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

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 :)

This is very useful power station for small electrical devices while having a weekend camping break. Or about the house. The solar panels are also excellent. They come with the usual box of adapters that plug straight into the 521 unit. The adapter a DC 7909 plugs into the station and has the female connection a yellow XT60 at the other end. It jacks to a male XT60 connection where it has the connectors for the 2 MC4 to the panels. Simple

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.

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.

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
