  1. Robert T

    I just got done testing how much phone battery I can get from this. I charged my Samsung A51 from 18% to 95% while using the phone heavily (gaming, using apps). Then I charged it again from 14% to 87% (also under heavy use) before the charger ran out of energy. This translates to around 1.5 full battery charges, going from 0% to 100%.This is absolutely plenty of charge for a full day of heavy phone use. When I bought this I was worried it wouldn’t have as much charge as I wanted in case of an emergency. Definitely not worried about that now, and I’m super happy with this purchase.Other notes: It’s lightweight and is about the size of a cell phone. It doesn’t show exact charge percentages, but it has 4 small lights, and if all 4 lights are on then the charge is between 75%-100%, 3 lights means the charge is between 50%-75%, etc. This is perfectly fine in my opinion.Also, this can only charge one phone at a time. If you need to charge multiple phones, or need multiple days of charge, then you’ll probably want to go with a different, more heavy-duty charger.

    I love this thing and my family loves it, too, which is why I had to buy a 2nd one! It charges up quickly for use and is only slightly slower than plugging your phone (or whatever) directly into the wall. It’s slim and light, so it’s easy to carry around. My mom could figure it out, so it’s obviously easy to use.

    Years ago, my old iphone had that battery issue, where it wouldn’t stay charged up as long as a newer phone would have, so I got in the habit of keeping a couple of power banks in my purse to charge on-the-go if needed. A couple of newer phones later, I’ve stopped relying on the power banks so much, but I still carry them, just in case. The other day, they came in really handy when a friend’s phone was nearly dead, and she didn’t have a way to charge it. That’s when I realized my power banks were really old, and though they still work well, I wonder how much longer they’ll last. Surely they’ll wear out at some point, right? So I came to Amazon looking for a new one. I wanted to stick with a known brand, and this Anker power bank was low-priced with a coupon, so I grabbed it.When I took it out of the box and checked it, 2 of the 4 lights were lit up, indicating it was 25%-50% charged, so I plugged it in. But when I checked on it an hour later, it was still only 2 lights. I was concerned that maybe I got a dud, since I expected it to show faster charging progress. But then I saw something in a review or product description that said it takes around 5 hours to fully charge. Plus I realized my biggest old power bank was only 6500mAh, so it makes sense that a 10000mAh would require more time. I then forgot about it till the end of the workday when I was packing up my things to go, and sure enough, it was fully charged.So far, it’s a great little power bank, enough that I can charge up my iPhone 11 a few times before the power bank needs to be recharged. I don’t really care that the USB-C is input-only, since most of my devices (and therefore my charging cables) are either micro-USB-C or lighning to USB-A. In fact, I think I only have two cables that are USB-C, so I likely would never use it if that port was available for output…though I certainly understand why other people might wish for that feature. In any case, I’ve had good luck with the Anker brand, and it looks like this power bank is another winner.

    A really good choice for starters. The charging power is really solid, it charges my phone in about 1 hour or a bit more, and it only take one of four point of battery of the portable charger. At least that is how it worked for me, it might differ from other people’s opinion depending on their phones. Overall, it is one of the best choices available in the market.

