Anker 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 GeneratorClimatePartner certified

Really easy to use and it comes with a 5-year warranty, which is a great bonus. The overall quality is solid—it feels durable and looks really sleek. The light is surprisingly bright, and I love that it includes an energy saver button. The solar kit is a bit pricey, so we’ll have to save up for that part, but it’s definitely worth considering down the line. Overall, a great product and I’d highly recommend it!

I was very impressed with the product. I paired this with a 100W solar panel and was able to run a JBL Partybox 110 at full blast all day at the beach and the Power station remained at 99-100% all day. It is very high quality and I would definitely recommend.

It came with AC adapters only overall good enough for my device I'm using little things that keep me charging my cell phone and USB fans for week good for emergency or camping

The Anker 521 Portable Power Station is hands down one of the most reliable and versatile tech investments I’ve made in a while. Whether you're prepping for unexpected outages or planning a weekend of camping, this unit delivers exactly what you need—and then some.⚡ What Makes It Great:Built to Last: With InfiniPower technology and LiFePO4 batteries, this thing is made for longevity. Knowing it’s built to last over a decade with daily use gives me peace of mind. You can feel the quality in the build too—it’s rugged, impact-resistant, and clearly designed for the long haul.Perfect for Weekend Trips: The 256Wh capacity is ideal for recharging phones, tablets, portable lights, and even a mini fan or camera setup. I took it on a two-day trip and still had juice to spare.USB-C Port is a Game Changer: The 60W PD USB-C port means no more bulky adapters for your laptop or other devices. Just plug and go. I use it for both my MacBook and my Switch—no problems whatsoever.SurgePower Up to 600W: This was a pleasant surprise. The 300W rating with 600W peak support let me power a mini-fridge and an electric kettle (separately, of course) without issue.6-Port Convenience: The mix of 2 AC ports, 2 USB-A, 1 USB-C, and a car outlet makes this incredibly versatile. Whether I’m charging a phone, running lights, or plugging in my camera gear, I’ve got plenty of options.🔋 Final Thoughts:If you’re looking for a true energy backup solution that’s also perfect for travel, camping, or emergencies, this is it.

I got this with a solar panel to go with it. And it is an amazing portable power station. My phone is charged in no time, and I can go for days without recharging the power station! Love this product

Great product lasted all weekend camping

Buggy and doesn't match expected capacity...Already owning a Jackery 240, I chose this for my second power supply of this size because of its LiFEPO batteries and nifty front facing light, with the understanding it would be a little bigger and heavier due to battery chemistry but also have an extra 16 watt hours of power and all the safety/endurability improvements of that battery chemistry. After all, LiFE batteries last for several times as many charge/discharge cycles as standard lithium ion (like in the Jackery 240) and are more heat tolerant before they enter into a runaway reaction (i.e. overheat and spontaneously combust).It's way too early to confirm that this battery system can manage the 3,000 cycles that Anker claims and most other manufacturers only claim 2,500 cycles for theirs, but I like the warm white front facing LED lamp and still hope the unit will last a long time. I also hope that it's as durable as they claim, as that was another selling point. This is where my positive impressions end, unfortunately.Another task for this unit was to replace the Jackery 160 that I'd kept by my desk with my internet router and PC monitor plugged into it, serving as a UPS (uninterruptable power supply) so that short blackouts wouldn't disrupt my working remotely from home. For one of these units to do this they must have "pass through" charging, meaning that they can simultaneously charge or keep their internal batteries topped up while also powering whatever's plugged into them. Some lesser/older models don't have this feature, so if you use them to power something and then plug them in to recharge themselves, they'll shut off the power to whatever's plugged into them. Pass through is great for having instant backup power and/or using them to power things during rolling blackouts, as they can charge themselves during the periods when the power is on without you having to intervene. This provides much better peace of mind when you're using the device to run something critical in a power outage rather than just out camping.My two Jackerys work great for this and so does a Bluetti I also own. But with the Anker, regardless of whether I set power saving or "eco mode" on or off, it would cut the inverter intermittently when left plugged in. It does this to things powered via USB as well only, because there's no on/off for the USB outputs, they resume receiving power after a moment's pause. I thought I'd received a bad unit and returned it for a new one but the replacement behaves identically. And speaking of plugging it in, compared to the other portable power stations I own, this one's transformer is on the plug itself, gets quite hot and uses a thinner gauge cable between itself and the unit. Cheap.FYI: The input barrel plug is the same size as the ones for the Bluetti EB70S and Jackery 160 and 240 units.Still on that topic, you can indeed charge the Anker via both its charger and a USB-C cable, simultaneously. Using my iPad charger I managed to push the 62 watts from the AC adapter up to 77 combined. A more powerful USB-C charger pushed this over 100 watts. But one of the advantages of the LiFE chemistry is that it can charge faster, so why the cheap power supply that outputs the same as the Jackery 240 with its inferior battery chemistry in the first place? The up side of this is that you can charge it via USB-C if you lose the AC adapter or use a solar panel with only USB outputs.Finally, the capacity. It's bigger and heavier than the Jackery 240 and boasts 256 watt hours of capacity to the Jackery's 240 wh. Yet with them both fully charged and then used to power window fans drawing 49 watts each, why was the Anker showing 61% battery remaining when the Jackery was reporting 72% left? I guess that doesn't necessarily mean that they're lying about the unit's capacity, but if they're not then the inverter is definitely significantly less efficient in the Anker -- And if that's the case, why does it read the same outgoing wattage?So to wrap up: Compared to a $30 less expensive Jackery 240 with older battery tech it's bigger and heavier and doesn't work properly as a UPS. It claims to have over 6% greater battery capacity yet actually revealed itself to be 15% its lesser. With LiFE cells rated at 2,500 full charge/discharge cycles before they drop to 80% capacity vs. standard lithium ion batteries only having 500, I suppose they'll be capacity equals in 500-700ish full cycles.Son, I am disappoint.UPDATE 2022.12.29: A new fun thing about this is that it also now shows 100% for around half of a discharge cycle, then increments down to a bit below 50%, then suddenly cuts power and reports a flashing 1% remaining. Charging with both inputs it prematurely disables the USB input and shows 99% for a large portion of the charge cycle while the AC charging brick flirts with 160 F temps. They really just don't seem to have implemented anything properly and at this point I regret the purchase and have dropped my rating to one star -- And that's having paid less than what it's going for now, now that the $50 coupon is no longer available.UPDATE 2025.04.05 Aaaaand...It's dead. I've probably cycled this 100 times over the last few years, and today it continually tells me it has 100% battery but then flashes 1% when I try to use the power. Plugging a USB C cable in to charge it, it refuses to accept the charge because it apparently thinks it's fully charged already. The reset button on the back didn't do anything to remedy the situation.The battery cells may support 3,000 cycles, but the electronics sure don't. Fortunately, I still have the Bluetti power station that I mentioned in my first review. It's seen more usage than the Anker and works flawlessly to this day.
