Original: After about 10 uses, no ports output power. The only thing that works is the flashlight, the LCD display, and you charging port on the back.
Pros
• Its size is ideal, and it’s super portable, so I could easily take it with me on my next camping trip.
• The battery capacity is perfect for keeping my laptop running and charging phones. It has also been useful for powering fans, lamps, and even the TV.
• The ports allow multiple devices to charge simultaneously, and the screen displays the estimated remaining runtime.
• One feature I didn’t initially pay attention to is the built-in light, which has been handy for placing it on the nightstand during power outages.
Cons
• It would be a great addition to have an app to monitor energy consumption per outlet.
Overall, I’ve had an excellent experience, and although Anker can be a bit pricier than other brands, the quality of their products is worth it. I’d even consider buying a higher-capacity power station if needed.
256Wh capacity and 300W output is perfect to power some lights around the campsite when it gets dark, charge phones at night for the next day and fill up an air mattress.
Now do I expect it to power a kettle or a coffee maker? No, but that was not my intentions when purchasing this power station, just enough power to bridge the gap but not too much power to "ruin" the tent camping experience.
Personally I opted for a 50W panel and it pairs nicely for the intentions I had for this set up.
Love the built in flashlight/lantern, and the size is perfect for camping or carrying about.
So I really needed a lightweight, portable, but durable and reliable battery that can power my gear. In context, I’ve experience with a Jackery borrowed from a friend. This Anker power station is an upgrade to me, with an extra USB-C port and a bunch of other add-ons. It fits in my pack and doesn’t add a crazy amount of weight. The handle is comfortable in my hand and makes carrying it easy. Once I set up camp, it’s easy to use. Probably my biggest requirement was being able to charge multiple batteries at once, my drone’s spare battery charger, my DSLR, phone, galaxy buds.
A major factor in my choosing the Anker 521 was its USB-C port. A while back I borrowed my friend’s Jackery which ended up being dead weight in my pack because it doesn’t have a USB-C. I didn’t bring any adapter as I expected the power station to have a C port for charging laptops and drones. So I paid special attention before placing the order. This Anker station has the USB-C built-in, also 2 AC ports to support both my camping light and one other device at the same time - another plus over my friend’s Jackery.
One thing to note is the build quality on this thing. I had set up camp in a nook by some ledges beside a cliff and had put the Anker 521 on a boulder. I camp with my dog, who is a complete spaz, and he was sprinting around and knocked which caused it to slide off and fall maybe 3-4 feet onto solid rock. After inspection there wasn’t any visible damage and it still worked completely fine.
In sum, the Anker 521 is excellent if you need a power station that is:
Lightweight
Has USB-C
Can charge multiple devices at once
Super durable
Sleek design. Easy to use.
