The charge on the power bank stays (not fully tested, it may stay for longer) for a few days if you do not use it, which is a good thing as I only use it when needed. It stays in my handbag as an emergency.
So far so good, I am a big Anker fan so I’m happy with it.
Will charge my mobile phone very nearly 5 times before it needs recharge. Recharges quickly.
Brilliant, Unfussy, and easy to use.
Comes with black string bag case.
Really glad I got this – saved me when I had to be out and about at a conference with rare access to plug points. Takes some time to charge up in the evening or overnight but seems to do a lot more than the advertised 2x iphone battery so I was never worried about running ou
I used it for two weeks as battery of my old phone was draining fast,so it was good to have it. In the end I replaced my phone. Was a great help. Will now use it for emergency purpose.
Does what it’s supposed to do if you follow the instructions.
The charge doesn’t seem to last as long as I would have hoped but it’s fab
My older children have the Anker powercore 20000 bigger version and swear by them, they’ve had them for years. This was after eldest son had researched the best brand and chose Anker (he’s right! They are reliable and good quality). After about 3-4 years of constant daily use, they find they need replacing. That’s great longevity, far more than any other brand we’ve tried.
So I bought this lighter weight slimmer one for me and my youngest child to share.
We wouldn’t be without it now! Comes with carry pouch, charges up easily itself (a circle of blue lights show you level of charge it has) and most importantly it fully charges my phone so quickly. I watch the phone go up 10% every 5-10 minutes attached to this. A fully charged bank will entirely charge my phone about 3 times. I slip my phone charger cable into the carry pouch when I go out if I don’t have time to recharge my mobile at home. It fits easily into my handbag.
Make sure you charge it fully at the start and then use it at least every few weeks (don’t leave it in the drawer so that the powercore bank doesn’t die early! Use it or Lose it!) it holds its charge well but then we use it several times a week
Charge power is quick and can get at least 3 charges out of it. The only downside for me is the size as I like to put it in my pocket whilst out for long and need a charge on the phone. I tend to use my smaller one now if I haven’t got my large backpack to house this one
The battery on my phone doesn’t last long enough when I’m out on a walk. Now with this power bank I could cover triple the distance and still have power to spare. It’s very good. When the power bank is depleted it takes a good few hours to recharge, but that can be accomplished over night. Very happy with this product.
Had a micro usb slot in the input section but if i plug it in its doesnt charge ||. Need usb c to charge it im guessing
Bought 3 of these for a family holiday to Crete to keep everyone charged and happy. Did the job very well! Quite large but powerful and light.
So easy and quick to charge and seem to last forever when being used they are the best battery I’ve ever bought.
Super portable charger, fast, light weight compared to some, simple to operate and great size fits into a handbag no problem!
So far so good. Can charge multiple devices quickly. Reasonably compact for the powe
I had hoped that this battery pack would be less bulky. However the smaller ones that I have seen were more expensive so I am not unhappy.
The capacity seems to be enough to charge my iPhone SE2. About 4 or 5 times and from zero to full takes about 1.5 hours. Not as good as charging from the mains, but not bad.
Charging the pack takes longe
Good value, roughly the same size as my Xperia XZ3 at around 5-6 inches long, fairly thin too so it can easily fit in your pocket if you don’t have a bag. It has one USB port and can be charged by either Micro USB or USB C.
The only negative is the single USB port so you can only charge one device at a time.
Charging takes a few hours but provides my phone with just over 2 full charges and has a Bluetooth earphone charging mode if you click the button twice to show the green LED.
Detailed charging times:
66% – 91% in 48 minutes – 25%
7% @ 10:52am
100% @ 1:04pm – 93%
6% @ 7:54pm
100% @ 10:19pm – 94%
23% @ 1:15pm
35% @ 1:38pm – 12%
224% total charge of Xperia XZ3
Was a bit dubious as it was one of the cheaper ones but it has been brilliant highly recommend
I love Anker power banks. This one is slim and lightweight while so able to charge my phone fully 4 times. Couldn’t be without it.
Bought for my daughter, lightweight easy to carry with you all day. Great to top up low battery throughout the day
Keeps my quest 2 going for hours! Takes a while to charge it though.
I’ve tried other “Anker Power Bank, PowerCore Slim 10000 Portable Charger, Ultra Slim Battery Pack, Compact 10000mAh External Battery, High-Speed PowerIQ Charging Technology Power Bank (USB-C Input Only)” but out of all the “Anker Power Bank, PowerCore Slim 10000 Portable Charger, Ultra Slim Battery Pack, Compact 10000mAh External Battery, High-Speed PowerIQ Charging Technology Power Bank (USB-C Input Only)’s” I’ve tried, this one is definitely a battery.
