BLUETTISolar Generator AC70, 768Wh LiFePO4 Battery Backup w/ 2 1,000W AC Outlets (Power Lifting 2,000W), 100W Type-C, for Road Trip, Off-grid, Power Outage (Solar Panel Optional)

Great quality/delivery time. Awesome Spring Sale price! Only complaint is I couldn't afford next level item up, or I'd of bought THAT! On the other hand, the sale afforded me to jump up to this level. Spent a little more than I could afford. But I'll get by. It was worth the investment. As advertised, it charged up super fast right out of the box on standard mode. from 54% to 100% in about 40 minutes. Played guitar on my Boss Katana 100 watt 2x12 cab with 5 9v pedals for about 8 hours straight, and it didn't put a major dent in the charge. Dropped to 59%. It indicated I was pulling apprx 30 watts AC. And could run it for 19.6 hours! All a great sign for my busking programs. I'm sure I can run my Mackie Freeplay Portable PA, looper pedal, and vocal processor no problem. The amp, and ALL of it for ATLEAST 8-10 hours by my calculations! My main worry for power pull was the amp. I was surprised at how little watt power it takes to run it. So I'm happy and satisfied with all that. It would've cost close to $300 to buy and run 2 new 12v outboard batteries with a new 400 watt inverter like I'd been doing for years BEFORE the pandemic! And that is such a lower level primitive way to go. And those batteries don't last long. So this is such a MAJOR upgrade for me in so many ways, for less than $50 more at the great Spring Sale price I was able to snab this AC70 up for. I'll be saving again and looking out for ANOTHER sale to eventually get 2 200 watt solar panels. I'm not only a musician, but also a car camper, survivalist and prepper. And this will meet my power needs in these regards. I'm not trying to power a hotel, cabin, big boat, or RV. I just need to have SOME reasonable, (for ME), emergency power as needed to survive somewhat comfortably if/when the SHTF! So this item covers A LOT of my needs all at once, at a great price and for 3,000 cycles of recharge potential? AND then at up to 80% AFTER THAT!? This SHOULD easily last the rest of my old life. And I would buy next level items of Bluetti's if chance allows. I'm amazed at the progress of technology in these products. Especially the Bluetti line. By all my research, they seem to be leading the field and setting the standard! I'm SO thankful I waited to invest in these advanced tech items, and DIDN'T get one of those dinosaur Jackery power stations back in the day! And at the prices they were selling them at too!? Gimme a break! They better get on board with the new LiFeP04 batteries if they want to STAY in the battery power station business! Just keeping it real Jackery and Jackery fans! LOL!

A great little power station/battery! Best for small or short high Watt loads, but very sensible and seems accurate. Noticeable fan noise when under heavy demand, so take it easy. Great seeing what my devices use/need on screen… and it delivers the bacon!Charged my Dr Prepare 100Amp hour battery from 50% to FULL via humble 100watt USB C (with power from a120v house plug). I bought the Bluetti “Charger 1” and a BougeRV 200watt solar panel so it will be happy!I look forward to VanLife with the humble AC70!

I bought this unit to be a UPS for a computer/TV workstation. The unit arrived on a stormy day. After I got it connected to AC and the computer/TV running on the inverter, the power went out, back on, out, on, out then on. The UPS function of the Bluetti AC70 worked perfectly. When fully charged, you are supposed to have over 700WH of power. That translates to 4-5 hours of operation on battery with my setup. If you are looking for camping power, this unit is light weight enough for one person to carry. You will have plenty of power for lights and charging cell phones. Probably not enough for cooking.

I am using as a back up power for my tv. Was forced to use the first weekend after receipt. Grid power was intermittent at first, then out for 2 days. Hooked up my generator and my Bluetti power informed me that it was inconsistent and smoothed it out for the tv. The power supply is really good because I could follow the tv weather reports and it gave me time, running the light and tv and internet modem, giving me time to set up my generator. I am very happy with my Bluetti AC70 power supply

I tested my unit with various AC loads on ECO mode. The unit would only produce ~460Wh rather than the specified 768Wh. This is a 60% reduction from stated capacity. For instance, starting at 100% charge, it would only power a 24W lightbulb for 19 hours rather than 32 hours expected from a 768 Wh supply.I will reach out to tech support as I may have simply received a defective unit. I suggest you test yours using a known load and recording the number of hours it powers that device. I will update my review if I find this was simply one defective device. Regardless, you should check your own before relying on it when you really need it.Updated: I confirmed from the manual that the BATTERY CAPACITY is 768Wh, but the unit's POWER DELIVERY CAPABILITY is actually the stated battery capacity times the efficiency of the system (85%) times 90% of the battery capacity (the unit will only allow the batteries to discharge down to 10% rather than 0%) minus 15w/h that the the unit itself consumes to function. Bluetti supplies this information (and formula) in the manual. So run time is calculated with the following formula: 768Wh x 85% (efficiency) x 90% (battery discharge range) - (15Wh + power required). The example they provide for a 40W fridge comes out to = (768 x 0.85 x 0.9) / (15 + 40) = 10.7h run time. So not the 768Wh/40W = 19.2h you might expect.To be fair to Bluetti, it's likely that most, if not all of the power station manufacturers are stating the battery capacity rather than the power station capability. Keep this in mind and set your expectations accordingly.I'm new to these battery power stations so this difference between expectations and reality may be obvious to experienced users. My knock with this Bluetti unit may be a bit harsh as this seems to be common practice across power station suppliers (advertising the unit's battery capacity rather than it's capability), so I increased my rating from 2 stars to 4 since other than this one shortcoming, this is an otherwise good unit. I do want to point out some other testing I performed with mostly positive results: The boost mode worked effectively. I was able to power a 1500W microwave and a 1500W heater with boost enabled. One minor drawback of that test was that the unit didn't display accurate power consumption up at those levels (it maxed out around 1200W). I'm not sure if that affected the battery % remaining, but it doesn't matter that much as the unit should only deliver 1500W for about 20-25 minutes. The good news is that it will indeed deliver up to 1500W which will power virtually all home appliances. The other measurement I monitored during my testing was power factor (which is a good indication of the quality of the a/c signal; it takes into account the distortion in the a/c waveform as well as the current and voltage phase difference). This unit consistently delivered a very high PF of ~0.99 out of a perfect 1.0 (this is very good).