  5. Amazon Customer

    I bought this a few months ago as ’emergency backup’, if I happened to be away from a charging source (so, not in a building or car; generally for camping and the like). The battery in my Galaxy S8 has degraded over time, and I wasn’t ready to get spendy on a new phone, nor did I look forward to ‘cell phone surgery’ to replace the battery (the days of popping off the case back and swapping out in a minute or two are long gone, sad to say). So I ordered this up. At 10,000 mAh, I figured I should get enough charge to get me through a jam.If you’re thinking… “S8! That’s a dinosaur!” — you’re likely rocking something much more current, and aren’t worried about off-grid power. Yet. But remember — all batteries degrade with time.After having used it… my thoughts- Takes a bit to charge up, once discharged (so once you’ve discharged, plan ahead). Especially the first time.- However, once it’s charged up, the self-discharge rate is slow, so you don’t have to constantly keep it plugged into a wall wart, etc. You can charge this up, once conditioned, and pack it away for a few weeks to a few months.- The 4 LED meters on the front are handy for determining SoC / Time to Charge- Form factor on this is very similar to the dimensions on my S8 (although a little thicker, and of course, heavier)- A shorter USB A <> USB-C cable does double duty — USB A to bring the charge to the phone / device via USB-C, then remove & flip USB-C into the input of the Anker, while plugging the ‘A’ end into any compatible port to recharge it.- Comes with a black cloth bag with drawstring closure, which is nice to keep that short USB cable together with the device. Nothing fancy, but useful.- And probably the best, after using Qi-Wireless for 90% of the time over the life of the G8 — this thing puts juice into the phone, quickly. I can go from 5-15% charge to 30% in under 30min. Not sure how many amps it’s charging at (rated at ‘up to 12’ -?), but it’s definitely quick. If you’re caught somewhere without power (or even if you’re not) — this device is a lifesaver (figuratively & perhaps literally, I guess).Technically, I guess you’re not supposed to use the phone while charging with a power bank, but it comes in handy for those times where you need to use the phone a little longer, but need a little juice to tide you over (it juices the phone so fast–especially vs. Qi-wireless–that you say “I might as well just keep it hooked up to this)). I think it’ll charge close to 100% in about 90 minutes, maybe less.- Since my G8 battery is ~ 3800 mAh (?), I can get up to two full charges out of this thing, or many ‘partial’ charges. From full, 30 minutes’ time on the G8 doesn’t even remove one ‘dot’ from the 4-light meter. This is real value, in my book. Because most of the time, I can get back to a power source in 30min or so.So… for what I’m using it for, which is to buy time until I decide to finally (!) upgrade my phone, and keep the S8 running a little while longer… it’s an excellent accessory, from a trusted company. Since this has been out a while, and been superseded by higher-cap devices, solar-capable chargers, etc. — it’s also cheap — about the cost of one of those replacement battery kits (with batteries that came from who knows where).Not often I unequivocally give the full 5-stars… but this product gets them from me. Recommended.(oh, and mine came new in a box, so if yours doesn’t… get in touch with Anker for a new replacement)

    I have two of these, one that can charge 2 devices, and one that has a port to charge one device. Very hand for flying and spending time in airports, for use if the power goes out, for use if your phone “dies” for the fastest recharge, I’ve ever seen, and I could go on. I have used these to charge my phone, when the battery is low, but I don’t want it plugged in and charging in another room, as I want it with me as I watch TV, lol. The charge on this portable device seems to last forever, as well. I generally keep them both plugged in all the time, and when I leave the house I grab one for the car, just in case. Obviously they work anywhere, but bring one on a boat, on a flight, on a hike, on a long bike ride, etc. I should have had these a long time ago.

    For traveling folk, this may not be the best choice for a portable charger due to the lithium batteries it contains; but if you’re in need of a charger for your daily needs, this will do the trick! It charges very fast when using your average Apple phone cable and has a decent battery life. It even came with a small mesh case which I really appreciated.

  8. Amazon Customer

    This charger is Great.I recharged my iPhone 10,3 times before I had to recharge the charger.It’s Great for long trips we’re you can not find an outlet right away.If you are on the beach and your phone battery is low this charger is Great!If you have a power outage in your home and need to call for help it’s nice to have this charger on hand.Just make sure you completely fill the charger before leaving your home to go on a trip.Also keep it charged even when not traveling in case you need it in a power outage.

  9. Ryter Newtype

    Aside from one huge missed opportunity, this battery is great.I have had many batteries since long before the Pokemon Go battery revolution.Now, I have even been on the go and given some away because they were old enough though still working great, but the size now feels clunky.This battery is slim and perfect for the capacity you enjoy.The only real negative is that you can’t charge USB-C to USB-C…which might make it feel slightly dated. But it charges very well (so far.)at least I still have tons of cables that work with this. though I mostly stick to cables that are USB-A to USB-C. There no wireless charging but I already knew that going in.

    Easy to use. Easy to charge, easy to connect to any device. Pocket size. Good load indicator. We use it for an old iPad mini that has a worn-out battery and it holds up all night. No heavier than you think it would be. Accepts any USB cable we’ve used. Charging time is acceptable and really does hold the charge well
