Poweradd EnergyCell 20000mAh Power Bank - External Battery Portable Charger Compatible with Huawei, iPhone, iPad, Samsung, Nexus, HTC, Nintendo Switch, Tablets and More-Black

The battery on this is excellent it's been great we went away for a few days and this kept our phones charged all weekend.I have a s9 and charged 3 times and my husband's 2 twice and they were still power left in itIts so easy to pop in your bag its not too big.It changed fairly quicklyVery good powerbank well worth every penny

This product is great if you are on the go and wanting a good charge to your device. Ideal for us as we have children that use the tablets in the car and elsewhere so always handy to have a powerful system to recharge those.I will almost always keep this in the glove box now as I tend to need at least 1 charge whilst at work every day and it's just handy to have when I need it. The only 2 criticisms I have is that the supplied cable could do with being a little longer it does the job but if I am gaming on my phone as a lot of people do now. You cant really hold the phone at a comfortable height. Second dly I think they could improve the product I'd it had interchangeable adapters for other devices as opposed to just micro USB for people who may not have there specified charge cable with them or ready at the time.

Almost of my colleague has a power bank, even someone has two or three power banks, because we are wedding company staffs and we often are working outside. I often borrow power bank from my colleague. But it is unconvenient, they often use their own power bank by themselves.So i search power bank at Amazon and plan to buy a power bank for myself. Then i found this Poweradd energycell power bank. Big capacity and slim size is best for me.I have use few days, it works well, didn't become hot when charge my phone. Now i borrow my power bank to my colleague sometime. Because this power bank has two output port, could charge two phones same time.Most part i like is it's big capacity, could charge my iphone6 7-8 times, enough for whole days working needs. Highly recommend.

If you are carrying more than just one smart phone and you have an outdoor schedule for the whole day, then you will need this power bank.It is a beast with 20,000mAH capacity and two simultaneous output. It is handy to charge two devices at the same time if necessary.It is built with plastic but very sturdy. The design is minialist. I struggled to find the power button at first and thought there was none which is not making sense. Finally, after reading the user manual, the power button is located at the centre of the circle indicator, clever!The charging port is a micro usb port which does not bother me at all, although a usb C charging port would be welcome.I did not measure the charging time as it will certainly take sometime. I simply plugged it and left it overnight and in the next morning, it's completely charged.The size of it is not compact and you will definitely feel the weight when you hold it in your hand. But it is a 20,000 mAH capacity power bank, so, it is kind of expected. You can see the size of it is around two post-it note size.Overall, I am very happy with this purchase and would recommend it.

I use as a battery extender for oculus quest 2 - 2m cable, stick this in the back pocket and power lasts a long time. Not quite as fast at charging my Samsung A51 as the mains adapter, but not far off. I've used it to charge my phone a few times and the Oculus headset too. It is strange that it uses an mini USB for its own charging input instead of a fast usb3, but I just put it on charge overnight when it is nearly empty. It does seem to detect when it is not charging anything and turns off.

This item is very well made, and if anything a touch heavy, which to be honest is probably a good thing. Upon arrival it was about 1/4 full, so immediately put it on charge. I've used it a few times now and pleasantly surprised how many times i'm able to charge my Samsung S9 ..... The very first power bank i ever has was a "Belkiin 4000mAh" and that was about 8yrs ago now, and to be fair, they really have come a long way as regards capacity. In a nutshell, yes i like this one, its sleek, compact, designed well, and has plenty of power.

Well I bought the product In January, to use for my trip to Thailand, as I wasn't sure if it would be easy to find power points on the journey. But due to the corona virus the trip was cancelled. I was lucky enough to book another holiday to Malta, and this little device was a god send. I was out taking photos and videos nearly every day and when my phones began to run down, I just plugged in my phone and way to go. The battery lasts for ages and it has come in handy for my nightshirts too, I don't have to worry about having cables stretched everywhere, the only issue I have found, and it isn't really an issue, is that it has to be plugged in for a while to fully charge, but it will get about 5 - 6 full charges and that was with my fone and kindle. I would deffo recommend this power bank. And I intending to buy some as gifts at Christmas for my family. As you can see my cat also enjoyed the little book Mark with the tassle and is still enjoying it to this day.

Original purchase stopped working while charging a mobile phone after less than a month of use while I was on holiday in New Zealand. On my return I gave it a one star review. Following my review the supplier contacted me and replaced the charger. The replacement is working fine, no complaints, I have thoroughly tested it and it is only fair to alter the original review to reflect that.Good reaction by the supplier to an initial problem.