Easily portable as it’s made with a material that makes it less likely to slip out your hands, charging power lasted me about 8-9 hours
However It does take quite a long time to get to a full charge, took me about 6-7 hours to fully charge the power pack.
Great product. Charges my iPhone XR from empty to full in just 90 minutes. This product is a life saver.
This is a great charger and I honestly feel this charges my phone faster than an actual mains socket.
Product is great but first one I had had a fault after couple of weeks, but customer service were excellent and after couple of quick emails to determine the problem a replacement was shipped very quickly
I use this when I go walking & use my phone more fore photos & videos, it keeps my battery topped up & lasts a couple of days
Instructions not great but it does it job. Not used much n not for long so can’t comment on charging power yet!
Used for 2 people over 4 day festival still had charge on Anker power bank when we got home
Great value for money
Used this at leedsfest to carry round in my bumbag to recharger my phone during the day. Charged it quickly and was light to carry round all weekend
Anker is a name i trust love this battery bank
Really quick charging power, lasts for 4 charges of my iPhone, very happy with it!
This is a very night quality product, light weight and holds charge for longer duration.
This was a birthday present the power last long and very powerful
I like this power bank. It’s portable. Fits in your pocket with no problem. Having the blue dots to show how much charge is left is great.
My third Anker powerbank and this is the best one yet, charges my Motorola G5 2 to 3 times, has a clever lower charge option for my Bluetooth headphones. Only charges one device at a time but it is quick, and that’s enough for me. Size-wise for travelling it’s more of a handbag/small backback weight than a pocket charger, but not too heavy for a coat pocket, if needed.
Does exactly what I want. Provides me with portable backup power for my phone. I get about 2 full charges of my phone from a full charge of the power pack.
Used Anker products before so purchased the 10000mA power bank with confidence. Delivery prompt, product well made. Obviously at time of writing review product little used but happy so far. Supplied a device with a 400mA draw for 3.5 hours and device still shows full charge, this is as expected as approximate draw is 1.6 amps so if full capacity is accurate then over 8000mA still remaining, hence 4 LEDs still showing
Absolutely amazing!! Charged my phone and vape fully 4 times each over a weekend whilst camping. Can’t fault this product at all. Fantastic!!
The product is used for traveling found it very useful battery life is very good
Arrived as promised, perhaps a little heavier than I expected, but I’m sure it will do the job. I haven’t used it in anger, but no reason to expect it will be other than very good.!
I keep this bad boy in my man bag all the time and use it to charge my phone, headphones, my Garmin watch, whatever I need. It works well, seems well built and can charge my Pixel 4XL about 3 times over. Very happy.
Great to use with my iPhone se charges very quickly
excellent. small in size and charges my iphone really quickly which is what i was after.
Priceless for holiday, no fear of running out of phone battery. Well worth the money
Awesome bit of kit. Great product and price. Thank you.
Really pleased with this charger. It’s far more powerful than my old one. It’s quite a bit bigger than my other but it’s much slimmer.
Charges phone quickly and 4,maybe 5 times on it’s own charge.
I couldn’t imagine living without it now. I charge it at night and it last for the day for me. With me everywhere I go. Definitely a recommendations from me.
It does take a long time to charge but it can charge my Samsung galaxy s20 fe around two times from 15% battery. Also used it to charge my watch as well.
LOVE this charger. Take it on nights out with me, it is basically the size of my phone (though a little heavier) and can charge mine and other friends phones and still not run out:)
This is a fabulous charger. I bought it for my iPhone and I can charge the phone fully twice with this charger and still have charging power if needed to top up the iPhone again. Cannot fault it!
I already own a larger Anker Power Bank which serves me well, but I needed something smaller due to the circumstances I was in at the time. I found really useful for when the battery on my phone was beginning to wain as I was using the maps App a lot. The size is comparable to say an iPhone 6 and isn’t too heavy, easy to use and good quality with charging indicators showing how much charge you have left and comes with a charging lead and pouch.
I now keep it in my laptop case as a back up for my phone to power up whilst on the go. But also take it on my long trekking walks as it light enough to go in your bag and not notice it. It has become very handy.
Perfect for if you are on the go and run out of battery life, slips easily into your pocket, lightweight and excellent battery life
It’s very handy and not to big. It does the job.
I love this power bank it’s so useful and handy. I can’t go out without it. I would highly recommend this! I’ve had other power banks but not like this one.
