ROMOSS 27,000mAh 65W USB-C Fast Charging Power Bank - Portable Laptop Charger for MacBook Pro, Dell XPS, Steam Deck | External Battery Pack for iPhone 15/14, iPad, Samsung Galaxy | Perfect for Travel, Work, and Outdoor Adventures

I purchased this right in the spring of 2020 and it’s still going strong! It’s literally charging my iPhone right now via usb- C.UPDATE 12/22/2022: I got another one!Amazon won't let me make two reviews, so I am updating my original review. I first purchased this battery bank on 03/09/2020 and now, nearly three years later, I saw that this was on a 40% off sale, so I HAD to jump on that. This battery has been dependable, reliable, consistent, steady, stable, trustworthy, steadfast, unwavering, and...... reliable haha.You can see two years of wear and tear between the two in my attached photos, and I am extremely pleased with this brand and the quality of this battery. I don't even charge my phone from the wall anymore. I just charge this battery and charge my phone from it. Having two now will make that very useful. Just one of these is enough to charge my iPhone 13 Pro Max 9 full times from dead with a little bit of power left, as my phone has a 4,352mAh battery. With the fast charging, I couldn't imagine needing a different one. The 60,000mAh ROMOSS model was very enticing, but this was 40% off so this one is the winner.I'm not at all affiliated with the seller or brand, I just want to share my surprisingly excellent experience with you all. This is the battery bank to have if you want some charging insurance through power outages or if you, like me, like to play full controller games on your phone (it's call of duty mobile for me) for hours and hour and hours on end and need a portable, convenient power bank. These guys charge at a rate of 18w (9v 2A) via usb C and at 10W via micro-USB. I always opt for fast charging, as a battery of this capacity takes quite a while to charge. It takes a solid 8-9 hours to fast charge these from dead to full, and around 13-14 hours if you don't have a USB C charger. They take days of use before they die, though. Now that I have two, that's a problem of the past. Just recently, my IMUTO 30,000mAh power bank stopped charging through its only input, so I'm glad to have found this one on a sale! I paid full price the first time around and I would have done it again too.Anyways, 10/10. Absolutely recommend. I've never had any issues whatsoever with mine in nearly three years. All of the ports still work, the capacity is undoubtedly lower because batteries aren't immortal, but it still keeps a very solid charge after hundreds of charge and discharge cycles. I can still charge my phone and Apple Watch around 8 times each, maybe a little bit less. So don't worry about whether or not it will continue to work for you!I will update this review again if ever necessary.
