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.

Fantastic. Fast charging. Really slim so you can put it in your pocket and it even has a permanent cord. Perfect for a daily problem if you run out of battery. It is small so it only charges about one and a half device is on a charge but it's great for its size and it does fast charge.

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

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 power bank! I love how lightweight and thin it is! The battery life is great!

It is the size for credit card. It's built-in cord is about 2 inches as long perfect. I use this almost every day because my cell phone battery is weak. It charges my phone very fast

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!