Great product. Maybe kind of obvious but get a speed charging enabled cable or you can’t use the speed charging function on the battery bank.
The best gadget I’ve bought. My Samsung phone wasn’t last long when out doing parcel deliverys, this power bank kept it at 100% and I get 3 full recharges out of it.
Great power bank. Works well on iPhone XR
Gives about 4 full charges and light weight.
Amazing battery life will charge my phone over and over in a day. Sometimes even lasts me the whole week!
It give me about 3 full charge and that’s it and it took long time to recharge about 8 hours to fell all the 4 blue lights am regret to buying i
Love this product helps me with my outdoor activities all day as I use my phone for work
I’ve strapped this to the back of my oculus quest 2 and it keeps it charged whilst i play, really great product overall
Charger is thin and light, perfect for carrying around in your coat or trousers.
Ideal if you are using just to charge your smartphone or keep it topped up throughout the day
My house is full of anker products and this is another to add to the list of quality items
Love anker. Best power bank by far. Not too heavy and charges well
Just what was needed in terms of size, weight etc …haven’t had it long enough to fairly comment on its battery life yet…
The LED indicators on the new version have much more limited visibility than on the original – you almost have to be looking directly down on the newer power bank to see what level of charge it has, although the button to check charge level is better placed on the new one, being combined with the LED indicators.
New version has a USB-C input (only) which might mean a shorter time to charge power bank if you have a suitable cable? The cable supplied is standard USB to micro-USB.
On the plus side, it is currently cheaper as there’s a 5 discount and also a voucher available.
As usual with Anker products, beautifully packaged and the box includes a carrying pouch as well as the supplied cable.
Recharging my phone seems to work as expected (but only a partial recharge so far) so overall I am happy, but I think I would have been at least as happy with the older version (which my son happens to have, so I’ve been able to compare for real) if it had been the same price and it would have got the full 5 stars compared to the 4 I’m giving the newer one as I don’t think its description or the LED indicators are as good.
Need this to charge phone in hospital. It’s seems great.
Still rocking a Samsung Galaxy S6 and even though I personally replaced its battery with a genuine replacement. I seem to find that with its internal 2500mAh battery it struggles to provide power for the phone when i am out and about and away from a charger for the day. With my usual daily routine, I commute by car to work so the phone is always plugged in charged whilst navigating and when I am in the office the phone is occasionally on my wireless pad charging.
On days where I am away from the charger for a day you really have to be careful with how you use the phone.
Some will say, just buy a new phone, however even new phone’s battery capacity average around only 3500 mAh which will struggle to provide a day’s worth of power
The exception maybe perhaps the flagship like the s20 ultra with its mega 4500 mAh battery. However this phone is over 1000 so out of most people’s reach.
I needed a battery bank for those extended periods away from the charger whilst being reasonably priced too.
There are so many offerings out there, however being lithium Ion battery technology there are many safety concerns.
If the internal battery is poorly managed, it can result in overheating and exploding batteries.
This is where Anker springs to mind, after reading many reviews, their battery banks seems well priced and very reliable.
I opted for the 10,000mAh version, which comes similar sized to the actual galaxy S6 phone.
With its capacity, it can charge the phone 3 times, therefore perfect for those extended periods away from a charger.
I managed to wait for one of those offer days and bagged it for 17.
Upon arrival, I was very pleased at the build and quality of the battery bank. It comes very nicely packaged too.
The included cable is of great quality and not a cheap Chinese cable that will last a few weeks.
It also features a small LED indicator showing its current charged capacity which is a nice touch.
The bank also featured power IQ and voltage boost charging. This was very noticeable when charging my galaxy S6, it charged much faster than the original 2 amp output wall charger. This was quite a surprise.
I have now used this on many occasions, and it is a godsend from those extended periods away from the charger.
It can also just about fully charge my Samsung tablet (TAB S – t800 model), this tablet has a 8000 mAh internal battery.
Pretty impressive.
Granted it is alittle bulky to carry around, ideally suited to place in a jacket pocket in winter.
However during the summer periods you literally have to pocket it in your jeans, but being pretty slim its not too bad and worth it considering the benefits it gives.
Purchased in De 2019 and still going strong to this day (Aug 2020)
You can get various versions for your requirements, micro USB, USB C version and lighting connector version for Apple.
They also do smaller versions if you feel this type is abit to big.
A great reliable brand and a highly recommended purchase.
Brilliant product charges the phone maybe 5 times before it needs recharging itself. Very thin and light weight and a very good brand.
