   Great product so far!
   I’ve only used it a few times so far, but this Anker has exceeded my expectations. I use it for music performances and it powers my instrument, my laptop, and my amp all at once so I can perform anywhere.

   Before buying the Anker 522, I tried the Bluetti AC2A and the EcoFlow River 2. All three use LiFePO4 batteries, but there are some key differences.
   They’re all very compact and lightweight, and the biggest difference physically is the handles. Anker’s sticks out of the top, EcoFlow’s sticks out the back, and Bluetti’s is off of the top-back corner. This makes the Bluetti the easiest to fit into your car’s trunk, but the Anker the easiest to carry.
   Where capacity is concerned, the Anker 522 has 299Wh, the EcoFlow River 2 has 256Wh, and the Bluetti AC2A has 204Wh. Bluetti also offers the EB3A with 268Wh, but it’s heavier and more expensive than the other three units.
   Only the Anker has a built-in light bar, and it’s the only one without an app. This means that all of the controls are relatively basic. The apps for the other two allow you to monitor status, download firmware, and see how energy is flowing in and out. However, this also means that they’re also consuming power for their Bluetooth/WiFi radios. It’s not much, but it still depletes the battery over time.
   The Anker recharges through a dedicated input on the back, using a separate AC power supply or an included car-charging cable. In contrast, the other two have their power supplies built in. There are positives and negatives to both approaches. The Anker’s power supply is another thing to carry around…but you can leave it in the car when you know you don’t need it (e.g. at the beach).
   The external power supply also makes the 522 the slowest to recharge from AC, at a maximum 120W (24V/5A). Since the other two have their AC inverters built in, they can adjust the charging speed to go much faster. However, the faster you charge them, the more the fans have to run to keep their electronics cool. The EcoFlow is the loudest by far, while the Bluetti can be adjusted to prioritize noise or speed. Meanwhile, the Anker is completely silent when charging.
   There are only three on/off buttons on the Anker 522 for the display, car socket, and AC outlets, as well as a toggle switch for power-saving mode (which turns the unit off after a few hours). I like that the buttons are all inset (instead of protruding), so that they’re less likely to be pressed accidentally. I also like that the rubber cover for the car socket is hinged, so the you can’t lose it (the EcoFlow’s is not).
   In a pinch, you can also recharge the Anker and Ecoflow using their USB-C ports at a maximum 60W.
   After using all three, I think the Anker 522 offers the most bang for the buck and I appreciate its quiet recharging. If you absolutely need to be able to recharge in a hurry, one of the other two will suit you better. But really, how often do you need to do that?

   Although the refurbished meant it wasn’t at it’s original capacity, for the price you can’t get better, and it’s still Anker quality. Using it often while the 90 day renewed guarantee lasts
   Calculations below
   299wh new
   Excellent refurbish>80%
   >240Wh
   At 99% full charge
   296wh (supposed original)
   With load drawing 135w
   In theory, 2.2 hrs based on original
   Unit estimates 1.4hrs
   63% original 299wh
   Started 9:17 (ETA 10:41)
   Translates to 189wh estimate
   Actual 9:17-10:45
   =1.47hrs
   X135w = 198.45wh
   =67% original
   Outdoors at minus 5 Celsius
   1.5hrs actual run time
   @146w on unit display
   =219wh
   Gives 73% original
   The outdoor results have been repeated consistently several times

   Nice small unit, very easy to carry around in my service vehicle, I’ve drained it completely many times and it charges right back up and is ready to use next day,
   I’ll be ordering a lrger capacity unit soon.
