Customers say
Customers praise the power bank's compact size, describing it as smaller than a deck of cards, and appreciate its functionality, noting it works amazingly fast and is reliable. Customers disagree on the weight, with some finding it light while others wish it was lighter, and longevity is also mixed, with some reporting it holds charge for months while others say it dies quickly.
Small and charges fast charging Great quality an plenty of ports very useful the battery life is enough for long trips and power outages pretty lightweight too and using the phone stand is awesome I dont need to put it on a bottle of hot sauce anymore Read more
This extra battery comes with a storage pouch and short cable, can recharge your phone twice before draining and it’s easy to take on a long hike or trip. I’ve had it for about a year and take it everywhere. It’s a little heavier than your phone but small enough to fit in your pocket. LED panel lets you know it’s working and how much charge is left.

I bought this power bank back in February 2024 and it’s been perfect for everyday use. It gives me two full charges on my iPhone 16, which is exactly what I need during the day. I actually have another power bank that I use for travel — it gives me 3 to 4 full charges, but it's way too heavy to carry around in my purse every day. That’s why I keep this one just for daily use, and it’s been great. It’s compact, has a bit of weight to it (which actually makes it feel high quality — not like cheap plastic), and it even comes with its own pouch. I always keep the cables inside the pouch, so everything stays together. So far, no issues at all. It’s reliable, has saved me more than once, and I definitely recommend it. Solid 5 stars. If anyone’s curious about the travel one (the 3-4 charge one), I can share that too — it works great, just heavier: J2621 Power Bank Portable Charger,20000mAh 45W PD3.0 QC 4.0 Fast Charging Battery Pack with LED Display,2 USB-C,2 USB-A for iPhone 15 16, MacBook Read more
Bought five of these power banks to donate to tornado relief drive. Excellent price, has a display with percent charge, light and small; would probably travel well. I was surprised that three of the five banks arrived with zero charge. I don't know if this bodes badly for the future owners; I hope not. It seems odd since five of the larger form factor banks arrived with the expected 50% charge, and I've bought this brand before: that power bank also arrived with a 50% charge. So I slow (USB-A) charged them with the included cable. It's supposed to be bad for Li ion batteries to discharge fully, so some concerns there. I would love to do a long-term update, but these, like the larger ones with a built in flashlight, will go to people in difficult, temporary living situations. Read more
I currently own about 10 of these, and they are hands down the best portable battery banks I’ve used so far. One of my favorite features is the visual percentage display, which lets you instantly see how much battery life is left—no guessing. Each unit is 10,000mAh, which is the sweet spot: high capacity without becoming bulky. For context, higher mAh means more charge. Most power banks top out around 10,000mAh before they get too large to carry comfortably, and these stay impressively compact. They can charge an iPhone Pro Max multiple times before needing to be recharged. I actually use these instead of wall outlets. I rotate them constantly, so I rarely plug devices directly into the wall—only the power banks themselves. It’s a system that’s worked incredibly well for me. Pros: Excellent 10,000mAh capacity without bulk Clear battery percentage display (huge plus) Very compact and portable Charges a phone multiple times per cycle No battery swelling after nearly a year of use USB-C and standard USB charging supported All ports are interchangeable for input/output Feels well-built and reliable Great long-term performance and durability Cons: Honestly, none so far based on extended use Overall Verdict: I’ve gone through many battery banks over the years, and these are easily the best I’ve owned. The size, capacity, durability, and usability are exactly what I want, and the fact that I haven’t had to replace a single one yet says a lot. I’ll continue buying these until I find something better—and that hasn’t happened yet. The reviews speak for themselves, and I couldn’t recommend these more. Read more
This little charger packs a punch! I wanted something I could take on a weekend camping trip and this charger was perfect. It charged my phone the entire weekend without running out of battery! It’s a little bit heavy, but not unusually so, and still small enough to throw in a small purse. The digital screen that tells me the % of charge left is a nice touch! It brought me a lot of peace of mind throughout my whole trip! Read more
