"This power bank works perfectly with my ROG Ally. The 65W charging capability means I can use it without worrying about power drain. Definitely a great purchase!"

"I'm really glad I bought this power bank a couple of months ago! It has been a lifesaver during a recent power outage that lasted for days. I remember this was the only power bank I could find with such a high capacity for under $20. While the indicator is a bit old-school, I still love how fast it charges my devices. I can't pinpoint how many charges I've managed to get because I never let my devices run out, but it still had plenty of power left. I'm so impressed that I just bought another one for my dad!"

I carry it in my bag while traveling to make sure I don't miss any photo moments. It stows nicely, and I can easily charge my devices from my bag. I often use it on vacation when outlets are scarce. This battery charges multiple devices fairly quickly and I always recommend it to others!"

"I own four of these batteries now because they are that good! They hold a charge, charge quickly, and have simple indicator lights. I've never run out of power with them, even after heavy use.

Overall, it looks good enough to sit in my boardroom, and I can see my coworkers wanting to use it too!"

"I received this product a few days ago and I'm still testing its functionality. First impression: It's gorgeous with a clean design. The surface feels fine, though I wish it were a bit glossier. The display showing current charge level is a huge plus for me, as I need to know how long it will last. The blinking light feature indicates when it’s charging, which is really helpful. There are six different outlet sizes, so I can easily plug in various devices without needing adapters. However, I found it very heavy for a power bank—at least two or three pounds. While I prefer to use it stationary, it’s still worth the purchase."

"What do I think about this power bank? It's roughly the size of my Samsung S9, but twice as thick and heavier. It’s definitely worth its weight in power. I wouldn’t want to throw it in my backpack for a long trip, but for car camping or backyard use, it’s perfect. I estimate it could give me about seven or eight phone charges.

"I've had such a great experience with the Veetomx portable charger! It has multiple charging options and is lightweight, making it perfect for travel.
