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, business or off-grid 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.

Great Product
I have used the B4000 for around six months in my house and RV. During power outages it will operate my furnace for a couple of days. We also use it to operate electric heat in the truck when parked at rest stops in the winter. We have also powered our residential RV fridge while driving long distances to save the house batteries for other uses. At 53 pounds I can move ...

Simple solutions are the best !
I've had my B4000 for about 6 months and it is perfect for my Lance 1172 Truck Camper. Covers all my energy needs and as you can see is not in the way. The picture shows it charging up when I'm connected to show power.
It can run my AC for about 2 hours and easily runs all the other 120v stuff through its own inverter, the toaster, microwave and coffee pot when I'm boon...

Lot's of power
I bought the B4000 for stand by power and I used my it to power my camper and it worked flawless, and had enough power to rum the A/C. I was impressed that the charge was still full after sitting through the winter.

E Cubed = Economical Efficient Environmental
Purchased my B4000 3 months ago for my 30-amp Lance Truck Camper. Truck Camper is awesome, it allows you to camp anywhere a car could go. But didn’t want to start the generator in the early AM so as not to disturb the campsite.
Got to have my coffee (coffee maker), warm oatmeal (microwave) and of course toast (toaster oven) very early in the morning. All need high ampe...

No power, No problem. The project goes on.
Bought this for peace so I'm not so dependent upon the grid. Very satisfied.

More Than Expected
I purchased two of these units with solar panels for emergencies and have been using them to supplement electric bills while waiting for that big emergency. This is a win win for me. Am waiting for additional battery packs to ad to units. Performance so far is much better than expected.

It's been working great because it's not as heavy as others. The price was right also.

Great Capacity for camping trips.
I bought this battery a few months ago to power my CPAP and also, my portable BougeRV refrigerator/freezer while on remote camping trips. Last week, we were in a primitive area adjacent to Big Bend National Park for 7 days. Together, these two items pulled between 550 to 600 watts a day. After 4 days, the battery was down to under 10 percent charge. I had anticipated th...

Happy with my B4000 SST
nice product works well and I love to extra safety it provides. The charging pads on top basically do work. I would be nice if the AC output switch was on both sides on the generator. I charge the unit from AC when it’s sunny and my solar system is over producing and run my TV entertainment system at night from the BA4000 given me all the power I need all night. I use a...

amazing form factor and worth the cost
I spent a lot of time researching portable battery backup and I am very happy I purchased this unit even though it was more expensive than others I considered. The form factor is excellent and well thought out. For the weight, it provides the kWh I was looking for. I am sold on the solid state technology and have purchased the B660 too. I look forward to seeing what els...

I do not like it! I LOVE IT!
Needed something for continued power outages in our area. Plus the mobile ability for “on the go” in both of our RVs and multiple recharging applications.
Lots of great features trumped by only 53 pounds made it by far the obvious choice for us. Charges fast on 110, waiting for solar (extension) cables to arrive Saturday to learn to charge with solar.

Impressed!... So far
Recent purchase; great so far. Intended use is part of home power back up. Tested on a high wattage LED grow lamp for 12 hours with less than 25% storage consumed.
3× 200W solar not connected yet. Also waiting on additional batteries. Will see what energy I can pull in and revise my review at that time.

So far it's great, charged up quickly. I plan to take it on sculpture installations and cleanings to run various electric power tools.

Great! Fast charge time and it powers alot of household items. Still trialing it but I must say it does what I need it to do as a home backup and camping use

So far it’s producing the power I expected. The noise level is a little high to operate inside for a long periods of time and there is some heat so it would need to sit outside in the summer. I did notice when the unit is unplugged I could feel some current if I touch the male plug-in charging cord. I’m concerned that there could be ceo be back feeding into my circuit.
