Review: 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.

Review: Initial Review:

Jeffrey Peterman – ⭐⭐⭐⭐

Review: About 8 lbs, but it has a handle. Both AC and DC (car lighter) charging options. Have not yet tried with a solar panel, but that should work too. Took camping and ran CPAP machine for two nights with power to spare. (was at about 20% on second morning.) Charges fast on AC. Anker claims that the device is both rugged and that the batteries can withstand many cycles. Have only had it for a short time, so can’t verify that, but if things turn out to not be up to scratch, will amend this post. Worth the price.
