What devices can the power station charge?

The AC output port can only charge or power devices that operate at less than 300W. Incompatible with appliances that require more than 300W input such as microwave, electric grill, refrigerator, electric vehicle, air compressor, and more.

What kind of solar charger can charge this product?

Any 11-28V solar charger with a DC 7909 male connector.

How should I store and maintain the product?

1. To preserve the battery lifespan, recharge it to 100% after every use.

2. Turn on Power Saving Mode and turn off all the buttons on PowerHouse.

3. We recommend recharging it 100% every month.

What should I do before using for the first time and what do I need to pay attention to?

Charge your portable power station to activate the battery before using for the first time. Do not use with CPAP overnight and in Power Saving mode.

Why does the power station's battery drain even when no devices are connected?

When the AC and car socket control buttons are turned on, there will be a certain amount of no-load power consumption. To avoid this, make sure the control buttons are turned off, or turn on Power Saving mode when not in use.

Very cool little Power Station! (Anker 521 PowerHouse 256Wh)
5 Stars
Very cool little Power Station! (Anker 521 PowerHouse 256Wh)
I've unboxed and charged up my Anker 521 PowerHouse and it's pretty awesome. It's pretty light for what it is. Seems to be pretty sturdy as far as electronics go. I charged it up fully with the wall plug to 100% like it said to do. (likely to calibrate the battery management system so the battery % is accurate and the actual capacity is maximized) I powered a bunch of LED AC lights while charging my laptop, phone, a smaller anker powerbank, and some other devices plugged into the car power hole and it lasted for several hours. I feel like it actually lasted longer than I expected for not being a huge device. It will power LED lights for many hours. I bought some Ultra efficient 4 Watt Philips LED bulbs and it says it will power two lamps with those bulbs for over 16.2 hours at 90% State of Charge!! Great for power outages or for staying in off the grid Airbnbs which is what I bought this power station for. I saw another review that stated it draws power even when nothing is plugged in and after testing it I've found that isn't the case unless you have the AC outlet button turned on when you aren't using the AC outlets so it's a none issue. In case you are curious it said it was drawing 5W when there was nothing plugged in and the AC outlets were turned on but then when I plugged in two 4 Watt LED lamps it said it was putting out 10 Watts so it seems it's more efficient with a load but again you can use the other ports without having the AC outlets turned on and there's no extra draw. This is a none issue. It seems to charge up in the timeframe advertised with the wall plug charger but I haven't tried the dual plugs using that in combination with the USB-C plug on the front. If that doesn't work as advertised I'll update my review. I like the light on the front and handle on top but I do wish there was a carry case available for it. Maybe there is but it wasn't listed with it on the anker website so I'm assuming there isn't. The light on it is nice and the SOS feature is setup in a great way, I like that you just do a quick press to turn on and off the light and to activate the SOS mode you have to hold the button for 2 seconds so you don't have to cycle through either of those modes to get to the other. I would recommend this, it seems like it's pretty fool-proof and seems like it'll automatically shutoff if you try to charge it in damaging temperatures so it's pretty worry free as long as you don't store it with a low state of charge for long periods which can damage all Lithium based batteries.

I recently had the pleasure of using the Anker 521 Portable Power Station with the upgraded LiFePO4 battery, and I must say it's been an absolute game-changer. This portable power station has quickly become an indispensable part of my daily life, whether I'm on the go, camping, or dealing with unexpected power outages.

**Battery Capacity:** The 256Wh capacity of this power station is truly impressive. It's like having a compact powerhouse at your disposal. I've been able to charge my smartphones, laptops, and even run small appliances with ease. The peace of mind knowing that I have a reliable power source is invaluable.

**LiFePO4 Battery:** Anker's decision to upgrade to a LiFePO4 battery is a significant enhancement. LiFePO4 batteries are renowned for their durability and safety features. This upgrade ensures the power station's longevity, and I appreciate the added peace of mind it brings.

**Portability:** The compact design and integrated handle make it incredibly easy to carry this power station wherever I need it. Whether I'm taking it on a camping trip or simply moving it around the house during a blackout, its portability is a huge advantage.

**Multi-Port Design:** The inclusion of six ports is a lifesaver. I can charge multiple devices simultaneously, which is incredibly convenient. It's particularly useful when I'm traveling with family or friends, as we can all keep our devices powered up without any hassle.

**Build Quality:** Anker has a reputation for producing top-notch products, and this power station is no exception. It feels solid and well-constructed, giving me confidence in its reliability and durability for the long term.

**Applications:** The versatility of the Anker 521 is exceptional. From charging smartphones and laptops to powering small appliances and even some power tools, this power station handles it all. It's become an essential part of my emergency preparedness kit and outdoor adventures.

**Price:** While prices may vary, I believe the Anker 521 Portable Power Station offers excellent value for what it delivers. It's an investment that pays off in convenience and peace of mind, especially in situations where reliable power is essential.

In conclusion, the Anker 521 Portable Power Station with the upgraded LiFePO4 battery is a standout product. Its impressive battery capacity, durable build, and versatility make it a must-have for anyone on the move or looking to be prepared for emergencies. It's a reliable and efficient power source that has quickly become an integral part of my daily life. I can wholeheartedly recommend it to anyone in need of a dependable portable power solution.

Reviewed in the United States on February 12, 2024
My initial reasoning for this battery was to power my Traeger pellet grill / smoker. I was gifted the smoker a few years ago but we found we don't have any outlets outdoors. We would have to run an extension cord out the slider door into the kitchen for a few hours, so naturally we hadn't used it. I couldn't find any reviews that would suggest this battery would work for us, so I figured I'd write out my findings and hopefully it'll help out someone in a similar situation.

I read that the smoker uses about 300W for 4 minutes, then 50W after that. The page for this battery shows it can handle 300W, but I read further in the user manual and found that the AC ports only support 200W and would power off if they exceed that.
In powering on the smoker, the display showed it was pulling 257W initially and about 45W after a few minutes. I ran it for about 40 minutes as a test and the battery finished with 85% remaining.

This past Sunday I smoked some turkey sausages for 2 hours (plus 20 minutes for preheat and shutdown cycle) and the battery had 45% remaining at the end. The display said it could have kept going for about 2.5 hours. It lasts long enough for our uses (sausage, burgers, hot dogs, chicken), but for something like a brisket or ribs it probably won't last long enough.

I read the reviews on this, and yes, it does have some minor flaws, but none of these deterred me from buying. It has two AC outlets but only one can be a three-prong grounded cord. I have an adapter with three outlet plugs: problem solved. The USB-C connector is PD3 compliant, so my phone charges rapidly. The description of the Power Saving mode is not complete. Here is the response from Customer Service:

"For your information first: The power saving mode is mainly for the AC outlets and the car socket. It will not control the USB ports.
The AC outlets on the 521 Powerhouse will turn off automatically in power-saving mode when the output from the AC port is continuously less than 10W within an hour. So the threshold for "lower power" is less than 10W."

I like the display which shows power input or output in watts, the percentage of battery remaining, and the time to charge/discharge.

I bought this unit based on Anker's reputation and my satisfaction with many of its other products. My primary use will be to power my fiber gateway during power outages (a recent three-day outage prompted my purchase), but I'm sure it will be used often for other portable power needs.

5.0 out of 5 stars Best Stationary Battery Backup System
Reviewed in Canada on October 2, 2023
The station battery is designed perfectly. The recharging using USB-C is extremely fast. Make sure you have a 65W charging brick and a cable that allows you to do such fast charging. It's the original battery charing cord also charges fast, but not as fast. I charged from 50% to 100% only took 30 minutes. Output is also extremely fast.
