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eBattery: 4,000 Wh peak \/ 2,611 Wh continuous solid-state\u003c\/li\u003e \u003cli\u003eAC output: 4,000 W continuous \/ 8,000 W surge\u003c\/li\u003e \u003cli\u003eCharging: 1,800 W AC, 1,000 W solar (MPPT)\u003c\/li\u003e \u003cli\u003eOutputs: 6× AC, USB-C PD 100 W, USB-A QC, 12 V, 30 A RV\u003c\/li\u003e \u003cli\u003eAdvantages: lighter, safer thermal profile vs. lithium-ion\u003c\/li\u003e \u003cli\u003eWarranty: 5-year limited\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003c!-- robessa-gmc-v2-start --\u003e\u003c\/p\u003e \u003cdiv class=\"robessa-trust-row\" style=\"flex-wrap: wrap;gap: 12px;margin: 18px 0\"\u003e \u003cdiv style=\"flex: 1 1 200px;border: 1px solid #e5e7eb;border-radius: 10px;padding: 12px 14px;background: #fafafa\"\u003e \u003cdiv style=\"font-weight: 600;font-size: 14px;color: #111\"\u003e🚚 Free Shipping\u003c\/div\u003e \u003cdiv style=\"font-size: 13px;color: #555;margin-top: 4px\"\u003eOn every order, shipped from our facility in Piedmont, SC.\u003c\/div\u003e \u003c\/div\u003e \u003cdiv style=\"flex: 1 1 200px;border: 1px solid #e5e7eb;border-radius: 10px;padding: 12px 14px;background: #fafafa\"\u003e \u003cdiv style=\"font-weight: 600;font-size: 14px;color: #111\"\u003e🛡️ Full Manufacturer Warranty\u003c\/div\u003e \u003cdiv style=\"font-size: 13px;color: #555;margin-top: 4px\"\u003eBrand-new, authentic product with the full factory warranty.\u003c\/div\u003e \u003c\/div\u003e \u003cdiv style=\"flex: 1 1 200px;border: 1px solid #e5e7eb;border-radius: 10px;padding: 12px 14px;background: #fafafa\"\u003e \u003cdiv style=\"font-weight: 600;font-size: 14px;color: #111\"\u003e🔒 Secure Checkout\u003c\/div\u003e \u003cdiv style=\"font-size: 13px;color: #555;margin-top: 4px\"\u003eSSL-encrypted payment with major cards \u0026amp; PayPal.\u003c\/div\u003e \u003c\/div\u003e \u003cdiv style=\"flex: 1 1 200px;border: 1px solid #e5e7eb;border-radius: 10px;padding: 12px 14px;background: #fafafa\"\u003e \u003cdiv style=\"font-weight: 600;font-size: 14px;color: #111\"\u003e↩️ Easy Returns\u003c\/div\u003e \u003cdiv style=\"font-size: 13px;color: #555;margin-top: 4px\"\u003e90-Day Free Returns — no restocking fees, no hassle.\u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv class=\"robessa-faq\" style=\"border: 1px solid #e5e7eb;border-radius: 10px;padding: 16px 18px;margin: 18px 0;background: #fff\"\u003e \u003ch3 style=\"margin: 0 0 10px 0;font-size: 16px;color: #111\"\u003eFrequently Asked Questions\u003c\/h3\u003e \u003cdetails style=\"border-top: 1px solid #f1f1f1;padding: 10px 0\"\u003e \u003csummary style=\"cursor: pointer;font-weight: 600;color: #111;font-size: 14px\"\u003eHow long will this power station run my appliances?\u003c\/summary\u003e \u003cdiv style=\"margin-top: 8px;color: #444;font-size: 14px;line-height: 1.6\"\u003eRun time depends on appliance wattage.
