Anker SOLIX 521 Portable Power Station, 256Wh/200W LiFePO4 Battery Generator with AC Outlet, 60W USB-C PD, LED Light for Camping & RV

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 :)

Very handy, small compact and works amazingly well. Great quality and value for money

Early days as only just received this.. Came partly charged at 85% so i plugged in to give full charge.. Main use is for a portable guitar speaker ( no tested as yet) The other was to run a Sunster toolbox diesel heater to take camping. The heater draws 10-12 amps on start up then drops to a lower drain. Pleased to say the Anker ran the Sunster 12amp mains power supply ok and very handy to see the wattage display (123w), minor drawback it that the display goes dim very quickly. Not ideal when you are trying to test something but can see why they set it like that to save power. Otherwise very pleased.

Pros: ✅ Lightweight ✅ Easy to carry ✅ Decent capacity for the price ✅ Very clear display that shows lots of useful info Cons: 🛑 Needs a couple of other USB C ports 🛑 The light isn't dimmable This is a great unit, has all the basic ports (though probably needs another/more USB C, and has a whole bunch of charging options too. You can charge using the DC port, on the back or the USB C port in the front, in fact you can use both simultaneously to double the speed. It has a UK 3 pin plus to DC wire, and also a car 12v to DC connector. Solar panels will also typically plug into this DC connector. It's a relatively standard DC pin size, but as one reviewer states negatively "Why is it proprietary?" - well, firstly it's not proprietary, and secondly the reason is doesn't use a kettle/clover/figure 8 cord like a lot of other appliances are because these are AC connections, and the unit is a DC unit. Any AC power will need to convert to DC to charge the batteries. This is done usually with with a transformer on the plug (as with the supplied one), or half way along the cable (as per a lot of laptops with the power 'brick'), or have it added internally inside the unit itself which adds weight, bulk, and heat to the unit making it less portable. It's a non issue, and even if it were the USBC charges almost exactly the same speed as the DC port, and that's "standard" (if you have a suitable decent USB power supply..) It is rated at 256wh (Watt Hours), meaning you can theoretically supply 256 watts for an hour... (theoretically, as a) they are never that accurate, and b) there is a 200w limit). This may seem obvious to some, but not everyone understands electricity and thus might be confused about what to expect. 256wh is the same as 128w for 2 hours, 64w for 4 hours etc etc.... The display shows the current output, and an estimation of how long it can continue to provide the current output. So if you are running a cool box, or lighting etc and it is showing 25w output, then you know it should last about 10 hours. Similarly, it also shows the charging input speeds - less useful when plugged into the mains, great for seeing what your solar panel is generating - As DC charging is limited to 65w, don;t get a 65w solar panel, get a 100w or more if you intend to use Solar, these things only produce the stated wattage in ideal conditions, so you'll want to have a panel that can produce 50-60w reliably in less ideal conditions, rather than a 60w one that will only produce 20-30 on overcast days for example. It has a light but it has no adjustment, just on, off, or flashing... - might be too bright for ambient lighting in a small space, which is a shame as it's a nice warm tone. The handle is permanent and not folding, so super sturdy.

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.

It is what I expected

Did not charge anymore. Do not buy

It stopped working for me after a few months, and the light doesn’t turn off and none of the buttons are functioning
