I bought mine for 12 pounds
Asus, as described by the company, is pronounced A-soose.
Finally not a stupid review where someone just goes over the product specs. Need more reviewers like you.
Nice power bank…BUT, HATE the Pink. Yes, I know…picky picky! If it can't be bought in a different color, I'd
paint the thing. Here's a unit at higher cost, unfortunately But I like the Blue color.
will this work with the nintendo switch?
I guess the question now is after three years is this power bank still working or has it given up? I have one like it that I purchased in 2015 and it now is having issues. I liked mine a lot as well, but I think it should be better than 2 years. I didn't use mine every day, but I did use it several times per week. I could be wrong, but after I unplug a device from it the fourth LED flashes, so I wrote the company and they said not to worry it has a 1 year warranty, well that is gone. If it is bad I will break it open and charge each cell. Then I will test each one and make a smaller power bank out of the cells that are still good. This is the only store bought power bank I have purchased. I have about 7 other power banks that I hand made myself and they should last as I hand picked quality Panasonic and Sanyo 18650's for those power banks. I think that is the best way to do it if you are able to.
Just bought one from Amazon yesterday for £22 due to it having great reviews. Looks like I chose well.
How do i know if it is fully charged? Does the fourth led stop blinking?
An updated version (3 USB outputs) is now only £23 on Amazon UK (same link as in description)
one of the best reviews I have ever seen, thank you for doing this. I had no idea what portable charger to buy but I am def going with this one!
Thanks for your review of the EC Technology powerbank 22,400. In your estimation is this powerbank adequate for charging 2016 Macbook pro? Please advise!
nice one! Very informative video. Your mathematics prove that the standard process of finding out the capacity of cells is duff. Which I have had my doubts for a while! I'm going to purchase a few of these powerbanks & rig up a battery pack. It would cost around £40 for 8 samsung INR 25R 2500mAh cells.
I got the version with three outputs on Amazon cyber Monday for £12.59.
I bought a similar empty enclosure and put in my own 18650 coming from a laptop. I do have 15400mAh for real.
Double that I have 2 powerbanks now.
They take up to 6 18650s and cost me around 1.8 pounds for each.
Hey, great video! Thanks for sharing. I have the same power bank and I have been doing some testings. First time I got a total charge of 14333 mAh and doing the calculations following your video got a final 21596 mAh; which is 96.41% of the claimed capacity. Impressive right?
I discharged it by charging tablet and phone and when it was all drained, I decided to do another testing. So, after an overnight charging (20hours total) I got a final charge of 17719 mAh in the tester. With the calculations. it gave me a total of 26620 mAh; which is 118.9% from claim capacity (4220 mAh more than claimed). How is this possible? I let it connected and the tester shows it is still charging, slower than at the beginning but charging. Will it reach 22400 or near that? Would it get overcharged? How can it give me more than claimed capacity? Any ideas? Am I missing something? or Is it just a great power bank ;)?
Julian which usb port do I use to charge a bike Garmin? Thanks 🙂
I have sony xperia z2, 3200mAh battery, this power bank is good for my mobile phone?
Was about to buy this for £20 on Amazon, and now a few days later they have stuck the price up to £35 ! Why did they do this, common sense says if you start selling these things, drop the price and sell many more…. I will now wait until the drop the price to how it was a few days ago….
