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.

Last for days. Holds so much juice. It is heavy but that’s expected for the power. Charges at a decent speed to. Definitely value for money:

This thing is awesome, do be aware. It only has one USB-C in or out so one USB-C port in total I got mixed up and thought the lightning port was a USB-C. It is not so do be aware, but overall even beyond my mess up, this is a great product and it’s been going strong. Do be very aware that this thing takes forever to charge even with a power brick that can do 65 W it takes many hours. But it does have a great value for the money that you spend on it. It is very heavy though you could use it as a weapon, but please don’t. Overall, the heat is fine for a big giant battery pack. You will not burn yourself or others, but you could use it as a hand warmer.

The perfect portable power to power my mini PC. love this thing.

I love this charge block and still use it after a year or so. Only issue I have with it is after like 6 months or so the digital readout on it stop reading the remaining charge. Hooking a USB cable to both ports on it fixed it but seems to be doing it again. Besides that it's still working fine. It's big and heavy so you can charge allot.

Update: Had this product 3.5 months. Unit no longer turns on ac or usb ports. Screen does not turn on and does not charge. Your to contact Romoss through their website and glitch does not allow contact form to be sent. Can no longer recommend. Now a 1 star productI like the product. Form factor is good. I have been able to output 160 watts from the AC port. USB ports all work.However, display can be inaccurate and drop very quickly. This is common with some power banks of this style though.The biggest disappointment is the display. It only has percent battery. There is no power, voltage, wattage, time to charge / discharge, etc to show.If this power bank had an improved display this would be a 5 start product

This thing is great. I bought it back in may and it still holds charge well. It charges all of my devices (Phone, Laptop, Steam Deck, and portable screen to use dual screen setup with my laptop on travel) and charges them multiple times (May vary from person to person depending on device and capacity they wish to charge). One main note is the capacity, the 40,000 Mah is above what most airports and TSA allow without prior confirmation. If you intend to bring this battery with you, please call ahead to your airline and notify them you intend to bring it and have them make a note. When I arrived at the airport TSA immediately took me aside and looked up the rules for battery capacity and had a discussion with me. After notifying them I called my airline (United Airlines) and let them know I was bringing it, I was allowed to continue to my gate. I am really enjoying it so far and for the price its hard to beat.

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.
