Energizer 30,000mAh Power Bank. Model #: UE30035C This Energizer power bank is exactly what I needed. The 30,000mAh battery capacity provides lots of extra power, sufficient to charge and recharge my cell phones and accessories quickly and efficiently on a single full charge. With one USB-A and two USB-C outputs, the power bank charges three devices at once. It comes with a four feet cable that can be plugged in the in-out port to charge the power bank from an exterior source, and can be used to charge a third devise using the power bank USB-A output. The LCD screen conveniently displays the battery level. Portability was not an issue for me. I was not seeking a smaller or lighter charger. Battery life, charging speed and overall performance were the pros that I was seeking and I definitely found them in this Energizer power bank. I highly recommend it. At the price that I got it using Best Buy's promotion and reward, this power bank was a steel. I couldn't get a better deal.

This is to review the Energizer 30,000 mah power bank. It’s an awesome charger on the go and it will charge everything you have before it runs out of energy! Some are having issues with it only charging to 80%. I had the same issue and figured it out. Put the power bank on a fast charging cord! The cord it comes with is NOT able to charge the device all the way. I use an apple lightning 20k brick & apple charger from insignia @ Best Buy and it charges it. It does take about 8-12 hours to charge, but I've never had to wait a whole day. It is the heaviest charger I’ve ever experienced, but it’s also got a ton more power than the normal ones so it’s gonna be heavier because it needs a better battery! Expect it to be heavy. If you don’t want it heavy, then get the Energizer 10,000 mah one and it’s just as reliable & light weight. Perfect charger! I’m extremely happy with this purchase and I got 3 of them for when the power goes out! Just remember to not use the black cord that it comes with, charge it on a lightning cord and you won’t have any issues. Also use a lightning cord to charge your items and not the black cord that comes with the item.

I got this power pack because my phone is older and won't stay charged. This works very well. It came ready to use and holds charge for a long time. I like that it shows how much charge is available on it when you plug your device into it. It is heavy but I don't carry it all the time so that's not a deal breaker. It charges my phone and has never gotten hot like some do. It stayed cool to the touch. This makes me feel like it is safe.

I am heading to a location soon where I won't have access to any electricity for over a week. That is exactly why I was looking for a power bank with LOT's of power. The Energizer 30,000 mAh product is just what I need. Pros: *substantial power. I have charged my phone several times, once from being almost completely dead, and I still have 70% left on this power bank. *Clear LED that shows you where the power level is. *Can power multiple units at the same time. Cons: Please be advised that this is NOT a small or light power bank. This won't be something you carry in your pocket. It is quite substantial. Summary: If you need something more portable, go with a smaller product, but if you will be away from electrical outlets for any length of time I highly recommend this very powerful unit.

The unit was already partially charged upon receipt. While charging it to full capacity, it would only reach 86%. Online research instructed to discharge the unit to 50% and upon doing so, it now reaches 100% charge! The unit has multiple outlets to charge more than 1 device simultaneously. I will be using this mostly for my phone and needed a power bank for times when there are extended power outages from hurricanes/storms here in Texas. The unit is heavy and not petite, BUT, when one needs power, this is great insurance to keep your device operational. If you are looking for a compact, lightweight power bank, this probably isn't for you. So far, I am pleased with my purchase.

Havent had it very long. Bought it to take with me on a trip. I was gone 8 days and it kept my phone watch and tablet fully charged the entire time. I was at the beach a few days so i wasnt using them all the time. But i am still impressed. For the price i feel it should be that good, and it didnt disappoint! With Heavy useage id guess about 4-5 days before it would be out of charge. I like the mutiple input/output ports it has, however it did take all night to recharge. Included in the photos are the charge\discharge information on the back of the decive for those interested.

