ROMOSSPower 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 am surprised to see that I've purchased this one in 2022. We are 2025 now and it is still running very well. There is a minor issue with it: If left charged for long time (over a month) the capacity 100% on the screen is not real. It would drop to 40% before shutting down. Once charged again, it will maintain the 100% real capacity.I didn't do scientific testing (I have the tools) but in general it never disappointed me. Many time using it without any issues.It has several charging ports with the option to bypass the low current charging time-out (for small devices). the screen is easy to read. Bright! With very useful information: Voltage, Capacity, Current... The size is a bit on the big side but totally expected! it is a large capacity power bank.Charging it with capable power supply is also fast! Sturdy build quality. Not dropped yet but it is indeed a solid brick when held. Still, portable! and capable of running and charging several devices at the same time. It has the UPS feature where it bypass power when being charged. I like this option.Easy to use. Nothing complicated here.

I purchased this a few years ago for when I go travelling and need a reliable powerbank for my devices, and this still does the job excellently! The fact that it has multiple USB Ports helps out immensely, and can take a USB C to fast-charge it is even better. I ordered the non-LED design, as the LED design wasn't an option then, but this is still a purchase I would recommend, especially since 30,000 mAH is plenty for keeping the average mobile phone powered up, Some might complain about the weight, but if you wanted a light battery, you'd be lucky if it could store enough power to charge your phone even halfway..

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.

Great power bank. Once you charge it, it keeps a charge for quite some time. I bring this with me fully charged when traveling and sometimes recharge it while on a trip. You can charge a phone and Ipad and it does the trick. Sometimes I put it away and take it back out a few months later and there is still 50% charge still on it.

I put 4 but it's a 5

Very good product, value for money. Keep charge for couple days. The quality is very good. Just alittle heavy

I own 5 of these for my kids. They're great for charging multiple times.

Very nice, came a day early too!
