521 Portable Power Station Upgraded with LiFePO4 Battery, 256Wh 6-Port PowerHouse, 300W (Peak 600W) Solar Generator (Solar Panel Optional), 2 AC Outlets, 60W USB-C PD Output, Outdoor Generator

I bought this as an auxiliary power source for use in a vehicle--I need to carry a 12 volt refrigerator with me (special dietary needs, road food, etc.), and occasionally charge up Milwaukee tool or DSLR batteries even if the vehicle is not running. The packaging of the 521 is ideal, although I wish the two 120V outlets had "real" 3-prong outlets. The size is perfect when a vehicle is loaded up--it uses little space. I ran two tests with the refrigerator connected to the 12 volt outlet. The refrigerator operates in both ECO and MAX modes. The ECO mode draws 30-35 watts while operating, while the MAX runs at anywhere from 40-50 watts. I ran the refrigerator indoors somewhat near a heat outlet, to simulate being inside a warm vehicle. The refrigerator is rated to deliver 256Wh of power, so I calculated that worst case would be the refrigerator running constantly for 5.5 hours. Turns out that with the refrigerator cycling on and off, it ran over 20 hours before the battery was down to about 2-4% capacity. EDIT: I had a charging issue that was partly my own misunderstanding and partly my car's wiring. I was at first unsuccessful in getting the 521 to charge from both inputs. First, I had to use a USB-C PD charger, which provides higher voltages than standard USB chargers. This allowed a full 65 watts on the USB-C input for charging. But I would add the 120 volt charger that came with the 521 in tandem with the USB-C charger wasn't getting the ~120 watts of charging. I later realized that for battery health, the 120 watt charging through both DC inputs only happens when the battery's state of charge is lower. If it's nearly fully charged, it cuts back to only a single DC input. Yet, I still could not get both to work in the car. I have a 150 watt 120-volt inverter in the car, which plugs into a rear accessory outlet using a lighter plug. It turns out that if I have both the 521's 120 volt charger and a USB-C PD charger plugged into the inverter, the inverter stops working. Likewise, if I use a separate USB-C charger that plugs into the accessory outlet (I have a 1:3 adapter with a voltage readout), the inverter cuts out. It seems the inverter is cutting out when voltage drops below a nominal value like 12.8 volts. In essence, the wiring from the fuse box to the accessory outlet cannot provide full wattage without voltage sag. When I plug the USB-C PD adapter into an accessory outlet in the center console (which is on its own 15 amp circuit), I can get 120 watts of charging to the 521. I will wire up my own circuit with 6-gauge wire to run a 300 or 400 watt inverter and a pair of accessory outlets, as this will eliminate the voltage drop. With ~120 watts, this provides a quicker recovery for the battery while the refrigerator is operating, which is exactly what I needed.

Dateline: A Silent House, 1:25 AM. The power is out. The grid, that fragile, humming web we all depend on, has finally given up the ghost. The neighborhood is plunged into a sudden, medieval darkness. The silence is deafening, broken only by the frantic, internal monologue of a man whose digital nervous system has just been severed. The phone is dying. The laptop is a useless brick. The world has shrunk to the size of a single, dark room. This is the moment of truth. The moment that separates the prepared from the pathetic. And in my corner, sits a quiet, unassuming grey and black box: the Anker 521 Portable Power Station. This is not a generator. A generator is a loud, stinking, gas-guzzling beast that screams your desperation to the entire county. No, this is something else entirely. This is a silent, solid-state brick of pure, unadulterated electric potential. At its heart is a LiFePO4 battery, a name that sounds like a mineral mined on a hostile moon. And it has the constitution to match. This isn't the fragile, temperamental battery chemistry of a cheap power bank. This is the hardened, long-haul stuff, built for a decade of abuse and a thousand cycles of life and death. It’s the kind of reliable core you want when the lights go out for real. You press the button, and the little screen glows to life, a calm, rational display of numbers in a world gone mad. It tells you how much juice you have left, a beautiful, concrete percentage of hope. And then you see the ports. It’s a beautiful, multi-pronged solution to the problem of a dead world. Two proper AC outlets, the kind you find in a wall, ready to accept a lamp or a laptop charger. A 60W USB-C port that funnels power into a dying MacBook with the ferocity of a firehose. A whole suite of USB-A ports for the lesser-but-still-vital gear. The phone gets plugged in. The smartwatch. The rechargeable lantern. The laptop. One by one, their tiny charging lights blink on, small constellations of defiance against the oppressive darkness. The house is still black, but my little corner of it is alive. I have a communications hub. I have light. I have a connection to the world outside my unlit window. I’ve dragged this box into the wilderness, a willing companion on camping trips where it kept the music playing and the cameras charged, a silent workhorse in the middle of nowhere. It has weathered every storm, both literal and figurative. The Anker 521 is more than a battery. It’s a plan. It's a small, portable declaration of independence from a fickle and unreliable power grid. It’s the quiet confidence of knowing that when everything else goes dark, you have a 256 watt-hour box of pure, life-giving electricity, waiting patiently to be unleashed. It’s not just a power station; it’s a peace of mind you can carry by a handle.

I bought this for frequent trips to the Everglades. It works amazing. You can get about 15 phone charges out of it. I can charge all three batteries on my dji air3s from dead to full once. It can run multiple things at once and shows your current output. Has a built in light that is easy to use. The outlet and car port must be turned on manually. I did try to overload the battery and it auto shut off. Battery can be charged in about an hour and seems to hold a full charge well (no leakage). You will hear the fan turn on but it’s not loud at all. I paid $130 on sell and I’m very happy with it Hand for size

J'ai commandé ce produit dans le but de gonfler mon paddleboard soit par prise classique soit avec une prise 12 volts et ça fonctionne très bien. De plus la lumière est très pratique le soir. Je m'en suis servi depuis à d'autres occasions et c'est vraiment parfait et le transport est très facile.

I bring this with me when doing craft shows and camping and it’s way better than carrying around a bunch of power banks. Recharged multiple devices multiple times and still had juice left over. Only thing it hasn’t been able to power was a small home printer.

This was gifted to my son for power failures. He said that it charged up easily. He has yet to be able to use it for power failures.

I found this works excellent and as advertised. I purchased this shortly after a power outage caused by an ice storm here in Ontario Canada and have given it a full test on how well it charges, works for charging and powering other devices finding it does what I need for the most part. Great item for camping or keeping things like cell phones and laptops running as well as providing a light during emergencies at home or while away.
