Portable Power Station 1000W, 1228WH Capacity LiFePO4 Battery, Support Up to 15 Device, Power Equipment, Solar Generator Charge 0-90% In 2 Hours, Backup Battery Power Supply Kit for Outdoors, Camping, Travel, Off-Grid, Emergency by VCUTECH

I live in California and the number of rolling blackouts we have been having just keeps on increasing due to the progressive’s insistence on unreliable “green energy” sources. Sometimes it’s just a couple of minutes and other times its 8-9 hours. So, I started to look into power banks for backup to keep my fridge going and to have some light.After much research and looking at as many different brands as I could, I came up with a list of things that I wanted in my power bank:1. LiFePO4 batteries (more charging cycles and much more stable than Lithium Ion).2. At least 1,000Wh of storage capacity (which could power my fridge for about 10 hours).3. Quick charging via AC.4. Capable of being charged via solar.5. At least 1000 watts of output (enough to power my fridge and a couple of lights with plenty to spare).6. No fancy touchscreen or WIFI and Bluetooth Apps (less to breakdown and malfunction).After searching Amazon and looking at all the major name brands I came across the VCUTECH unit and it checked all the boxes of everything I was looking for, so I decided to order it. Big mistake!It was well packaged and not that heavy at 34 Lbs., looked and felt solid, and was very easy to operate with only 4 buttons to turn things on or off and the manual was easy to read and understand. When I received it, it was fully charged at 100% so I started testing it within minutes.Here is a breakdown of how I tested it:Test 1:A 20-inch fan drawing 135 watts. The unit showed 53% battery remaining at the 4 hour and 20-minute mark then beeped several times and shut down. When I plugged it in to charge it showed 0% battery. So total output was about 535Wh. Charging it to 100% via AC took a bit over 2 hours.Test 2:A 20-inch fan drawing 135 watts. The unit showed 19% battery remaining at the 6 hour and 57-minute mark then beeped several times and shut down. When I plugged it in to charge it showed 0% battery. So total output was about 951Wh. Charging it to 100% via AC took a bit over 2 hours.Test 3:Two 20-inch fans, two table lamps with LED bulbs, an air purifier, and a tower fan drawing a combined 266 watts. The unit showed 19% battery remaining at the 2 hour and 32-minute mark then beeped several times and shut down. When I plugged it in to charge it showed 0% battery. So total output was about 665Wh. Charging it to 100% via AC took a bit over 2 hours.Test 4:A 20-inch fan and an air purifier drawing a combined 191 watts. The unit showed 1% battery remaining at the 5 hour and 13-minute mark then beeped several times and shut down. When I plugged it in to charge it showed 0% battery. So total output was about 991Wh. This is one of the times it actually ran all the way to 0, but is about 300Wh less than the advertised capacity. Charging it to 100% via AC took a bit over 2 hours.Test 5:Two 20-inch fans and an air purifier drawing a combined 238 watts. The unit showed 21% battery remaining at the 3 hour and 47-minute mark then beeped several times and shut down. When I plugged it in to charge it showed 0% battery. So total output was about 900Wh. Charging it to 100% via AC took a bit over 2 hours.Test 6:An air purifier drawing 47 watts. The unit showed 57% battery remaining at the 10 hour and 28-minute mark then beeped several times and shut down. When I plugged it in to charge it showed 0% battery. So total output was about 491Wh.Test 7:A portable halogen work light and 20-inch fan drawing a combined 334 watts. It showed 1% battery remaining at the 3 hour and 3-minute mark then beeped several times and shut down. When I plugged it in to charge it showed 0% battery. So total output was about 1,000Wh. This is only the 2nd time it actually ran all the way to 0, and gave the highest Wh, but is about 228Wh less than the advertised capacity. It would be fine if it always ran like this but it doesn’t.After these first 7 tests I noticed a strange trend. That the less power you were using the less you would get out of it, there were a couple of times where this didn’t apply, but for the most part that was the case. So I decided to do one more test with very little power draw.Test 8:A small table lamp with an LED light bulb drawing 4 watts. It showed 94% battery remaining at the 42 hour and 15-minute mark then beeped several times and shut down. When I plugged it in to charge it showed 0% battery. So total output was about 168Wh.As you can see it shuts off randomly anywhere from the 19% to 94% battery remaining mark still showing depending on how much power you're pulling out of it. This is unacceptable from a device used in emergency situations. How on earth can it go from 19%-94% to 0% in the span of seconds? It’s too bad because it’s really a nicely built unit and charges up quickly via AC.Don’t believe the positive reviews on this item as they fall into 2 categories, those that didn’t test it thoroughly and those that are outright lying. I’ll give you an example: The top review says, “I was able to plug several devices into this Power Station while running all of them at the same time, (with about a 110-Watt load total) and continue to use them for over 11 hours before recharging was needed,”. Well, this can only happen in 1 of 2 ways. 1, Either the laws of physics, especially Ohms Law, no longer function where he lives, or 2, he’s lying. I’ll go with number 2 and can prove it. A 110-Watt load for 11 hours means he managed to get 1210Wh out of a unit that only has a capacity of 1228Wh. This would mean that this unit has an inverter efficiency rate of 98.53%. This is unheard of, considering that the best inverters are usually between 85%-90%. Also, the inverter on these gets much worse with lighter loads. I’ll point you to the results I got from Test 7 and 8. Test 8 had a relatively light load and I only managed to get 168Wh out of it, for an efficiency of only 14%. While test 7 had the highest load and I got only 1,000Wh out of it, for an efficiency of 81%. This inverter was designed for higher loads at the expense of lighter loads or has something seriously wrong with it. In short, the inverter uses a lot of power which isn’t taken into account by the controller. There may be an issue with the controller also that’s why it shuts off randomly, since the power used by the inverter isn’t calculated into the remaining battery % or time and explains why the “battery lock” icon turns on every time and it just shuts off with lots of time and power still showing.So, after all my testing and getting nowhere near the output claimed and it shutting off randomly, I emailed the seller and for 3 days no response. So, I tried the chat function on their web site only to receive a “No one is available to answer your question at the moment” message but submitted my concern anyway. I then tried calling them via the number on their web site and no one picked up. That’s when I started to worry that I just may have lost $900.I contacted Amazon customer support and explained my situation with this faulty unit and they were very apologetic and asked me to hold for a bit while they checked something. I can only assume that they attempted to contact the seller and when they couldn’t they corrected the issue immediately by refunding me my money. Kudos to Amazon and their support personnel for fixing my situation. So, then I tossed the thing in the car and dropped it off at the E-waste center. I don’t need some defective unit that can catch on fire in my home.I said it’s defective and can prove it. About three hours After contacting Amazon the seller contacted me with the following message:“Hi XXXXXXX,We are sorry to hear this from you. Yes, we have noticed the inverter issue and we have just noticed the manufacturer one weeks ago.The manufacturer has agreed to send us the replacement parts for this item. Unfortunately, they will not be here in 2 months.At this point, we can certainly issue you a full refund for this item. The return label is attached.At last, we kindly ask if you could withdraw the product review on Amazon since we have just start selling this item for less than half year. This is our first item in this category.Best--XXXX | VCUTECH Support Team…..”Well, VCUTECH, I hope you enjoy my new review and shame on you for trying to continue to sell a defective product by trying to get me to remove my review. Now I don’t feel so bad for throwing the POS away and for the money you may have lost.Also, after doing a bit more searching, I found this exact same item being sold under two other different name brands. One is labelled “iFORWAY” and the other is labeled “VDL”. However, the “VDL” one is no longer available, they must have pulled it after realizing the problems this would cause. I even downloaded the manuals for both and the instructions are identical, even though the layout is a bit different. So, what VCUTECH is doing is buying cheap Chinese garbage and labeling it as their own.

