Customer Ratings & Reviews

I am absolutely impressed with this 20,000 mAh rechargeable battery. It has far exceeded my expectations! I was able to fully charge my phone four times, and it still has enough power left for an additional charge. The battery life is outstanding, and it’s perfect for long trips, busy days, or emergency use. Highly recommended for anyone looking for a reliable and high-capacity power bank. It’s worth every penny!

Works great. It charges faster then my super charger at home. It charged mine, my wife's, and my son's phones and still has some power. One con if you can call it a con is that it takes a long time to charge itself.

Absolutely love this portable charger. Definitely holds its charge, I am able to charge my IPhone 15 Pro Max about 4 times throughout the week.

Works great as advertised. It offers pass through charging, which is important. I use it to charge my tablet, which gives two full charges while using the tablet.

Full charge lasts me about 3 days,i use it frequently at work,and with the fast charge 2.0 ,my phone quickly charges

Its super faster charger blue circle. My samsung galaxy S24 ultra charge in 1 hour.

Work best it will charge 14 pro max 3 times & s24 ultra 1 time enough for advanced user

So my wife burned through an Anker 10Ah battery pack in less than a year, so I suggested replacing it with another Anker (this time without the wireless charging since she never used it). And, lo, that one was broken. It won't charge beyond 40% for some reason. So, I got this puppy for Christmas and she couldn't be happier. It's the largest battery pack we've purchased and it charged her Galaxy S21+ at least twice so far, without even putting a dent in the charge indicator after one complete charge. But the size will surprise you, no matter what it looks like in the photos. This is a chonky, slippery pack. Another reviewer suggested it has pass-through charging, which would be nice but we haven't tried it. And it does deliver quick charging... the S21+ only has SuperFast Charging 1 (15W) and this easily supplies that much. I have a feeling she'll get a lot more use out of this now, and hopefully it will last more than a year. I'm not a Samsung guy myself, but since that's what she's got I thought I'd give up my insistence on Anker and give her something she'd feel confident with. So far, we're BOTH impressed.

It does what its supposed to do, charges phone fast and can charge multiple devices at the same time. The material is good to touch. The only minor downside is that it's a bit bulky and heavy.

Excellent product. The high manufacturing quality is evident right out of the box. Superfast 45W charging is real. The only downside is the power bank's heaviness which is probably expected given its capacity.

Samsung’s 45W 20,000mAh Battery Pack delivers exactly what you'd expect—fast charging and dependable backup that keeps devices humming all day. It’s a bit on the bulky side, but that’s a fair trade-off for the solid build, generous capacity, and the brand’s trusted reliability. A must-have for frequent travelers or heavy users.

It is working very well. It charges fast. Wpuld buy another

My friend have Samsung powerbank and it lasted at least 7 yrs I dreamed of owning one as I travel a lot. I love it, very satisfied with my purchase Very good quality.

Grat battery for the price It come with the cable. Fast charge. It can handle my laptop my phone and. A jbl for extra power

Love the battery, i am able to charge my phone, tablet and computer several times while at work. Will definitely be getting another one in the future

Love that it has 3 ports to charge 3 different devices. Little heavy but that is expected with a 20,000 miliamp charger.

It has enough capacity for my OnePlus phone that I use for delivery driving my shop orders that I do currently for work, the 45 watts is more than enough for a swift and reliable charge-up especially in dire situations such as withering away with less than 5% who can you ask to be a better ally among broad band space than this. I previously used an Energizer one prior but I don't know about them, they seem pretty inconsistent but Ssmsung Portable Chargers now this is LIBERATION!!!

Loving this portable charger, gets about three full charges for my S23 Ultra with super fast charging!

Fast charging. A little heavy but does the job. Recharges in a timely manner

Samsung chargers i have purchase over other becuase of longevity and qualify i still have chargers from years ago thatcstill work well today this charger takes advantage of super fast Charge 2.0 i have been using from my S23 ULTRA and now may S25 ULTRA still works perfectly. I use my older power bricks as emergency reserve again still working from before Note 8
