Portable Charger 38800mAh,LCD Display Power Bank,5 USB Outputs Battery Pack Backup,USB-C in&out Dual Input Phone Charging Compatible with iPhone 16/15/14 Pro,Android Samsung Galaxy Pixel Nexus-Green

No BS ReviewI bought this because of its low power output. If you're looking for a fast charger, this is NOT it—don’t expect that.After 24 hours, I was ready to return it. First overnight charge? Only hit 25%. I checked the reviews and sure enough, tons of people were complaining about slow charging. Figured it was just a dud.But right before sending it back, I had a thought—maybe the issue wasn’t the device but the charger I was using. For context, I’d plugged it into a 140W Apple charger (yes, the beast I use for my MacBook Pro). Kinda overkill.Guess what? It woke up. Charged faster than I thought was possible for a device like this.Now 5 days in, still holding charge like a champ.Pros:Reliable once paired with a decent chargerExcellent battery retentionHonest power output (no fake high-wattage promises)Cons:HeavyNot for fast charging unless you feed it wellMisleading if you don’t understand its charging needsBottom line: If you use the right charger (doesn’t have to be 140W—40W might already be plenty), this thing performs way better than expected. Just don’t blame it if you’re pairing it with a weak wall brick.

First off, it's a big battery. It's heavy and bulky. Can you carry it around? Sure. It's a bit large but fits in a pocket or hoodie pocket just fine. Definitely wouldn't be comfortable lugging it around for a hike but fits in a backpack fine as well.People saying "not convenient for hiking" yeah? No duh, why would you bring this hiking. Firstly, you're hiking, you probably don't have internet to begin with, so your battery shouldn't be dying that fast anyway, and second, why would you NEED a capacity this high for hiking, bring a smaller more convenient battery pack. Keep it in your backpack. Don't complain about the size when it's quite obvious it's going to be large and bulky. Durr.For my opinion. It's a good battery, it hold a humongous charge that lasts days. I see this as being perfect for road trips where you don't have to worry about holding it, just sit it in a cup holder or something and let it charge.No duh it takes a long time to re-charge it's 38k mAh. BUT it's not even that long. I saw reviews of people saying it takes FOREVER but never gave an actual time of charging. I charged it from dead and it took maybe 3-4 hours. Which is REASONABLE for 38 THOUSAND mAh!!!! Obviously it's going to take long to charge.[EDIT]: the product is not advertised to fast charge, but you can get it to fast charge by using a higher capacity wire. The wire provided with the pack will not fast charge due to its limitations but you can buy a higher capacity charging wire for a few bucks here on Amazon. After using the new wire for a few days it fast charges just like the original plug that came with my phone. So I recommend buying a fast charging wire if you don't want to wait 8hrs to charge your phone.TL;DR It's big and bulky and not comfortable to lug around in a pocket, but it holds charge for days with multiple uses, it takes a bit to re-charge but it's a large capacity so be patient. It does the job and charges the phone in reasonable amount of time. It isn't advertised as a fast charging device, but for the price compared to other brands it's good at what it does. And what it does is charge your device.

Out of the box impressions are -It’s slightly smaller in length and width than my iPhone 15 Pro Max in an Otterbox Defender case, and just over twice as thick. My unscientific analysis (picking them up with my hands) has this power bank weighing in about twice as heavy as the phone.… Yeah, not something you’ll be carrying around in your jeans pocket for sure, but it’ll be absolutely great to fit into a backpack. I tried it in my he-man style fanny pack and with this battery, phone, wallet, and a couple of other things in there the side pack does get a wee bit heavy.Oh, uh, the instructions were written by an individual who doesn’t use English as a first language, so read carefully. The only thing I really had to figure out for myself is that you click the side button twice to turn it off … I think. 😁I first charged it to 100% as recommended. Out of the box my unit was at 41%. It DOES charge slowly, but I like to use lower-wattage (5w?) older Apple charging bricks to lessen the long term ‘stress’ on all my batteries during charging cycles. Anyway, it took about four or five hours to get to 100%, but, well, I wasn't watching it that closely …The test - the next morning I checked and it was at 100%, so I plugged in my iPhone 15 PMx using the included USB-A to USB-C cable (it’s quite short). My phone was at 42% and I watched the charging progress — and I was actively using my phone while it was charging and/or I was listening to music on the phone.My very unscientific results has the phone charging about 3-4% for every 1% of the drain on the power bank. So that’s, what, about three full phone charges to one full power bank charge? And this is with a brand new unit. I’d plan on two full phone charges per 100% power bank charge to be safe.Slim and light she ain’t, but this thing is designed to be a strong and reliable backup source and I think it’s perfect for that. If I were to go camping for a few days in the bush I’d definitely take along a few of these things. Great price, too! What’s not to love?

The charger cord went bad and broke very quickly. It was also too short to be used reasonably, you'd have to set your phone down to let it charge off the battery if you want to use it. The cord also seemed to charge very slowly. After the included cord broke, I purchased a better, longer cord, and now the battery works very effectively. The battery size is about the same size as most phones, so it could be stowed in a decent size pocket, I would put mine in a pullover hoodie pocket to let my phone charge.
