Fits my needs
Lasts me a full week of car camping, to run a small USB fan every night. Small enough it doesn't get in the way. Charges up quick enough.

Lovely item with 1 problem
This item is made of good material and the size and look are great. The light is also nice, and the unit is generally quiet except when cooling down it produces a relatively acceptable noise. Why 4 not 5 stars? It is supposed this unit can be re-charged in 3 ways, 1: power adaptor OR 2: car plug, AND 3: USB-C. The USB-C can be combined with the power adaptor or the car plug at the same time for faster re-charge. The power adaptor and the car plug share the same plug so one can be used at a time. The problem is trying to recharge with the USB-C. The unit I received starts re-charging on USB-C then stops. I tried different cables and different power supplies to no avail. Although this might be a small problem to most users, yet to me, it was not as I have one application where the power consumption is higher than the power supply provided by the power adapter and combining with the USB-C is necessary to keep the juice flowing. I had several friends complementing the item and taking photos of it with the intention to purchase soon. Charging my items was not an issue and the 110V power supply works well. If you have low power consumption items plugged in then better turn the ECO switch off as the unit will go on standby if you don't and stops supplying power. Had no problems after switching the ECO off.

Anker Powerhouse 521
The PowerHouse arrived in excellent condition, well packed. I was surprised that it did not take too long to fully charge and holds charge level well. It charges our phones quickly. Easy to read displays. Very pleased with my new Anker

Good battery so far, time will tell
So far so good it has become useful in an area where we currently don’t have outlet. Using it to power baby monitor.

Destroys the Yeti 200X
Bought a Yeti 200X and it had to be plugged in all the time and wouldn't hold a charge much long. Bought the Anker 421 and it's a phenomenal little power bank which holds a charge, charges fast and I already charged 5 devices simultaneously! So happy with my purchase!

Good product
I really like my 521, but I’d lose to see more usb-c ports on these as they seem to be the way things are going.

Great Battery Pack
This has been a fantastic purchase. We are able to use it for hours with no issues or worries of it dying. The digital display is very crisp as well!