It certainly lived up to its predicated time scale of being able to fully charge in around 4 hours using the recommended PD supported wall charger and cable, another reason to consider this remarkable power bank with its distinctive features.
You also have the added advantage of its universal compatibility of being able to charge devices which do not have lightning capabilities.
With its slim and compact design and trickle charging mode for low-power devices this is certainly a great power bank to contemplate purchasing as Anker is a global renowned company which you can trust.
It might not materialize but if you were unfortunate enough to suffer from a power cut you would still have the capability of being able to recharge your devices with this Anker Powercore Slim 10000 PD which would obviously enable you to keep in touch with friends and family.
So I am extremely pleased with my purchase which exceeded my expectations.
Great portable charger with enough power to recharge iPad Pro. Not too heavy considering the capacity
Quick delivery, used it at the Cheltenham races to recharge my phone and people I was with. It was very popular.
Anker products are always brilliant, and this is no exception.
Works well, small and nice sleeve. Be warned, you cannot charge your phone with a USB-C wire using this product, the reason I bought it.
Super happy with this item, works exactly as described, is super portable, lightweight and easy to use on the go! Definitely a lifesaver while travelling and using my phone for Google maps and taking photos!!
Not too big, fits in school bag well and keeps my sons phone charged without any hassle
This power bank is slim enough to fit in my handbag but powerful enough to get 2 full charges out of (my phone is a Galaxy A7). Very happy with this purchase.
A very lightweight powerbank fitting nicely in your pocket. USB C cables connected from it to your phone charges it quickly enough for to charge it twice in one go provided it’s charged to 100% before use!
I have 3 of this battery’s already for whole family. They are very light , small, and last foreve
Edit:
After submitting my review i recieved an email apologising that i wasn’t 100% happy and also offered me a USB C cable free of charge. I was shocked with how great their customer service is, most companies would just settle with the sale and ignore reviews but the thought and response shows that Anker truely care about their customers and i will use them again going forwards.
Rating upgraded from a 3 to 5 sta
Honestly great charger, I bought one for my girlfriend’s brother in law (similar personality) and I’m ashamed to admit, I was jelous so I bought myself one before his had even arrived… Still convinced it was worth the money.
On my husbands Christmas wish list. He is very optimistic it will live up to its claims of eternal power for his iphone
I was deciding for a while which power bank to buy, and when I saw this i had to have it. I was looking for something smaller but still for more than 1 charge. The looks are pretty smooth too!
Saves me a lot of stress, slick and productive. Hoping it would last and perform without deteriorating within 1yr!
The most impressive element for me is the speed at which it charges my phone / headphones. I’d say my phone charges quicker using this than it does via the mains charger. A ten minute charge seems to take my phone from 20% battery remaining to 50%.
It has good capacity. I have fully charged my phone twice and given my iPad a hefty boost before it’s run out of juice. The trickle charge is a helpful addition, allowing me to charge bluetooth headphones too.
The only gripe (not significant enough to knock a star off in my book) is the indicator light that show how much power is left in the battery could be better. They take ages to drop from 4-lights remaining to 3-lights. Ages from 3-lights to two, but a lot less to go to 2 and 1 light. I don’t think this is a big deal though.
On the whole, I’d highly recommend. If I lost mine tomorrow, I’d buy exactly the same again.
his is ideal if no battery left, update phone, Tablet- what eve
Charges very fast with USB-C and charges devices very fast. Very compact and portable due to its case. Highly recommended
Stylish, comes in a nice soft case. Just wasn’t as slimline as I was expecting.
Loved the battery pack! So useful for charging all of my devices on a daily basis. I charge my Sony MP3, phone and fitbit with this nearly every day. Compact for a students bag, can fit in my pocket very easily and overall definitely the most useful I’ve every bought.
Great product and great customer service from Anker!
My order arrived promptly. There was an issue with the cable. I emailed Anker support and they immediately sent me a much better cable as a replacement. Thank you Anker.
Will power my iphone 6, ipod and Kindle several times. Great for the beach or just travelling about. Same weight and size as a smartphone. Just remember the leads for your devices.
Its a good size not to big or to small good for travelling
Just got it so hopefully it will do the biz when I need i
Not had enough use to test battery life. This replaced an older and much heavier one that was stolen. Travelling- great as it’s light and slim
Anker has become my go-to brand for power banks and cables, I’ve been using several of their products now for years.
I’ve tried other ‘leading brand’ power banks but none hold up over time or charge as consistently as the Anker ones. Can wholeheartedly recommend this product.
