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 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.

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.

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.

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%

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 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 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.

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

I really loved this product, it has helped me a lot and it holds up to many loads.

Large portable charger that easily charges my Macbook Pro, iPad and iPhone. It's more substantial in size compared to my other portable battery chargers but really like the 3-port options. I would recommend!

Finally had an opportunity to use this and for given what I paid for it worth the value 100%. And it has a really long battery life even though it takes a while to charge worth the wait to have fully charged.

Its very great! Charges 2 iphones atleast 3-4 times with cent percent battery..

Great charges my phone/ipad quick would recommend this a gift for someone who travels

If you are constantly forgetting to charge your devices this is the power bank for you. This brick will charge your phone all week. Out odds so heavy duty they thought it would be a good idea to add a strap for easy carrying. 10/10 would recommend.

Great power bank. Enough power to share with the whole family

I use every time I’m out and it charged my phone faster than other chargers like this one

I’ve had this battery bank (Model UE30035C, SKU 6589871) for less than a year, and it’s already failed in a way that’s honestly concerning. The battery has swollen to the point that it’s separating from the housing and coming apart. This isn’t just normal wear and tear, it’s a safety hazard. A swollen lithium battery can rupture or catch fire, and this one is clearly no longer safe to use or even store indoors. It was used under normal conditions, no drops, no extreme heat, no misuse. For something that’s supposed to be reliable and portable, this kind of failure in under a year is unacceptable. I would not recommend this product. If you own one, I’d suggest checking it regularly for any signs of swelling and discontinuing use immediately if you notice anything like this

It has made life a lot easier on go, I use it all the time to keep the 360 cam in my motorcycle charged up. Durability & how quick it it charges the items so I don’t waste down time on my filming, can’t go wrong with that & it holds its how charge for a long time so there’s not need to constantly put it to charge.
