I have one and love it charges my headphones and bluetooth speaker daily at work on the work truck that doesn’t have a 12v or cig. lighter outlet and of course the cellphone. I have a samsung galaxy 8 and it charges it very fast. When these things where on sale the first time a few months back people where hating on it because it didn’t do this or that but it does this and that just fine for me so get one.
@Seeds I had one develop problems where it would stop charging devices a few minutes after plugging them in. Anker support replaced the battery without any hassle at all, so I can vouch for their customer support on these.
@Seeds@tugnutt One comment indicated though that the warrantee only lasts 18 mo though. All rechargeable batteries eventually bite and I have no idea how many charges this one takes to bite. Also amazon indicates there is a newer model available - other than adding one more kind of port no idea if there are functional changes that matter.

I have this happen all the time to certain devices. If you plug a device that has its own battery (for me it is a bluetooth transmitter I plug into my receiver to use wireless speakers with it) and the device is plugged into a “smart” port, when the battery in the device is charged up, it tells the “smart” port to shut down.
The problem is that the device then starts using its own battery to run, but there is no mechanism to tell the “smart” port to start charging again. That only happens when you physically plug in the device.
My solution was to plug the device into the “dumb” port of the battery.
Perhaps that is what is going on with your situation, and it isn’t the battery at all. It’s the “smart” USB power protocols are not designed for a battery/power supply to charge a device, shut off, the device keeps operating, but powered by its own battery, and when its internal battery gets low, it signals to the external battery/power supply, to start charging again.
This is problem has already been solved with all laptops, but that power management hasn’t made its way down into the small battery powered devices like BT adapters and speakers and headsets. i.e. the ultra-cheap chipsets used in them, and they weren’t designed to be operated continuously while charging.
@katbyter i could list on 1 hand the things where brand name matters, and power supplies are on that list. stick to aukey, anker and the major device manufacturers or risk bricking a 500$ phone to save 20$ on your charger.
@tjamesturner problem is how does anyone know what is a “name brand” on anything anymore? Some things are all the same core product with different brand names. I’ve never heard of Anker or Aukey. But I haven’t bought a power brick in several years. I had a 20k Energizer induction charging brick that I loved. A brand name I actually recognize. But it died.
I’ve had the larger 26 Ah Anker charger for 3+ years. It’s been a solid power bank that’s used weekly by my wife and kids. Every other Anker product I’ve ever owned has also been top notch. Meh sold these 20.1 Ah power banks in January and I grabbed one. I held onto it for about a month before I opened it and charged it up. After it was full, I tried to charge an iPhone and it would work for 4-5 minutes then shut off and stop charging. Thought I had a faulty cable, so tried several other cables that I knew worked with plug-in chargers. Still no-go. So I contacted Meh not really expecting anything and was fully refunded. The short: Meh customer service rocks, Anker makes great stuff, but this charger is hit or miss. I want to jump on this deal but my bad experience with this model a few months ago is holding me back. It’s killing me to not grab this. Hmmm…
@shrewsbury Replying to myself. I caved and bought this deal. Wish me luck, but I think Anker’s overall quality is just stellar and I happened to get a rare faulty unit. Meh’s awesome customer service pushed me over the edge.
I have the Switch edition of this one, and I love it. I rarely actually use it for the Switch, but it’s a really good battery pack for everything else. (Unlike this one’s 2x USB-A and 1x microUSB, mine has 1x USB-A and 1X USB-C, and the C works as both input and output.)
Any thoughts on how long it takes to charge one of these? Got my two today - have had one plugged in for 6 hours now & still one light lit & 2nd one flashing … also top end is pretty darn warm. Is this normal?
PowerIQ and VoltageBoost combine to deliver the fastest possible
charge (does not support Qualcomm Quick Charge). Recharges itself in
10 hours with a 2 amp charger, phone chargers (generally 1 amp) may
take up to 20 hours.
In my experience, with a good charger, overnight charges it, Then you’ve got power for days of normal use, even over a whole day of extremely heavy use of a phone with constant use of screen, gps and network.
For all those wondering about the time it takes to charge these batteries, they are themselves USB devices. USB ports deliver 5 V and 500 mA.
So, a 20,000mAh device, from empty will take 20,000/500 hours to fully charge. Doing the math, that’s 40 hours, or about two days charging.
So half full (mine were, with 2 leds showing) will take an 20 hours to charge, or an entire day.
An overnight charge of 8 hours should get you 20% (1/5, or maybe one more led) of a charge.
The bigger the battery the longer it takes to recharge them. It’s also a sign as to how how massive the capacity is on these.
Overall, I’m pleased with them. Although I’m not a big fan of the long shape, though. I prefer a design that stacks the batteries (guessing these are 18650s) wider and thicker more like a paperback book shape.
For the price, with VMP and a PastaDrop coupon, they were a steal.
@mike808 Good to know. I am charging (started on one led showing) one that is a birthday present for a family member. I didn’t want to give an uncharged item. Well and knowing meh, I wanted to make sure it worked too.
@mike808 While not a fast solution to re-charge, the number of times it can be used should make up for it, especially if the person using it has a second one that recharges faster that can be used while this one charges. Or if they keep up with keeping it charged every time they have to use it then it should be fine charging over night.
