Works perfect. Love the auto off switch once an item is charged. Shows how much power is coming out for each item connected. Charges very quickly and it puts out enough power for what I need. Ran my 30L fridge for 40 hours and still charged some cell phones and head lights while camping. Seems and feels like quality item.

Purchased Feb 2022. Tested with various devices and recharging via solar panel and wall power. Charged to 100% and put into storage "just in case."Retreived May 2024 for a camping trip. Still functional and still had 81% battery after more than 2 years without charging.Anker for the win!

Bought for emergence back up for CPAP and phones and haven’t had one yet. But can share observations. The display on front is helpful and accurate. When I hooked it up to top the charge, it said 30 minutes to full charge and was right on the mark. Using the same display I hooked up my ResMed CPAP. With the tank and hose heater turned off plugged into AC inverter, the display showed 35 hour estimated run time. Using the DC plug in (with DC cord purchased separately) it showed 60 to 80 hour run time. It also tried powering our adjustable bed fram and power recliners ( nice to be able to move these in power outage. Handle each easily. The USB sockets will be helpful when needed for phone charge and the LED light on the unit also a nice idea. Nice well designed unit.

Um, i probably use this for things it isn't intended for... sheep shearing, egg candling, etc. So far this battery is a beast! I charged it right out of the box. No issues. I sheared two sheep and candled 60+ eggs, the battery is now at 65%. I'm so impressed with this portable power source. It's so easy to use, but I recommend reading the instructions to help maintain the battery life properly. This thing has been out in the field and in the duck pen with no problem. Its next task is running lights, a radio, and being the barn's power source. (Eventually we will get real power to the barn.)I'll let you know if my opinion changes, but for now I'm loving this thing.

I have a Schumacher power bank to run my astrophotography gear, which uses 10% a night, but will not charge my laptop, which only lasts 6-8 hrs.I needed a power pack to recharge my laptop so I could go dry camping and recharge my laptop for 3 nights of astrophotography.The Anker 512wh was on sale for $150 off the normal $499.After arrival I charged it to 100% and then over a weeks time I put it to the test.1. I recharged my Dell XPS 15* 5 times.2. Recharged my Galaxy Samsung S21 4 times.3. Ran a portable refrigerator for 30 minutes bringing the temp from 70° to 32 °.4. Ran my astrophotography rig for 1 night.After all this I was down to 15% charge.In conclusion, well worth the price, will recharge the electronics I need and is small, lightweight and very portable.
