AuskangSlim Power Bank for travel-5000mAh Portable Charger with Built in USB-C Cable- Airplane Safe Thin Battery Pack Compatible with iPhone16 15 Devices Samsung Google Pixel Android Phones

The battery arrived with 3 lights lit of the 4-light charge level indicator, which (per the provided instructions) means it's shipped at 30%-60% charged. I fully charged it with a one-amp (1A), slow wall charger and the provided charging cable (18.5cm [7-1/4"] long, USB-A to USB-C), which took about an hour to reach 4 lights (60%-100%). (( I prefer to use slow chargers whenever possible, to avoid force-feeding batteries. This is one reason why my S10e is still going strong, after 5 years. )) A wall charger is not provided. I don't know if a 2A (Fast) charger would charge it faster. I then left it charging for another hour, to probably reach near 100% charged.I then used this battery to charge my Galaxy S10e phone (containing a 3100mAh battery) from 40% to 85%, which took about 45 minutes. Oddly, while charging, my phone indicated only "Charging", not "Fast Charging", yet it seems to have charged in Fast time. /Strange./ After the phone charged, the battery still showed 4 lights, which means it still had over 60% of its rated capacity (5000mAh).At no time, during charging or discharging, did the battery seem warm.The pictures on the Amazon website are unclear, but I was assuming that the case of this battery would be plastic, yet I was pleasantly surprised to discover that most of the battery's cover is stainless steel! I appreciate the good protection. Overall, the case is well-built and stylish. It is not water-proof, yet I can imagine that it will keep fine in a backpack's inner pocket.The built-in Type-C USB connector is quite tight to insert into my phone, but I assume that's because it's so new. The built-in wire is only 33mm (1-1/4") long, and is not particularly rugged, so I do not advise leaving this connected while in your pocket, where shearing stress can be intense.Recommended.

Bought this compact battery to travel to Spain so I can carry in my pocket instead of hauling backpack. Went in the heat of summer and learned something about this battery:The Good:- Lightweight- Easy to fit in pocket- Ultra thin- Includes the charging cord, love this feature- 42% iPhone batt to 99% batt charge, still had 2 of 4 lights of charge leftNot so good- Will not work in ultra hot weather. First time I used it outside in 38F weather the battery drained completely and my phone only charged 3% in 2 hours (while not using phone.) battery was completely out- Works great if it’s not too hot outside! Charged 3 times so far in my pocket when not too hot, works beautifully

A lifesaver for long days at Disney! I love that they are so slim and can be held flush behind my phone while charging. These are great quality and well priced.

Built in cable is short and feels it could break off over time. Takes a bit longer to charge up. However this is thin, lightweight, and feels very solid. If you normally need to recharge your phone once while you're out before getting back home or work, this is better than carrying an extra cable and bulkier power bank.

I love this charger! It’s so small and lightweight and I love have the charging cable built into it! I can charge my phone two and a half times with it.

The Auskang Portable Charger is incredibly convenient and slim! It’s so thin that I can easily carry it with me everywhere, whether it's in my pocket or bag. The built-in USB-C cable is a huge plus, and it’s compatible with all my devices, including my Android phone and newer iPhone.The 5000mAh battery gives me enough power to get through the day, and I love how hassle-free it is to use. This charger has quickly become a daily essential for me. Highly recommend if you’re looking for a portable and reliable power bank!

Amazing they were able to make this so thin. Very impressed with the charge as well, it seems to be close to the states mah.

UPDATESadly, I have to take down my glowing review of the product, and update with this one:I have purchased these Auskang Chargers for years now for both my family cell phones and for my employees. They were especially helpful, since what with their amazingly thin “credit card” size, and long-life, you can easily attach them all the time to your iPhones, to keep them at 100% capacity. I have already put in a glowing review sometime back. Unfortunately, all has changed and I had to take that review down and put this UPDATE in. It appears that this company, which seemed at one point to pride themselves on their charges, and especially their high quality, no longer care. Perhaps they now feel they must make more profit by going to a cheaper third-world sweat shop to assemble these and provide much less expensive materials, and “skilled” labor. I have now had to return four of these charges, since within days, the wires inside the body of the charger, connected to the lighting cable, comes apart. It’s not a matter of any force put upon it, or it being accidently “pulled” too hard, it comes out on its own (see picture), since the “cap” that holds the lighting cable to the body of the charger is now, it appears, of extremely poor quality and badly designed. This does not appear to be the construction of the older chargers that I have. I can understand, perhaps one bad charger making its way through the process, but not, after four bad chargers in a row, all having the same problem. The company seems to have now gone to the lowest common denominator in materials and labor, and have given up entirely on any quality control. I’m sure these negative reviews, or many others I have seen on social media, will have no bearing on them to change back to their old, great product. In business, these are known as “throwaways”. Since they now cost as little as $20, they believe they can sell this junk, and a mass majority of their customers will just throw it away. They will not take the time to ask for a refund (extremely easy to do with Amazon), or write negative reviews. Therefore they can continue to rip-off customers, and I’m sure make a nice profit on each unit. Bottom line: there are many other similar chargers on the market, and on Amazon. Chose those but stay far, far away from this cheap and worthless item.
