Anker 521 Portable Power Station Upgraded with LiFePO4 Battery, 256Wh 5-Port PowerHouse, 300W (Peak 600W) Solar Generator (Solar Panel Optional), 2 AC Outlets, 60W USB-C PD Output, Outdoor Generator

My review is more of a 4.5 / 5. The unit functions very well, charges either through the provided charger, USB C Power delivery in the front, or any other DC power into the port in the back (never really shown in reviews). It also seems to be able to charge and power items at the same time, which some other battery banks cannot do. The light bar on the front is not the best, but it is an extremely warm white, which makes it comfortable to look at.Similar, I have a picture of the details of the charger, as i have never seen any information about this.The Anker 521 also fits perfectly inside a certain popular brand compressor 12L car fridge, which was also powered for at least 8 hours with the Anker.The drawbacks? If you have something plugged into the 12V car lighter port, the rubber cover gets in the way of the power button for turning that port on and off, and that 12V port has no "locking" tabs inside. The power buttons (though slightly concave) are just a single light touch from turning things on and off. the "screen on" button and the "DC power on/off" button are very close, and in the first few weeks of using it i would get them mixed up. And even more minor, the provided charger is a little bit bulky, and a little bit slow, charging the device in a few hours. Not a concern for me.

Update (October 2023) - After more than a year using this great little power station it is still working perfectly and providing the same level of performance. Compared to some models it is super portable, which means I am more inclined to take it with me on my travels. Recently I have been using it to power a 5G home router and my laptop, creating a truly portable office!Original Review:Having waited for this Power Station to be on offer, I grabbed it while 15% off.The idea behind this purchase is to use it as a backup to power my Indel B TB15 fridge in my campervan, as well as the ability to charge mobile devices when out and about.Test 1 - Powering an Indel B TB15 fridge at 3 degrees.After charging the battery to 100%, this little power station managed to power total of 26 hours before reaching 1%. While not a scientific test, this should comfortably provide power for up to 24 hours for a small compressor fridge. Power consumption is 30-31W, but of course the compressor only operates intermittently.Test 2 - Fastest Recharge to 100%.For this test, I used the supplied 60W power adapter and a 65W USB-C power supply. Result: The battery charged from 1% to 100% in under 2.5 hours.I will update this review with further tests, but so far I can highly recommend the Anker power station, especially with the 5 year warranty!I hope you found this review helpful :)

I really like this product.It charges fast, holds the charge without self-discharging, and has great features for the money/size.I bought this as I work from home and was having some work done on my house so the power would be cut off randomly. I used this like a UPS (uninteruptable power supply) for my 34 inch 4k screen attached to my pc (using the mains power plug). The battery could keep the screen on (bright) for about 7-8 hours. It got me through the work period with my hardly noticing the mains power outages. Even the light was useful as the office is quite dark with the mains off.I used it on another occaision as backup power for my broadband router, and this only draw a negre current so the life would be huge but the router is under my TV and despite the mains being on, and the battery already fully charged, the fan would occaisionally come on. This was slightly annoying when watching tv but hideously annoying of the TV was off and I was taking a nap on the couch. The unit isn't hot when this happens. In fact, it seems quite cold. This is the only gripe though, as apart from the the unit does exactly as stated. It provides a good amount of power and versatility and if you use a GAN charger as well as the standard charger that comes with it, it charges in no time at all.Actually, I do have one more gripe. Not enough USB-C ports. It only has one! Given the sixe of the unit, 2 or 3 should be the minimum. It has two USB-A 3 ports, but I don't have any USB-A devices anymore.

I've used this regularly for 9 months. Have taken it everywhere camping, road trips, days out and it's been spot on however this last couple of weeks it's been playing up the display doesn't accurately show what charge there is left it stays at 82% for quite some time then just zero dead nada and it might have charged a phone 3-4 times when it used to charge it around 15 times great for the 4 of us. I have asked for assistance on the issue and support has responded but they won't provide a return label they want recorded delivery and it's hardly a light item it's also a battery which is an additional cost I feel a pre paid return label should be the minimum requirement for a company of this size. Not sure how long this item should last but I would have thought years not month's anyway long story short I would avoid Anker but a jackery I have a jackery that is older but is much better it's just a little too big for short trips hence the reason for this purchase.
