After two years, I decided to get another one
I purchased this right in the spring of 2020 and itâs still going strong! Itâs literally charging my iPhone right now via usb- C.UPDATE 12/22/2022: I got another one!Amazon won’t let me make two reviews, so I am updating my original review. I first purchased this battery bank on 03/09/2020 and now, nearly three years later, I saw that this was on a 40% off sale, so I HAD to jump on that. This battery has been dependable, reliable, consistent, steady, stable, trustworthy, steadfast, unwavering, and…… reliable haha.You can see two years of wear and tear between the two in my attached photos, and I am extremely pleased with this brand and the quality of this battery. I don’t even charge my phone from the wall anymore. I just charge this battery and charge my phone from it. Having two now will make that very useful. Just one of these is enough to charge my iPhone 13 Pro Max 9 full times from dead with a little bit of power left, as my phone has a 4,352mAh battery. With the fast charging, I couldn’t imagine needing a different one. The 60,000mAh ROMOSS model was very enticing, but this was 40% off so this one is the winner.I’m not at all affiliated with the seller or brand, I just want to share my surprisingly excellent experience with you all. This is the battery bank to have if you want some charging insurance through power outages or if you, like me, like to play full controller games on your phone (it’s call of duty mobile for me) for hours and hour and hours on end and need a portable, convenient power bank. These guys charge at a rate of 18w (9v 2A) via usb C and at 10W via micro-USB. I always opt for fast charging, as a battery of this capacity takes quite a while to charge. It takes a solid 8-9 hours to fast charge these from dead to full, and around 13-14 hours if you don’t have a USB C charger. They take days of use before they die, though. Now that I have two, that’s a problem of the past. Just recently, my IMUTO 30,000mAh power bank stopped charging through its only input, so I’m glad to have found this one on a sale! I paid full price the first time around and I would have done it again too.Anyways, 10/10. Absolutely recommend. I’ve never had any issues whatsoever with mine in nearly three years. All of the ports still work, the capacity is undoubtedly lower because batteries aren’t immortal, but it still keeps a very solid charge after hundreds of charge and discharge cycles. I can still charge my phone and Apple Watch around 8 times each, maybe a little bit less. So don’t worry about whether or not it will continue to work for you!I will update this review again if ever necessary.

High capacity
This can easily charge my iPhone pro max maybe 8 times before needing to be recharged. It charges fast and the lcd display adds a nice touch. There are a lot of ports on this and itâs shaped like a small brick. Not sure how durable it is if dropped. Wish it came with a protective carry bag or something to protect it.

18 Watt Power Delivery (PD) is Accurate!
I bought this to power my Meta Quest 3 VR headset. I’ve been wanting something that truly allowed my headset to draw 18 Watts. This battery does just that! After a two-hour session on Automobilista 2 (racing sim), My headset battery went from 100% to 98%, and the ROMOSS 40000mwh battery went from 100% to 85%. Are there cons? Well, it’s heavy, but what do you expect for 40000mwh battery? The charger it comes with charges fine, but seems slow. This isn’t a show stopper, because you can charge overnight, and use it practically all day. If it can handle a VR headset this well, I am sure it can handle pretty much any device you want to supply battery power. Cables are important. Do your research! I am using the Fasgear USB C to USB C Cable 10ft Right Angle 90 Degree 100W 5A PD.

Good overall solution when looking for large battery power capacity
This unit takes forever to charge (12 hours plus from a zero state) when using a standard usb connection. I haven’t had the opportunity to use a USB-C connector with more amperage, but still guessing something around 6-8 hours might be required. The first charge only showed 99%, no matter how long it sat charging. I used the 99% on a small fan we run in a cabin to circulate air. Ran the fan about 32 hours before it hit zero. That’s about 4x the smaller standard battery chargers I have around the house. It is heavy, so not great for travelling, but if you need a big charge, it may be worth it. Second charge on this unit showed 100%.Just a heads-up….this seems to stay on 100 or 99% for about half the battery life, then decreases somewhat rapidly from there. May just be my charger, but it’s hard to know how much charge you have once you start to use a full charge.

Great power packs
These two that I just received are in addition to their 30,000 mah that I received a few years ago. These are such a blessing to have so much stored power, until I am situated with amenities!!Romoss has been very dependable, durable and the oldest one is portable, in my mind. The new 40,000 is a bit larget, and the 60,000 is quite large, but I am thrilled to have the additional power into the future.

Very Happy With this Charger
While this thing is pretty bulky, it holds a ridiculous amount of charge for traveling. My wife and I went on vacation for 2 weeks and she sleeps with a white noise machine. Her side of the bed didn’t happen to have an outlet, so I just used this charger to power it and it worked flawlessly. I like the display that shows the USB voltage and current draw. Just a superb value.It is just the right size to put in my side pouch of my laptop bag, so it was a perfect companion for the entire trip.

DON’T BUY! and why can’t I change from 5 Star to one!?!?!!
I bought this item as an emergency backup battery. I’ve used it maybe nine times and it’s already malfunctioning/ not charging my Samsung S24 ultra. This thing is garbage!

TSA confiscated
Love this battery and took it on four flights but TSA finally confiscated it at the Philadelphia International Airport. They said United airline only allows 100w or less on plane. They said this battery needs to be checked into luggage. :/ really sucks cuz it powers my kids iPad for hours. Canât recommend for flights. :/

Die Powerbank ist wirklich gut. Leistung Satt!!!! Für Unterwegs in die Hosentasche stecken ist nicht 🙂 zu gross und zu zuschwer. aber für Rucksack oder zum Laden im Auto kein problem.

Vider entièrement la première fois.Il mâa fallut du temps. Reçue à 78% :o)Jâai mesuré les mAh utilisés pour sa charge complète 34224mAh. Je suppose que mon testeur a aussi sa tolérance⦠donc super satisfait de la véracité des informations annoncées. Câest la vérité.Je revaliderai la capacité lors de sa prochaine recharge.. il faudra du temps.usb-a et usb-c, (5-9-12V avec 3-2-1.5A)Sortie vérifiées.Double clic sur le bouton action permet de forcer le power on (empêche lâauto poweroff en cas de non ou trop basse consommation.Super je recommande.

La marca che non avevo mai sentito ho voluto testarlo . Dura davvero tanto ha un bel peso ma a me non importa per il mio utilizzo in casa carico anche 4 cell insieme in caso di mancata corrente e perfetto poi io lo ricarico con un pannello solare diventa energia green

En general muy satisfecho con el producto, ta un amplio margen de uso con la dashcam, con la que frecuentemente la uso en modo vigilancia o para cargar dispositivos.La única pega, que el tiempo para cargarla es muy elevado, eso que la estoy cargando con un cargador potente de 120 W.
