Great charge, long lasting, easy recharge. Really like it

Anker is a well respected brsnd. I have not used it yet, so all i can do is comment on the charging. The first charge takes several hours. Ive check the status well after the charge. It still is fully charged! I have no doubt it will work as advertised.

Easy to use, light weight, longer changed lasting.

A bit heavy to carry daily. But holds its charge well and is durable.

Keeps the phone charging up 24 hrs , easy to carry

I was a bit confused about how to charge it but when I found I could use my old Power Adapter which I did not throw out when I bought a Apple Series 7 watch and Mini 12 phone So, I just plugged it in and gave it overnite to charge up. Haven't had a power outage at home or need to take it in the car but am expecting it to work just fine. If the grid goes, so does everything else. But, for shorter outages this gives me peace of mind.

I bought two of these, one for my wife and for myself. Super convenient to have especially on emergency basis. Mostly for power outage due to the Hilary storm. Its easy to use, but make sure thr cables are properly connected and pushed in.

Charges quickly, battery lasts long. Easy to use as well.

Took this camping to Coachella. I got three full charges on my phone that weekend while my friends couldn’t get more than half a charge on their Amazon power boxes. Use it daily now! Charges over night and lasts forever.

I'm a big fan of anker products, especially as a third party peripheral, I've tried cheaper chargers which only lasted a few uses before they no longer held a charge, but anker has been reliable for over a year now. It even charges my phone almost as fast as the wall charger. I'm so impressed I purchased 2.

Bought for a trip to Europe and it worked perfectly! Ended up making 3 trips to Europe due to some unforeseen circumstances and it never failed. Get 2-3 full charges on IPhone that was down to 10%. I’m sure there was more left in reserve, but that’s all I needed.

This thing is awesome! Used it recently on vacation when we were out all day and needed access to our iPhones and this thing kept us in power all day. It does take several hours to fully charge up, but when it does it gave us a full 8 hours of all day charging on 2 phones and wasn't even 50% depleted at the end of the day.

I purchased this Anker battery bank to have with me on an overseas trip. I wanted to have a reliable charging source for my phone in case the power outlets at overseas hotels were not compatible with the phones charger. It worked great and enabled me to charge the phone multiple times without issue.

Love this product! Really great for on and off the road travel! Long battery life following a full charge! Very light weight!

Pretty simple. It holds a charge and it charges my phone so basically it works the way it should.

The Anker 20K mAh Portable Battery Charger works great. Charges in a reasonable amount of time for a battery charger that will not only charge several devices at once but also multiple times. Fast charging your device is really nice. Only thing I would change is put a separate pouch for cables on the bag that stores the charger.

Great for traveling. Has a ton of power to keep you going for a long time. Used it heavily on a 14 hour flight to keep the Switch going. Only thing which stopped it getting 5/5 for me was no cloth case included. All the other Anker charges I have included one. Not a deal breaker, but the case is a nice touch to avoid scratches.

So far, this power core has provided excellent charging capacity for my phone and tablet. It also seems to hold its stored charge for a long time when not used. This unit is UNLIKELY to be able to charge up higher demand tech like laptops, so if that is intended, I'd highly recommend exploring this further if it is a requirement.

There is a variety of portable chargers out there, but this one has held up well. I use it for all of my travels and charges multiple devices really quick. Happy with my purchase overall

I lost my previous portable charger and was on the market for a new one. The associate recommended Anker’s products since its a new brand and holds amazong charges. I took it with me on a 7 week trip and always on outings. This really held up, only had to charge it twice.
