ROMOSS Power Bank, 30,000mAh Portable Phone Charger with USB C 3 Outputs & 3 Inputs, External Battery Pack PD 18W with iPhone 15/14/13/12, iPad, Samsung Galaxy and More

I bought this power bank 5 years ago (almost to the day) and I'm still using it.Of course it's lost some of its capacity but it's retained enough of it that it's still worth carrying it around with me.It's still recharges just fine, holds its charge, and charges even my most finicky devices.One of these times I'm going to recharge it up to 100% and see how many times I can charge my phone with it just to make a more usable review, but for now I'll just say this thing has performed astonishingly well.

I got it couple days ago and I am still testing the functionality of it sohere is the first impression:Looks:Beautiful, very clean design.Feel of the surface:SURFACE -It feels okay to touch. I would prefer it to be bit more glossy as it is mattbut then the trade off is the fingerprints. I think it will attract the dirt bit more then glossy though butnothing much I worry about.Functionality:DISPLAY that displays the current charge level HUGE PLUS. It is a must for me in a bank to know what is the current level of charge so I can comfortably use as needed knowing how long it will last based on how much power is in it.. The display window is not available on all banks out there so to me those are entirely useless.BLINKING LIGHT - When you charge it from the power source, the digits of a current level blink like a pulse so this tells you that it is charging. When you unplug it from charging the digits go steady so you know it is in the charged mode as opposed to charging mode. This is good, in case you would not plug it correctly for charging, you would get steady numbers so you could know to fix the plugging and not waste many hours thinking it is charging while it would not. This is important as often this kind of device needs to be charged in rush for emergency use and you have limited time to charge so this is very good feature.LOTS OF SIZES of the little outlets or whathever the name.. those holes that you plug in your devices.It has six different sizes of holes to plug different type of cables. This is very good because on the go oftenyou came across some device with weird size of the cable end and you need adapter. This solves this.Most popular six plug holes are there.Considerations:It is VEEEEEEEEEERy heavy for a bank. It is heavy because it has a lot of juice stored comparing to the average one but heavy as heck. I don't have a scale to tell you but their specified half Kg.. I am not sure.. it feels at least two three pound brick. It is not a problem if you are using it locally and have it sitting on a desk , but if you intendto parade about town with this it can be taxing on your arms.If you are flying and throw it in the suitcase it won't make that much difference comparing to solution it provides but otherwise not an ideal to hop around town. When I say HEAVY I really man it. I would think that it does feel like an actual brick that you build house with. Maybe I am wrong but i lifted it and went.. whoo.. my hand dropped..I still think it is a worthy purchase especially for the stationary use.My primary use is not to charge devices on the go with it but rather to turn a devices that need USB charge into a portable devices that can be taken anyway, as some of my stuff needs to be plugged to the computer permanently if I want to use it, no way to charge those. And for those that CAN be charged, I plug to this puppy instead and I can use them away from normal source of charge without cables and such and they can operate for hours or days depending on usage without recharging since they just use energy constantly from this bank.I wish it was less heavy and less expensive.I also wish it had a flashlight in it, I did not know there are some with one.Otherwise instructions did not came with mine and so I had no idea how long will it charge itself..so that is also a s urprise, it takes HOURS not minutes as I in my ignorance was expecting it to.So it takes solid 5 .. 6 hours to fully charge.It holds charge well and others already specified how much and what you can run on it.It seems that little devices like iPhone and such do not drain it much and you can refill themmany times energy-wise but the big items like iPad will only give you few charges.It is best to ask before you buy and need for specific use and those who own it cantell you from experience.

The ROMOSS 30000mAh Power Bank PEA30 is an impressive product that is definitely worth owning. Its large capacity makes it perfect for powering up devices when you're on the go or when you need to have backup power available. One of the best things about this product is that it can live up to its claims. It delivers a ton of power, and it does so flawlessly.I've been using this power bank primarily to power up an RGB office chair, and it has worked flawlessly for that purpose. The chair can stay lit up without the need for a wall outlet, which is really convenient for an office chair with a cool RGB effect. I've also used it as a bucket to hold thunderbolts when I need power somewhere that power isn't readily available, and it has performed perfect in that regard as well.Another great feature of this power bank is the LCD screen that shows you exactly how much energy is left in the device. It's a simple, yet effective way to keep track of your power levels, and it's something that I find really useful. I don't need to look at blinking lights and assume it has 90% battery life versus 80%. It simply states "100" at full charge and starts counting down until it hits 0. That's good to know. It also displays AMPs and VOLTs with usage by pressing the button on the side.If I had to complain about anything with this product, it would be the instructions that were provided. They were lacking in detail from what I remember and didn't provide much guidance on how to use the device. However, it was pretty easy to figure out how to charge the power bank just by looking at the icons on the device. I didn't really try to study the instructions either so it could just have been me.I also found the black 6-inch USB C cable that comes with the product to be kind of subpar. It doesn't seem to carry a lot of energy, and when I tried to use it to fast charge my cell phone, the charging rates on my cellphone were really slow. Like really bad. It's better to invest in a better USB C 100 watt cable to get more energy into this product faster. I've included a decent cable in the links below that works good for transporting heavy power to whatever USB C you plug into it.That being said, I charged the power bank a few days ago and used it for some pictures of another Amazon product, and it lost no energy between uses and sitting idle. It seems to be pretty good at holding on to its charge without any issues. This gives me peace of mind knowing that if I need to grab it in a hurry, it'll be readily available with multiple days of phone charging before it's completely out of juice.I love owning the ROMOSS 30000mAh Power Bank PEA30. It's practical, well-built, and offers everything that I could ever want from a power bank. Its large capacity and reliable performance make it an excellent choice for anyone who needs a lot of power on the go. It's definitely a product that I would recommend to others who are looking for a high-quality power bank.Supplemental Items (USB C Cable that offers better charging):https://www.amazon.com/gp/product/B0B79QMZBY - Better USB C cable to charge with (100 watt)https://www.amazon.com/gp/product/B0BC1D2WGR - Connectors for USB C cable (recommended)Other items shown (RGB Rod powered by USB):https://www.amazon.com/gp/product/B099DLH3PD - RGB Rodhttps://www.amazon.com/gp/product/B07JZCNPNV - RGB Controller (requires item below)https://www.amazon.com/gp/product/B07GWMX3G3 - USB to SATA Power CableIf you liked the chair (Not recommended but it looks really cool put together):https://www.amazon.com/gp/product/B088LNF2N5 - Chair (poor quality & uncomfortable)https://www.amazon.com/gp/product/B09TKDYXTG - Bottom Chair Base (Recommended)https://www.amazon.com/gp/product/B09D3HRYFZ - Piston (Recommended)https://www.amazon.com/gp/product/B07BLRZTCY - Wheels (Not recommended - poor paint job)

Pretty good deal. Got on a sale. Please with the quality and features. Charges my samsung S21 pretty fast...I would say it takes about an hour or so to get to 100%. I can charge my phone several times before having to recharge the charger. It is big and heavy but it's meant to be something you cab charge devices several times. So no biggie. Now I just need to find a carrying case for it.

Worked for about 4 years used it bunch for the first year didn't use it that much afterwards. The batteries finally gave up, and expanded outside the shroud.
