This portable power station is an essential battery-powered backup system that will allow you to become more self-sufficient whether using it for outdoor, home backup, recreational, or business use.
- ADVANCED SOLID-STATE TECHNOLOGY—Solid-state technology (SST) is the evolution in lithium batteries, which provide safer, more compact, and lighter power output than their conventional lithium-ion or LiFePO4 counterparts. The new solid-state battery provides safer and more compact power for off-grid and recreation use.
- SAFETY FIRST - Yoshino solid-state battery cells provide a peace of mind that the competition leaves out; Yoshino has full ETL certification on all its portable power stations and has been tested by Energy Assurance Labs (accredited third-party lab in the United States) undergoing nail penetration tests along with thermal runaway tests (no flammability issues like traditional lithium batteries), over voltage, over current, over charging, over discharging and short circuit protection.

so far the BOMB. Received quickly tks to Martin who matched some price offers. be careful... most all devices using a hot plate induction heater coils draw between 1000-1.5KW of power. consequently, you will need to find a devices that draw closer to 1/2 this amount. I did manage to find a small programmable MR. COFFEE maker that draws only 640W which is a perfect 'FIT'...

Simple yet useful!
I bought this for my husband because he loves to go outdoors and he loves it. Sometimes he likes to use it at home even to charge his gadgets such as his drone and media devices.

perfect for my cabin
I previously bought the B4000 SST and wanted a smaller unit for my cabin and I am pleased with the B660 SST. It has the same high quality form factor as the B4000 and has met my expectations. I like being able to monitor the unit with the app when I am away from the property. I am looking to purchase more B660s and B4000s in the near future for my other properties.
