Anker Powerhouse 90, 87.6Wh Portable Charger with 100W AC Outlet/45W USB-C Power Delivery Port, Portable Power Bank for iPhone, Samsung Galaxy, iPad, MacBook, and More

One of the best if not the best portable chargers I've got.

When it worked, it worked, but it either won't take a charge or it won't output a charge. There's really no way to know why it won't work, but it mostly does nothing. I returned the first one as it didn't work, and Anker sent me a second one. I used it a couple of times camping, but then it died as well. When I plug it in to charge it, some of the lights on the front light up like it's charging, but I've left it charging for a week and it still is unable to power anything. I'm trying to get Anker to replace it with a different product, but it doesn't seem like they're going to resolve this.In short, the brick is garbage and there's no way I would recommend it.

I work in an office that prohibits plugging any item into our laptops, docks, or power strips. I use mine to power a fan all day, with periodic charging of my phone and watch as needed. I only have to recharge every 3rd day. Superb

Runs out of juice very quickly. very disappointed.

Item worked great for an international trip, which is why I bought it. It stopped working after having it for a few months. It will not charge anything and I have tried all of the fixes that I can find on the internet. It is going into the garbage. Please advised that this item has a short lifespan. It is not worth the price. I would not recommend to anyone.

Many may find it a little on the heavy side but you don't get current and/or voltage without weight. It more than meets my needs.

It’s great if it’s something you’ll be using regularly. Definitely not intended to be stored for extended periods of time with no use.Mine is completely dead. I used it in March of 23 and 24 and it worked great, stored it until Beryl hit Texas this month. In preparation for the storm I got it out to charge (started at 20%) and it wouldn’t go past 20%. Used it during the power outage till it completely discharged and now it won’t take a charge at all.I’ve read the description about not storing it past 30 days and that definitely wasn’t there when I purchased it in March of 23, otherwise I never would’ve gotten this. Its original purpose was for camping so I needed something that can be stored intermittently.Great power, good for weekly monthly use, just don’t go past that in terms of storage.

First off this is a nice power bank that can provide 100W over USB-C and also has a built in AC inverter. It is fairly heavy for the battery capacity. It also gets fairly warm when using the AC inverter. If you are looking for a portable power source to keep your laptop or other USB device running all day, this may be a great option. The inclusion of a compact 45W charging power supply is a great bonus.Unfortunately, I purchased this to use with my Resmed AirMini CPAP. The notes in the listing do not recommend using this power source for a CPAP, but I assumed this was because they wanted you to purchase a larger power supply. The listing is even confusing as it lists a 3-4 hour runtime for a CPAP. This would assume your CPAP requires ~20-30W to run. The AirMini only requires about 7W on average, therefore this Powerbank should have provided 10-12 hours of runtime using the AC inverter. That would have been plenty for a night of camping. Unfortunately this powerbank has an energy saving sleep feature. The AC power source will automatically stop after 1 hour if the AC load is less then 8W. This meant that every hour, I woke up to find my CPAP turned off and I had to turn the AC power back on. When it was powered on, the powerbank powered the AirMini CPAP perfectly. Unfortunately turning off every hour is a non-starter for use. What's worse is this power saving "feature" is not listed anywhere in the Amazon listing.I'm sure this is a great powerbank for the many other usages, but be aware if you are purchasing this for long duration operation of low power AC electronics, you should look somewhere else. It is definitely the incorrect choice for powering a Resmed Airmini, unless you don't plan to sleep for more then an hour at a time.
