Anker PowerCore 15000 Redux, Compact 15000mAh 2-Port Ultra-Portable Phone Charger Power Bank with Poweriq and Voltageboost Technology for iPhone, Ipad, Samsung Galaxy, and More

While shopping for a replacement for my 3 year old, yet, still going strong, PowerCore 10000 (which I passed on to a family member who needed a battery pack), I had this: the PowerCore 15000 Redux, and the PowerCore PD Redux 10000, in mind. Ultimately, I ended up going w/ this 15K Redux over the PD 10K Redux. Even though the 10K Redux would’ve given me the updated USB-C & PD in a neat little package, I’ve found it more practical to have an extra USB-A port (as I have more peripherals/cords still using the old standard) and getting 5000mAh more battery. That extra capacity was worth it, especially when offering to charge a friend’s phone, or having bigger reserves for smaller peripherals, like AirPods. The trickle charging feature for devices w/ smaller batteries (e.g. AirPods, Bluetooth earbuds, smartwatches, etc.) is a nice addition. There are a couple of cons: for starters, it is a bit bigger & heftier than my older PowerCore 10K, but that’s just nitpicking considering you do get greater batt. capacity & an extra USB-A port, I guess one significant con is that it is still using microUSB. While it is now prime time to adopt USB-C & PD, it’s not a hassle, especially when one would have microUSB cords laying around. If there was a PowerCore 15000 PD, with one USB-C PD port & two USB-A ports, I’d jump on it. All things said; the main point is that this 15000 Redux serves my needs well. If you’re looking for a high capacity, yet compact, power pack; it won’t disappoint.

I have used Anker battery packs for many years now. They work so well and are so reliable I decided to buy one for each of my nieces and nephews. Now they all have high speed charging that they can carry with them! So far they all love them and not a single one has an issue. I think my brothers and sisters are a bit jealous now. LOL. Well sorry no photos since I don't have one handy to take a photo of. Mine is a bigger model.I did get the opportunity to test one out and they do indeed charge at rated levels, although as with all battery packs you won't get full 1500mAh capacity due to losses in the circuitry and heat of the charger and the phone itself. For the most part if you haven't drained your phone completely you should be able to charge up from 20-100% 2-3 of times on most average phone batteries. Note this model does not come with a charging cable. Since there are so many types and styles out there. It also does not come with the charger to charge the battery pack itself. It is simply just the battery pack. If you need a charger (hi speed recommended) they do have models that come with them.

I love Anker products and feel like they are higher end and safer than other batter chargers, especially with their LG Cells and not some big gel pack inside the unit. This unit is working exactly as designed and does deliver battery power through two ports. It takes a long time to drain it. However its a lot heavier and larger then the PowerCore 10,000 with only one USB charging port (which I own), and duhh, right I'm getting a bigger pack, but its just enough bigger to make it less useful and less portable. Way less chance of it ending up in a purse or pocket. So its relegated to knapsacks and other longer duration travel situations and less around town. Don't get me wrong, its a good product, just be aware of its size and weight, but if you can live with one port and 1/3rd less power, the PowerCore 10,000 is a better size (see my update below - as long as you don't mind it in your knapsack, the extra power is awesome).Also the button layout and charge port and indicators are in odd places. The layout is better on the PowerCore 10,000, but the 10,000 only has one USB charge port.Update: Its larger than the 10,000, but man it seems to pack plenty of power, and it is a workhorse - I just bumped my review up to 5 stars after a few different business trips. I just took a business trip and from the start of the day until the end of the day I barely moved this thing 1 bar on the power meter and it kept my phone at 100%. I didn't even bother to bring an auto adapter for the rental car, I just used this instead. A flight, then 3 hours of GPS usage on back country roads, and then heavy hotspot usage while onsite with a customer. By the time I got to the hotel 15 hours later it will still 3 of 4 dots on the power meter and my phone was at 100%. In real world use its awesome to not have to worry.

Our old chargers have been relatively cheap off market ones, but for my constant trips to Disneyland, those types of chargers wouldn’t cut it, so I decided to get one from Anker, since I have heard so many good things about the charger. And, overall, it’s the best portable charger I’ve tried.The charger charges my iPhone XR really fast, putting me from 10% to 40% in a span of 15-20 minutes. Now that’s impressive. And it’s able to charge my phone up to three times? Incredible.It comes in a size similar to a wallet, or half the size of my iPhone XR. This is an overall decent size, however it is very bulky when put into a pocket. However, for the capacity of the charger, it’s understandable. Also, the charger takes awhile to recharge, but I usually charge it while I’m asleep and once I’m awake it’s fully charged, so this isn’t a very big problem.Overall, this is a very good value charger, the capacity of 15000mAh is just right (not too little, and not too big).

I love that the Anker holds a charge for a long time, and you really can charge more than one device on a single charge. The only thing to be aware of is, it takes quite a long time to charge the device. It's built very solidly, and I like that it fits nicely in my purse. Travels well and has bailed me out numerous times, especially when traveling, when I use my phone more often for photos.

This power band is well built. It lasts pretty long and it doesn’t heat up while charging or recharging your phone. I can change my iPhone 12 about 3 full charges. I have been using this for the past 2 years and I still love it. I highly recommend this power bank
