ROMOSS 60,000mAh Large Power Bank, High Capacity Portable Charger 22.5W USB C Fast Charging, Long Lasting External Battery Pack with 4 Outputs & 3 Inputs for iPad, iPhone, Samsung, Switch and More

After 3 years of use, this thing is still charging strong!Pros:-Multiple uses per full charge-Charge multiple devices at once-Visual display (Percent Remaining, Bolts, Amps)Cons:-Heavy but needed due to its Mah-Ports are flimsy (USB-C no longer works because the contact has separated with use-Takes a while to charge but amount of charges from device outweighs the time it takes-Amazon could not get me in touch with US customer service to solve. Would pay to repair.

The charger has multiple USB-A ports all QC rated and a USB-C, Lightning charger port AND a micro usb. The power bank can be charged with the USB-C or micro usb.1. Its a brick, and its a bit heavy. I use it in a travel trailer so family can charge up when were hanging out inside so I can spare my trailer batteries. The build quality is all metal - its sleek. This will be great to take on my boat too.On compatible laptops you can power the laptop from the lightning or USB-C port.All I can say is it lasts forever (it seems like) running my laptop off it just browsing the web or watching youtube I got over 3 days of power from the bank. I intentionally killed it when I first got it just charging everything and running everything off it and the thing just slowly drains. It took forever to kill it. Equally it take a lon time to charge but it does support fast charging (9v-12v) from compatible chargers like from Samsung. The best I could do was 27 watts of charging from my best charger.I like it. But its nothing you can easily throw in a backpack, weighs like 4 lbs. Great for camping. If your not going to use it for a long time, discharge it to about 60% so the battery dosent burn out. You dont want to store these fully charged.

I put this on my end table or coffee table while I’m on my iPad or phone, it charges so fast that it’s (in one word AMAZING!!) I tell my friends that I can power up a small island. I absolutely love this thing and the value for the money is perfect. It weighs a little over 3lbs. The durability of this thing is unmatched. Great size and tons of power.

I got this to charge my body cam at work and this has been perfect for it. Charge last several charges of the camera. It takes a while to charge back up but it’s worth it

I bought this right before a 2 week back country trip. It charged my phone, Garmin InReach, iPad, bluetooth speakers. It worked well.Pros:It has a LOT of battery. I charged it up before the trip and STILL have not been able to drain it. I am trying to fully drain it for the process listed in CONS. It lasted the whole trip and I have been charging my iPad and phone with it since then trying to drain it. It has plenty of USB outputs, 3 USB A and 1 USB C and it charges fast with all ports. It is very energy dense. It is like a brick both in size and weight. It has a lot of battery for the size. My S20 Ultra was charged about 75% last night and it took 4% of the battery to fill it and keep it full overnight. I like the LED display that shows output current and battery percentage left. It held up to camping for 2 weeks just fine.CONS:The instructions say that you need to fully drain the battery and then fully charge it in one cycle to train the BMS so you can get the full battery life. This should not be left to the end user to do. The battery came with 81% on it, which I was not able to drain before leaving. The instructions are limited and I do not know exactly what the side button does. Does it turn it on? It cycles the display, does this change functionality? It does not appear to like low draw devices. It will turn on then back off when using my low draw LED light string and it does not appear to matter which USB port it is in. Could the side button help? The case is has a satin type finish that will scratch, kind of like the Lenovo laptops. I don't care as I am after functionality first, but someone might.All in all, I am happy with this and it will serve my needs well. It has been really good so far and I would recommend this. I will continue to test and do some math to verify capacity. Many are listed in Mah with a nominal voltage of 3.7 (internal battery voltage) and not charging capacity from USB at 5v+. I cannot verify either way yet. I still need to complete the drain and refill process. Either way, it is a really good pack so far and I am glad that I bought it.

Wouldn't reccomend. Charges to 100% but when you plug something in it just keeps shutting off. Stays on for about 30 seconds. Not good for charging anything. Go somewhere else like a well known brand such as Anker or Urgreen.

My job requires me to be out in the woods camping for two weeks at a time and every necessity to be packed into one bag. I knew I’d need a large battery and this is the exact solution I was looking for. Other portable batteries that carry this much mAh normally look like a mini generator and I needed to be space-conscious which worked perfectly as it’s about the same size and weight as a literal brick. I didn’t need to charge it until about 10 days which is quite the feat for how many times I’d have to charge my phone, headlamp, devices, etc. It charges relatively fast for how large it is, and the only drawback I’d say is one of its best features: it’s size. If you’re planning on bringing this in your daily bag and hiking around or lugging it around everywhere you go, be aware it’s still pretty big and pretty heavy, but if you’re gonna have this at your campsite and use it when you return or have it in an area where you don’t have to always have it on-hand then this is perfect. Once again it’s small for how much power it can hold but still it’s a massive battery and with that comes weight and size. It does the job perfectly for me and I’d highly recommend spending the few extra bucks to buy this absolute unit of a machine.
