It is really heavy, but I take it in my backpack everywhere I need a backup battery, when it is fully charged, I can recharge my Samsung S20, 4 times, with no problem, taka a while to charge ( overnights), but it saved my life me many times, I used my phone a lot !

Battery is solid. It's a brick for sure but it doesn't take all that long to charge. Bout 10 hours but scaling that up from the smaller ones it's about 2 hours faster

While it may feel weird carrying around a brick in your backpack, it does do the job. Carries a large amount of elecricity, can check how much juice is left easy enough, and easy to charge.

I got this for a long weekend camping and this has been amazing. Great options for connecting multiple devices and I can attest to being able to provide multiple full charges. Definitely worth the price and good to bring on long road trips or anytime you’re away from power for extended periods.

It's not bad, but there's definitely better ones out there, it is bulky, we got it with the idea of just take one external battery with us for 2 phones, but the size and weight its probably too much, better off with 2 individual ones, plus it never charged the phone as fast as i thought

Was a gift for someone. Was told charging the power bank takes super long charge times. Like 12+hrs overnight. So charge way way in advance. A bit bulky but long life power supply.

Love this portable charger so far. Works well and it has 2 different connection options, so it’ll work with multiple charging cables. My only criticism is that it’s very heavy, but I realize that’s due to the size; I just didn’t know that would make a difference when I ordered it.

the thing has incredible battery life- i took it to disney and charged 5 phones from nearly 0-100% in the hot florida sun and not only did nothing overheat but the thing still had almost 20% charge left. best portable ive ever had

I wanted a portable battery that I could put in my pocket while traveling to charge my cell phone. This is NOT the battery I wanted. It is 6.25 inches long, 3.5 inches wide and and 1.5 inches thick. It weighs 1 pound, 6.7 ounces. You would need a very large pocket to carry it in. Out of the box, it was at 86% charged. I plugged it in and could never get it past 86% (i.e. to 100% ). I used it 4 days to charge approximately 20 - 25 hours of my cell phone use and the battery's charge went to 4%. After an hour of charging, the LED said that it was only at 8% charge. I have been charging it for 8 hours now and it is only at 38% charge. Although it comes with a USB charging cord, it DOES NOT come with an electrical outlet adapter for the USB cord. This is definitely not what I wanted and will never take it on a trip.

Great product, esp when purchased on sale! This is my second purchase of the same item. Heavier than expected as many reviews have mentioned, but it charges mobile devices several times over. I don’t leave home without it anymore. Pretty durable, too.

Lasts a very long time. I can charge my iPhone and iPad at the same time. It is chunky and heavy but that’s expected and also it takes a long a while to charge.

This battery pack is powerful and easily does double charging — but beware! It exceeds the 99 (or 100) watt maximum for carry on. Our unit was confiscated last week by Germany security check officers as we passed through Frankfurt. We had gotten it through prior checks in USA, Canada and Egypt with no problem, but the eagle-eyed German scanners flagged it. So… great for domestic use! Minus one star for that reason.

I needed a portable charger for an upcoming Disney trip and decided to go with this one. Best decision ever. I was at disney for 2 days and it charged 4 devices and still had about 20% of battery life left. It does take a while to charge the portable charger to 100% though. I was stuck at 86 %for the longest time but eventually I was able to get the portable charger to 100% by letting it charge over night. If you’re in need of portable charger I highly recommend this one.

The battery pack is great. This review would be a five star review, especially at this price point, but the weight of the battery pack, with its bulk, is an issue. Other than that, this is a great battery pack. The USB-c charging port is very fast. I take it hiking with me and I make sure to wrap it in a water proof container and I have had no issues.

Has lots of power to charge for days without running down. I charged many different devices on vacation for 4 people and on the 5th day I had to charge it back up. Its picky about the cord you use to connect, so high speed cables are prefered for faster charges. The cheaper ones work, just not as fast. It's a bit heavy so I used long cords & kept it in my backpack. It's well worth the money.

Great product charges all my devices Nintendo switch oled and lite along with the pro controller . And charges my phone. It does take a while to charge devices . It does take a long time to charge the battery bank more than 5hrs from 0. I’ve see. In the questions about unable to charge from usb c port . Mines charges my devices from usb c port and I also use it to charge the battery bank . Also use the lighting port to charge the battery bank . This thing has some weight to it so if weight is a concern get lower mah bank .

Love this! I spent 4 days in the hospital and never once had to worry about finding an outlet for my phone charger. I keep it charged and ready for whenever I don’t want to fret about there being and outlet. It’s bigger than most power packs I have had but well worth it. It’s also a bit of a brick but it works great. As we expect from a brand like Energizer. Oh I will say. I think it cycles through the 3 power banks, so you might think it is getting low but just wait for the next bank to kick in. It also takes a decent amount of time to charge but it’s a bigger power bank THAT LASTS.

This is a hefty USB charger that can charge several cell phones at once and it still has most of its charge. The downside would be taking several hours to charge if it's low. It's a bit heavy and might not be a good choice to keep in the purse for a phone emergency charge. This power bank would be great to take camping, hiking or keep on hand during an emergency situation such as a hurricane resulting in power outages.

I can charge my phone multiple times with this without recharging it. Its a little heavy but thats to be expected. As compact as something like this can be. Would buy again.

Battery lasts for DAYS between recharging. Seriously, it is a brick of a battery that charges several devices multiple times over multiple days before it runs out. Pro: your vacation will end before the battery does. Con: it is heavy, as should be expected for a battery with this much capacity (622g / 1.3 lbs). At a few airports I was stopped for a secondary check at airport screening because the battery appears so large on X-ray. You may want to take it out of your bag before going through screening.
