EnergyQC Power Bank, 20,000mAh 35W PD 3.0+QC 4.0 Fast Charging Portable Charger with Built-in Lightning & USB-C in&Out Cables, Battery Pack for iPhone 16/15/14 Series, Galaxy, iPad, AirPods, Black

I've only written a handful of reviews over the past 20 years on Amazon, but this item was worth it. I brought it on a trip to Asia with my family and we were able to charge multiple devices simultaneously throughout our trip. I actually just bought a second one because my 10 year old stepped on the USB-C connector while it was plugged in and broke off the metal part of the plug. It's not the manufacturer's fault. This thing is very sturdy, but of course it's not meant to be stepped on while plugged in. We would use this all day and the battery would never even go below 50%. I highly recommend it!

I have been using the EnergyQC Power Bank for a while now and it has been a great addition to my tech gadgets. The 20,000mAh capacity provides ample power to charge my devices multiple times. The built-in Lightning and USB-C cables make it so convenient to use without carrying extra cables. The fast charging capability is impressive and I can quickly top up my iPhone, iPad, and AirPods. The sleek white design is also a nice touch. Highly recommend this power bank for anyone looking for a reliable and convenient charging solution on the go!

I’m super impressed with this power bank! The 35W ultra-fast charging is no joke - my iPhone charges to over 50% in just half an hour. The 20,000mAh capacity easily lasts all day and more, which is perfect for travel or emergencies. I love the built-in cables - no more digging through my bag for cords—and being able to charge 4 devices at once is a game changer for family trips. The LED display is clear and super helpful to keep track of battery life. It’s powerful, compact, and thoughtfully designed. Totally worth it!

First of all, the instructions provide conflicting information. They explicitly state to use the battery pack prior to charging until the display reads zero. The instructions go on to state that the display may not work properly or accurately if you charge it before using. Later, the same instruction manual states in large, bold letters:*IMPORTANT SAFETY INSTRUCTIONS1. Please fully charge the power bank before the first use.So who knows which way to do it? How can you screw up something as simple as basic instructions on charging?I chose not to charge it prior to using it completely disregarding the IMPORTANT SAFETY INSTRUCTIONS. The display read 55% when I received it. I charged my S25 Ultra from 22% to 95% in just about an hour. That was really encouraging. I charged my wife's iPhone 16 from 39% to 70% in about 45 mins. The display on the power pack then read 27%.So, I hooked up my earbuds which were at 44%. An hour later they showed 49% and the display on the power pack still showed 27%. I left the earbuds attached and 3 hours later there was no change in either the earbuds power level or the displayed reading on the power pack. So much for having an accurate display.Not a great confidence builder that this thing is actually going to last. If they can't get something so simple as a charge level correct, what other corners did they cut?I charged the power pack to 100% but now I have no idea if that's even close to being accurate or not.It's a shame because I was excited after it charged my S25 so quickly. I thought this would be a product I could get behind but apparently not.***UPDATE: 8/1/2025***The seller contacted me regarding my experience with this product. After some discussion they offered to send a new power bank to me. I've received it and had the opportunity to use it for about a week now.This one appears to work quite well. The display seems to properly reflect the charge status of the power bank and it charges my devices exceptionally fast.The seller also clarified the unit should be fully charged to 100% prior to first use. I did that with the second unit.So far, so good. I'm hoping the first one was just defective and the second one will work for a long time.I've changed my rating (the seller never mentioned anything about that, unlike some others I've dealt with) to reflect how well the second unit works and to mention the excellent customer service provided by the seller.

This has come in so handy when we've been traveling this summer. It's really convenient that it has one cord for my daughters iPhone attached to it and a c type for my son's android. It keeps a charge for a long time and quickly charges our phones. There are also ports to plug in cords along with the cords that are attached to it. 10/10 would recommend!

The EnergyQC Power Bank is a total game changer when you’re out and about. The fast 35W charging is super impressive—my phone gets to over 50% in just half an hour. The 20,000mAh capacity easily lasts me a couple of days, and I love that it has built-in USB-C and Lightning cables—no more digging around for extra cords! The LED display is also a nice touch to keep track of battery life. Great for travel, busy days, or emergencies. Definitely worth it!

If you're unsure about getting this like I was, get it. Literally has been one of the best purchases I've made this year.It's a cute size, holds a ton of power and charges my Samsung galaxy 3 times to full power which is huge for me.Make sure you get a plug that can take in the electricity the power bank needs or it'll take forever to charge. My initial plug took 5-6 hours to get this to full capacity but I got the Anker Nano Charger, 47W 2 Port Compact Foldable GaN USB C Charger for iPhone 16/15, Galaxy, Pixel, Compatible with MagSafe (Blue) and my power bank now takes about an 1hr and 40 minutes to charge to 100% when I'm not using my phone while charging.Highly recommend :)

It works great, the only thing is that it takes a long time to charge it, but once charged you can have multiple charges for your devices and it is really fast!!