It’s really good like I mean really good it charges ur phone in a matter of mins faster then ur original outlet and I really like it but when u do charge it just don’t use it at the same time for all that power going into ur phone will just overheat it bc ur using it at the same time I knew the bunny brand was good just not that good 100% recommended I just don’t recommend using it while using ur phone at the same time oo nd it does take really really really long to charge charge it overnight it’ll only be at 30%

This is a big charger. I wasn't expecting it to be so heavy but this does hold a long charge. I was able to charge 2 iphones for a few days and this still had about 30% battery left. This is great for long vacation.

This is officially my largest power bank. I wanted a power bank from Energizer for a while now. I like the little screen that displays the battery. It is a little bulky. I haven't had to charge it again since getting it, so I'm now sure how long it would take, but guessing since it's 30,000 it would take a while.

The Energizer battery pack is very simple to use. You can charge it with a micro USB, USB-C, or Apple charger. It outputs to up to two USB cords so you can charge two devices at once. The digital display on the battery pack clearly shows how much charge the battery pack has. It comes with a short USB to USB-C charging cord that was perfect for me since I have a Samsung Galaxy. The charger is about the same size as my Galaxy 9, and about twice as thick. Even though it's large, it is very effective. I would buy it again.

This multiple port charger allows me to charge my phone, kindle and gaming accessories when I am travelling. I am flying often and find that chargers on planes don't work usually. I needed something to take along so I could keep working while I am on the go. It charged rapidly, you have to use the "in" port for that, and allows you to charge multiple devices. Its bigger than a standard charger in the width (about 2X) but lasts longer. A great purchase!

This is a great battery. It last long but it should because it’s as large as a mini-tablet. I was able to charge multiple devices without a hitch. Note it takes a long time to charge so do it well before a trip.

So far excellent! Easy to use, lots of juice to charge devices! Haven’t needed it yet (knocks on wood) but I’ll update if any issues arise.

This thing is bulky. But it charges my phone multiple times on one charge, so its worth it. Only thing is it takes a solid 18ish hours to charge it back up. Comes with a nice charging cord, and a little handle if you need to carry it around. I've had it for maybe 2 weeks and no compaints so far. I got the open box one.

For my 30,000 mAh 15W, I am still working with this power bank and testing it out. It is a pretty heavy power bank. PRO: Charges my FitBit watch and iPhone pretty quick. Has multiple ports for devices Shuts off automatically when not charging a device CON: The weight (22.2 ounces...1.38 pounds) When down to 0%, took 3 consistent days to charge to 100%. I am not sure if there is a better way to charge it faster...working on that. When charging my FitBit watch, it constantly shuts down and I have to hit the side button to finish charging. It does come with a charging plug, but it is only about 11 inches long. I do like this charger and if you don't mind the weight, I do recommend this.

I’ve been extremely impressed with this Energizer 30,000mAh Power Bank. The large battery capacity easily keeps my phone, tablet, and accessories charged throughout the day without needing a recharge. The built-in USB-C cable is very convenient and eliminates the need to carry extra cords. I also appreciate the LCD display, which provides an accurate battery percentage at a glance. The charging speed is fast, performance is reliable, and the build quality feels durable and well-made. Whether traveling, working, or on the go, this power bank delivers dependable power when I need it most. I highly recommend this product to anyone looking for a high-capacity, easy-to-use portable charger. Excellent value and outstanding performance. 100% recommended! ★★★★★

Pro- a physical solid battery. No empty space. Largest battery in compact space vs others, 2 usb Out. Power % display Con- max output is 2amps, only comes with small USB C charging cable no wall plug. Would be better if had 3amp fast charging to device and came with wall plug.

This powerbank is powerful enough to charge four phones and can probably charge two tablets. Although it is not slim and sleek, it is not bulky and can fit into any ladies handbag. One good feature is that it does not get hot during recharging. With two output ports you can similtaneously charge your phone and tablet.

This portable charger is great! It’s a tad on the heavier size but still gets the job done. I am able to charge multiple devices at once and multiple times without having to recharge the actual charger. I have had previous portable chargers and nothing compares. It’s still small enough to travel with as well.

Easy to read display. Charged my galaxie quickly. Came almost fully charged.
