BLUETTI Portable Power Station EB55, 537Wh LiFePO4 Battery Backup w/ 4 700W AC Outlets (1400W Peak), 100W Type-C, Solar Generator for Outdoor Camping, Off-grid, Blackout (Solar Panel Optional)

This is my second Bluetti portable power station. I'm in a home with fairly small power needs in multiple rooms. I work from home, so I have to have all of my "office" technology up and running at all times. Well, I have a FIOS ONT box in one room, a router/modem in another room, and I generally use my laptop in yet a different room!Many people try to get the largest solar generator/power system they can afford, but my goal is to get the sizes that work to keep me working, even if that means I have to purchase a few of them. Eventually, I'll get one large enough for a power sucking fridge/freezer, but for now, my priorities are work.There are a lot of companies to choose from, but after doing a lot of research, I found that not only did Bluetti have great technology, but they also have great customer service when it counts. I've not had the need to test the customer service yet, as I've had ZERO issues with my units.The EB55 is very similar to the EB70, with a couple of small differences. The EB 55 has specs of 537WH/700W, which means I don't get quite as much time with it, but I do get the same amount of watts that can be pulled at the same time. That 700W is a great spec for the price!. The biggest thing that pushed me toward these new Bluetti units is the LiFePO4 batteries they are using. I love that the number of times you can charge the unit, via any of the methods, is 2500+. That is phenomenal! I can charge my unit every day and not worry about having to replace it for years!Now, about the charging....... it will accept up to 400watts to charge it, so that means I can charge it FAST! I have one of the Bluetti SP200 solar panels, and I plan to get a second one when I can afford it. I should be able to charge this puppy up in about 2 hours with the second panel. One of the biggest differences with this unit is the ability to charge using two chargers if you have you them, and an adapter. I intend to get the adapter, as I have the charger from the EB70 that should work also. I want to be able to fast charge if I know a power outage is possible and I want to be able to fast charge during a power outage. The EB55 will let me do both.I'm not going to list all of the technical specs, because for people reading solar system reviews, you should have already done your homework on how they work and what you are looking for. I can't stress enough that you should watch video after video after video from reputable Youtubers before you jump into the solar field. There's a lot of information to absorb, and most people need some time to absorb it.PROS:LiFePO4 battery - great life cycle with this700wattsFast charging with two input ports - this is a huge improvement over any other manufacturer4 AC ports - this is a big plus for a unit this sizeNice light on the back side - this was an improvement over the EB70Wireless charging on top of unit (I don't use it, but many people would)Reputable manufacturer - High value with this feature. Many others don't even reply to you, based on reviews I've readCONS:Not horrible, but the battery gauge is just a bar system that jumps by 20% increments, instead of telling you exactly how much power you have remaining in your unitOVERALL:Would I purchase again? You bet I would? And I probably will. This is a great portable solar power station and living in Florida, I'm grateful to have it.

My first Bluetti product! As a retired electrical engineer, I tried to summarize what everyone wants to know:GOOD:+Hard cardboard outer shipping box and well designed product box gave fantastic shipping protection (and looked great!)+Quality of unit is outstanding. Fit/finish, buttons/connectors and LED display are all of high quality and work well+Easy to carry around (folding handle, stows to allow stacking flat items on top of unit); however, it is not a "light-weight" box+LiFePO4 batteries! Long battery life (and the best cycle life of any battery chemistry)+Double charging input capability (200W wall brick and 160W solar); can also charge from your vehicle's cig lighter port while driving+Bluetti put the very capable EB70 700/1400W full-sine inverter in this box. It was capable of running my small refridg/freezer (which has a 6.5 FLA/780W rating) for over 4 hours (87W running) or that fridge plus my eBike charger for 2+ hours, total 270W)+100W USB-C charging port can power/charge USB-C input laptops+After discharging to 20% (fridge/eBike charger loads) I was able to fully recharge the EB55 in 2+ hours with 200W of solar panels at 102F ambient (if temps were cooler it would have been 1+ hour)+Finally, the "lantern" light is MUCH more usable than the "flashlight" variety on other SoGens (Solar Generators, a term trademarked by Hobotech, excellent reviews AND purchasing discounts: https://hobotech.tv)BAD:-IF you need... over 700W continuous AC power (you'll likely need a larger battery pack as well, e.g. EB150, EB240 or AC200P)... over 500Wh capacity (buy a larger-capacity battery, e.g. EB70 at 700Wh or any of those mentioned above)... to know the exact amount of charge left on the battery, the LED display does not show % of charge directly, it just has a 5-bar display (20% each bar); if you never discharge below ~20% then no big deal... two 100W USB-C ports (buy the EB70!)... silent charging (AC brick fan runs continuously, MPPT solar charge controller runs the internal fans)-You can't use a residential/business solar panel since the VOC of those panels is too high for the EB55 solar input; just get ~200W of a standard "12V" hard panel (e.g. BOUGERV 200w) or a suitcase/folding type (Renogy 200W/Bluetti SP200-do not use the charge controllers provided on these, wire straight from the solar panels!)SUMMARY:Highly recommended if your loads/capacities are within the limits of the box. This will last you a LONG time and Bluetti is very responsive to issues/warranty (likely will never need service!)Instruction booklet error: LCD SCREEN GUIDE "How to operate on power station to turn ON/OFF ECO Mode/and change the working frequency" section appears to have been copied directly from the EB70. To enter the settings mode you press the AC and [lower USB!] DC buttons, EB70 only has one DC power button, EB55 has two-the USB DC switch is the one to use to enter/set the menu.Finally I recommend you join the "Bluetti Portable Power Station" Facebook group. You may have a question that others are thinking about (or has already been answered)!

I bought the Bluetti EB55 as a preview to my AC300 purchase which will be delivered in November. The EB55 has many outlets including a Wireless smartphone charging pad on the top. It is the smallest and newest power station for its capacity and that uses the best cell chemistry LiFePo ( Lithium Iron Phosphate) available for home use because it does not suffer from thermal problems as with older chemistry. It comes with its own 200 watt AC to DC charger ( with integrated cooling fans) and two extra cables for vehicle (12V) and for solar panel charging, limited to 24 volts. The case is plastic and very sturdy with an integrated flat folding handle. This unit can be placed sidewards if needed as long as the vents are not blocked. This battery will not leak.For camping and portable power needs it is the right size. I have charged it with the includes device, and I am waiting for a new Amazon order for the 200 watt solar panel to test that method of charging. The output is limited to 750 watts which is more that enough for small appliances and devices. Anything over will trip its Internal breaker but by powering off and on again will reset it.So if you need up to 750 watts for a while or for a total of 550 watt-hours, the EB55 is the best for its price. Bluetti has been on the market for over ten years, and now offers large modular batteries (3 kwh) and controllers for home service, up to 6 kW for 220 VAC and add on batteries up to 24kwh, which can easily replace a gas generator for clean and quiet home power. Just add solar panels and this system will allow off-grid applications which is why I bought the AC300 system.
