Excellent so far charge held

I do love this thing. Charged it quite quickly. Since I got it. I'll check right now how much charge has been held so far.its been quite some time actually since I checked it. Prepping for a long hike. It absolutely works just fine. It's been months no joke.since I checked it. Think I'm a lair (enter worst insult here) planning on A.T. thru hike solar panel in hand.

Great quality, as usual from Anker.

This PowerCore Essential 20000 comes with a nice protective mesh style carry pouch and a 60cm USB A to Micro cable.You will need to provide your own wall charger, I use the phone charger that came with my Samsung Galaxy S10+What's handy about this model, is that it accepts either USB Micro or USB C for charging the power bank. This means I only need to carrry a single cable with me as my phone also uses a USB C to charge.Simple but perfect, the single button on the unit is pressed to show the current charge state of the power bank, in LED form. 4 LEDs on the button itself light up to show you an estimated capacity in increments of 25%, so 1 LED is 25% charge remaining, 4 LEDs the power bank is fully charged to 100%.That's all you need to know about this product to be honest. It will last you for years without any issues.I love Anker products, this is my 4th Powerbank from them and no, that's not because they keep breaking... it's because the ones I have keep getting snatched by family members, they're that good.I bought my first Anker PowerCore 16000 in 2015 and it's still in daily use to this day (by my wife... that's why I've bought this one)When it comes to power banks and charging cables, Anker is the only brand I consider.

Fast charging

The Anker PowerCore Essential 20,000 is a very fast charger it charges my galaxy s8 just as fast as Samsung's charger. Because I use my phone a lot it need to be charged more often and because of this I was always looking for an outlet at work and at college and I always thought that a portable charger would not charge as fast as a regular charger, but the powercore which I charge about once a week (and is still not empty) overnight, last me for the whole week. I also like that it can be charged via USB C so i can use 1 cable for my phone, jaybird vista and powercore.I really love this product and Anker.The only bad thing I can say is that it is pretty heavy but that is understandable as it is a very big battery.

Great charger

I actually about 4 charges out of it before I have to recharge it. (Side note) I don't let my phone completely run down. I also use it the charge my Samsung buds earphones too.

10/10 would recommend!

Saved me from having a dead phone for 3 days straight.I had to go to NY for a sudden unexpected trip. And my phone is a 5 yr old LG that only last about 10 to 12 hr MINIMUM usage. But since i never been to New york and had to rely on Google maps 24/7 so my phone only last about 6hrs. Good thing I had this. It kept my phone alive all day until i get back to my room. It comes with a cable long enough to comfortably use your phone while plugged into this (i kept mine in my coat pocket)Weight is pretty hefty. I also dropped it multiple times on accident but it seems to charge everything normally. I would totally recommend this to everyone.