I was in love with this product and purchase. It seemed to work perfectly and do everything that it advertised to be able to do.One day, I was charging the box with the solar panel that it came with, and we we’re getting lots of sun. I was using the box to power my router, so I thought I would leave the solar panel connected, considering a conversation with the sales person said it was okay to leave the solar panel plugged in at full charge and that there was an internal mechanism that would prevent overcharging.Everything seemed fine until the next day, when I was working remotely, and the low battery alarm went off and the box shut down. I was 3 hrs into my work day, powering my router and computer. Before that day, I could get in two full 8-hr work days without having to charge the box. I can only imagine that I’ve damaged the box by overcharging. If that’s not what happened, then the box only lasted a few weeks at full capacity, which seems worse.I’ll be contacting the sales team to see if there’s anything that can be done. For now, this should serve as a warning to those charging by solar (and maybe because something was also plugged in?). To be fair, I’m still not 100% sure that’s what happened, but I can’t think of any other reason why the capacity has plummeted, especially considering the timing of the events.

When you consider the significantly greater life expectancy and the safety aspects of using a LiFePO4 battery Power Station, versus those with the typical Lithium batteries, these features alone make this an exceptional value. And the A/C outlets on this unit can also be utilized as a UPS, I tried it and it works!I was able to plug several devices into this Power Station while running all of them at the same time, (with about a 110 Watt load total) and continue to use them for over 11 hours before recharging was needed, which is one of the great features of the high Watt-Hour capacity of this Power Station.I let the devices that I was using continue to run until it took the battery down to 1 percent and then, using the wall outlet with just the A/C cord as a converter brick is not needed, it fully recharged to 100% of capacity in less than 2 hours of charging! I have purchased several other Portable Power Stations however, none came close to the recharge rate of this VCUTECH Delta 1000W/1228WH Power Station.Most importantly to me, their Customer Service has answered their phone every time I have called them and they also took the time to respond to a every question I had over a period of several weeks when I was comparing the features of several of the 1000+ Watt Power Stations before I purchased this unit.The VCUTECH Delta 1000W Power Station is a great value for the price point and I highly recommend it!

The power station is well packed and it works as expected. I really like quick wall AC charge time.I will mainly use it when there's a power outage. It's heavier than my Jackery 1000. Overall, the unit seems well designed and well built. Hope it will last a long time.

Product is very easy to use.

I received the power station on Dec 05, 2022, at 10 am. I immediately started to use it, and after 3 hours, it went from 60% to 0% battery charge in seconds and suddenly turned off.I requested a refund, and I'm still waiting for it. I've been trying to reach VCUTECH customer support with no luck; they don't answer emails. I let Amazon know about it. DON'T BUY THIS!

It last three nights with you babe and it does not lose power while serving on like bluetti

This is a great budget product and the customer service is outstanding
