Anker Portable Charger, 10,000mAh 30W Power Bank, USB-C in and Out Fast Charging Battery Pack, Travel Essential Phone Power Bank, for iPhone 16/15, iPad, MacBook, Galaxy, Google, and MoreClimatePartner certified

I have a Samsung S22+, and this power bank can charge my phone a little over 4 times. I purchased this product for about 25 dollars and it has been an excellent travel and school companion. I always fear not being able to recharge my phone in case I accidentally had the wrong charging adapter in a foreign country. This power bank lasted me through an eight hour flight and more. Moreover, I dont always have the ability to charge my phone or tablet before lectures, and this power bank has been a life savior for this too. Instead of awkwardly roaming the lecture hall for a wall plug, or forgetting to bring a cable entirely, this power bank lets me worry less and has just enough battery for my everyday use. I think it feels a little cheap, the exterior is plastic so it gathers scratches very easily on the matte sides and on the glossy face (pictures below, only owned for 3 months). One more thing I would like to mention is the included cable. Before buying this power bank I had to remember to carry a cable and power brick, now after purchasing I only carry this power bank around and charge it when I get home. The cable on it feels sturdy and I trust the loop enough to lift when needed (I dont trust is enough to hang off the side of the backpack, it has its dedicated place inside the bag, and the loop is useful when identifying and pulling it out).

This Anker portable charger is powerful. It's a quality build. It charges quickly itself and then does a great job charging my Android A15 phone as well as my headphones. Takes about 25% of the portable charger's power to take my phone from from 10% to 100%. It's rapid charging. It is compact enough to be easy to carry with me in my pocket or purse. It has one built in USB Cord that tucks in to make it a carrying handle and an additional input output port that is also type C. I have purchased several of this version on sale making them an excellent purchase for the price point, although I would purchase them again at full price if necessary. Very easy to use.

I purchased this Power Bank as an addition to my small assortment of banks. I happened to purchase it right about the same time I purchased a Roland Juno-D8. A fully weighted 88 key synthesizer from Amazon. Well it turns out that this power bank will run my Juno plus the 2 lamps that I have attached to the keyboard. Calculating the power draw from the keyboard and the lamps the power bank should easily run it all for up to 10 hours. Of course it can’t run my amps and powered speakers but it does handle the keyboard quite nicely. I own a few different Anker power banks and I love them all. Anker is my go to for portable power banks. Great Company!

I really like this charger battery. I wasn't sure how I would like the integrated cord/plug that plugs back into itself for storage, but I really like that part. It's not heavy and bulky like one I had years ago. I got two of these, one in pink and black. Took them on vacation. I had one in my purse for JIC moments. It did fine. It's compact and easy to tuck in a purse or carry on. It didn't take forever to charge my phone either. I also used it for my Galaxy tablet. I also could plug my Galaxy watch charger into the regular USB port and charge my watch. Because hotels either don't have enough plugs or they are lose from overuse like the one I was at. Very versatile.I like this for travel and I always try to have all this kind of thing charged up on the regular if we lose power. These are good to have around.

Okay, let us cover the good part first: It has great PD compatibility. It can do 5V@3A, 9V@3A, 10V@ 2A, 12V@2.5A, 15V@2A, 20V@1.5A. So, that is more than many other power pack out there. (however there are some limitations that I will get to in the later section). The output is max of 30W (I confirmed it). It says it is 10Ah but that is rated at 3.7V which means it is only 37Wh. I have drained it from 100% to 0% and managed to draw 31Wh out of the pack that is rated for 37Wh. That is 84% which is better than just about all the power packs out there that I have experienced. Most other power packs out there can barely do 50% of the rated capacity or 65% on the better ones. The display is nice to know what % of capacity remaining. A sustained draw of 2A @5V will make the pack fairly warm to touch. The USB-C cable that comes with the pack is nice to have. The size is also fairly compact which is easier to carry.Now, let us talk about the down sides: I cycled my first power pack and tried to measure the power rating. The pack PD outputs died after draining it on a constant load of 30W (1.5A @20V) for about 10 minutes. After that, it can only deliver 5V/2A. Then the cabled terminal shows "low voltage". I am guessing the USB PD IC died inside the power pack. So, Amazon sent me a replacement unit. So far that unit has worked without dying yet. But I would keep an eye on the unit if high power dissipation is needed. I was loading the replacement unit at 1.5A@15V, once it drained to about 25% in capacity, it no longer can sustain that output. Those voltage/amp ratings are really only correct when battery is more than 50% in capacity (that is expected for most lithium ion batteries where peak current output will fall as capacity reduces). The 5V/2A output has no problem sustaining it until 0%. Charging is also not as high as it is indicated. On the back of the unit, it says 5V/3A charging rate, the unit can only sustain 5V/2A charging rate. So, a full charge will take about 3 hours.Overall, it is a decent power pack. I am a fan of Anker products. Although it isn't perfect or delivering everything it is claiming, it is way closer to its claims than just about any other power packs I have used. If the application only needs 5V/2A(very popular mode), then it can last 3 hours easily.General complain, I really don't like how power packs are rated or advertised by xxxxmAh. Why don't we just use Ah? 1000mA is 1A. Isn't that simpler? Also, those ratings are misleading. The Wh is much more accurate. Of course, most packs can't deliver those energy level at all the voltages. So, it is another misleading information. At least Anker has delivered the real world rating that are closer to their claim than others.And for the price, I think it is a great value. So I would recommend getting it over other brands. If a 30Wh pack (5V/2A for 3 hours) is good enough for the application, then I think this is the one to get.
