Big but worth it

Reviewed in the United States 🇺🇸 on March 27, 2023

Thoroughly impressed after weeks of heavy use. 4 high speed out ports, charges with either USB type, sealed on 5 of the 6 sides so water resistant to an extent, and almost a full charge while I sleep. Only thing to keep in mind is the size, it's about the size of 2 galaxy notes ontop of each other with small cases on and about the same weight. Inconvenient if you're carrying it with no purse or pocket space but has no problem fitting in men's jeans back pockets with a galaxy note attached to it and has no problem sitting somewhere while it does its thing.

Certainly not the power capacity that is listed

Reviewed in the United States 🇺🇸 on March 22, 2023

This looks nice, functions like any normal battery pack. However the listed power cannot be correct. I get one phone charge on a device 3x thicker, and a bit longer and wider than my phone. ONE charge. So there is no way that this has 8.6x the capacity that the phone has (phone has 4500mah, this is listed at 38,800mah) as proven by the single charge capacity. Even if it was operating at only 75% efficiency I would get 6 charges.

So this is both false advertising and poor construction on the internal components. With this low of a capacity compared to the listed value I now have a major concern on how long I have until the battery is useless and the lithium bridge is formed.

I take this with me EVERYWHERE, I can charge my kindle, iPad pro, and my Samsung Galaxy 21 Ultra. I havent tried at the same time, inusually only need to do one at a time. If I use it down to 20% I can put it on my super fast charger and it will be charged when I get up the next morning. I really, really live this portable charger, leagues better than the one I had before. Also, the screen showing the battery percent is clear.

Proceed with caution if you decide to buy this. There’s a few cons and pros to this item

Reviewed in the United States 🇺🇸 on December 19, 2022

Color: BlackVerified Purchase

I bought power bank back in july because i had 3 upcoming vacations before the end of the year and waited till now to give it a full review. I was specifically looking for something that could charge anything. I decided to get this power bank because it takes usb-a and usb-c cables and since Apple is now only offering usb-c cables with its products, i thought this was perfect. I have a few good pointers and a few bad ones so here they are:
Pros:
- this charges my iphone pretty quickly. Within 20 mins it adds about 35% additional battery life
- it has 4 usb-a ports, and even while charging multiple devices at the same time, it still charges them all pretty quickly
- it charges my ipad pro. This is a big deal because not every power bank is able to charge an ipad pro
- the battery doesn’t deplete when not in use, which is great because there’s no charging power going to waste when nothing is connected
- it shuts off on its on after a few mins when not in use, so it saves it charge
- i get about 3 full charges for an iphone pro max

Cons:
- this power bank is really heavy. It’s extremely heavy. I’d say it’s heavier than a pound, which is an inconvenience when you are traveling light and are carrying a small purse. This will take the entire space
- this doesn’t charge usb-c so BEWARE! It’s such a shame because i bought it hoping that i would be able to use my usb-c charging cables and that is not the case. I find this very misleading from the seller as they advertise usb-c but they don’t tell you right off the bat that it only works to charge the power bank itself, but not to charge the actual devices. Big thumbs down for this.
- it takes about 12-14 hours to charge the power bank. I am not kidding, it literally takes that long to charge it to 100%. Multiple times I’ve left it charging overnight and the next day it’s barely at 65% there. It’s insane
- i bought this for $35, and throughout these couple of months I’ve sometimes seen it advertised for as low as $24, so it’s a con for me that i paid a third more than i could’ve paid for the exact same item.

In general, my experience has been ok, but this could definitely be a better product than what it currently is.

Wow, what a power source!

Reviewed in the United States 🇺🇸 on March 8, 2023

Color: BlackVerified Purchase

I bought this to power LED Christmas lights for our golf cart. I charged it per the instructions. That was back in December. I had a total of two “Dripping light strings” strung together on the cart. I used this as the only power source since it has four USB Out Ports. We ran those lights a couple of times in a golf cart parade IN the park and once on a couple mile jaunt around the neighborhood too. Those used only 2% of the power! I’ve since used it to recharge my iPhone a few times, my iPad a couple more and most recently my Beats Fit ear buds case and my Garmin Golf watch a couple times. It’s NOW down to 87%!!! At this rate I won’t need to recharge it until next Christmas lol!

Power for Days

Reviewed in the United States 🇺🇸 on March 30, 2023

Color: BlackVerified Purchase

This charger is great when going on vacation that does not have USB ports to charge my electronics. A bit heavy to carry in a purse, don't recommend that...LOL!! Charging time lasts for a few days without having to power the source. Throw in a backpack or suitcase and go knowing that your electronics have a good charging source.

This is good, but...

Reviewed in the United States 🇺🇸 on March 20, 2023

It charges slowly. I've been spoiled with rapid charges. There's no option for that on this battery. However, it does charge well. So, my lower review is for the length of time to charge.

Great Charging Power but Heavy for travel

Reviewed in the United States 🇺🇸 on February 28, 2023

Color: BlackVerified Purchase

Charger works great and quick, but it is too heavy for carrying in a purse or backpack for light travel trips. Weighs more than any other charger I've owned. Plus, there wasn't a pamphlet/warranty paper with the unit when received, therefore, unsure how the display works or if there is a battery to replace if and when the LED goes out. Unsure what to do if that happens.

A great little back up

Reviewed in the United States 🇺🇸 on March 19, 2023

This is an easy to use back battery supply it has plenty of connectivity. It has a small but still easy to read screen that tells you were the battery pack is on charge. It arrived with 22 percent charged it up at 100 percent. I look forward to getting many years of service from this

Resistant to any long cycling adventure

Reviewed in the United States 🇺🇸 on March 4, 2023

Color: BlackVerified Purchase

I bought it for my son who is a cyclist, a real one. He usually takes 2 to 3 months away cycling more than 2,000 miles abroad. This is the second time I buy this same power Bank brand to him. I don’t know much about it but it must be great for his trips. It’s kind of heavy in my opinion for a person who carries along 4 saddlebags on his bike to survive far from home. Anyway the product must be good.

Open Road

Reviewed in the United States 🇺🇸 on January 15, 2023

Color: BlackVerified Purchase

As an avid cyclist, averaging 20 miles a day, this was a perfect addition to my ride, keeping my GoPro and phone charged; even in the cold weather. Holds a charge well too, have gone 6 rides already and still have over 45% battery life left. Another plus is the power display, it let's me know how long I have left to go.

Update 02-20-2023 -- I charged this battery over 5 weeks ago and have road multiple rides while charging my GoPro and my cellphone and as you can see by the attached picture it still has 26% capacity. I keep it in my bikes saddlebag in the garage (where it is cold) and it still holds the charge. This is by far the best battery pack I have purchased for this purpose.
