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

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.

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.

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)

I own four of these now. Four. Because they are that good.No, they don't cook or clean or wash your car. They are a power brick. So not a lot to them.But, they hold a charge. They charge quickly. They have simple and easy indicator lights to help know how depleted they are (do you really an LCD display saying 76% vs 74%?).AND, and, and....for the best part: they don't run out of power! Okay, for those of you who can't truly think for yourselves, of course they can run out of power. What I mean is that they've never run out of power on me. Whatever I've needed them for, they had plenty of juice. If I forgot to recharge them after heavy use because they had only one "bar" of power left, well, they still had enough power to do whatever I needed them for.And what am I using them for? I guess pretty basic stuff. Work and family needs. Meaning charging a laptop or three. Charging up to five iPhones, well ... seven if our family brings the work phones along. Charging 5 iPads. Charging batteries for dSLR. Charging portable speakers. You name it. I bring them to the beach, a couple of them, cuz the kids forget to charge their phones or iPads overnight so they share one or two (I have three kids) on drive to the shore while wife uses another and maybe I have something charging in a third. And then we continue to use them at the beach and then on drive home. I use them to on long road trips also, so we're not all fighting for the one or two charge points in our car. I bring them for work to power a laptop or portable printer. I bring them on vacation. I bring them pretty anytime anywhere. And they just work.Like I said, never reached the bottom of these. At end of day (or the following day or the one after that...) I just recharge them and let them sit until the next need arises. Even for sitting for weeks or months (I do have four so they're not always used all the time...) they still hold a charge and are ready for action!Size wise they about 6.5"x1.25"x3.5". Im sure the fully accurate measurements are listed. But in real life they are the size of of 4 or 5 iPhone Pro Max stacked on top of one another. Literally the footprint of my phone, just thicker. Note that's the larger iPhone, but still. So, they can fit anywhere and go anywhere and charge whatever you throw at them.One thing, and you don't need to do this, but Amazon used to sell a silicone sleeve to fit over these. I buy those too. Red, black or white. No real need for them other than I like them. You can find the silicone sleeve elsewhere still, I know because I've bought them. No, you don't need the sleeve. But I like the extra grippy-ness and the way they look. Makes it a soft touch. Whatever, personal preference, but give those a try too if you find you like these like I know you will.
