Customer Ratings & Reviews

Easy to use. It recharges quickly, no more than 10 hours for a full charge. After that, you can charge your phone 3 to 4 times. I've used it for my computer a couple of times, and yes, it works perfectly. It also shows you a percentage of the remaining battery life.

PROS: Comes with a type c to c cord to charge up most android and iphone phones/tablets. Holds a charge pretty good so you shouldn't have to recharge it for a couple days at a time. charge up time is about 2 1/2 hours. CONS: No wireless feature and it's pretty big so can't fit in your pocket. at least not this one. They do make one that's smaller though.

[Employee of bestbuy] Quite a heavy battery but the longevity is so worth it, I've had this thing die on me maybe twice in the past few months that I've had it, and I've used it a multitude of times. It's size does occasionally get in the way but it's honestly negligible considering the battery life it provides. I'll never go back to the old power banks that don't show battery life on a screen with an actual number. No more 3-5 dots indicating battery life.

great gives me at least 4 full charges chargers quick and fast

This thing is a lifesaver. The high 20,000mAh capacity means I can charge my phone multiple times before it needs a refill. The USB-C and 3 ports make it really convenient, and the LCD screen is a nice touch—no more guessing how much battery is left which is to me a big feature. It’s fast, reliable, and perfect for travel or everyday use. Highly recommended from me!

The Energizer battery pack is a great value. It is not too heavy to carry with you. It has a long life.

The Energizer MAX 20,000mAh 15W USB-C 3-port Power Bank is a great portable and affordable power solution when extra power capacity is important. Weighing in at just under one pound, this battery is the perfect companion when away from a charging spots, as it should give you up to 72 hours of additional phone life, and up to 16 hours charging for large tablets. It ships pre-charged, so you can use it right out-of-the box. Mine had a 79% charge when I opened it up. The Energizer MAX has a large bright LCD display, which is easily readable even in full sunlight. It also includes a 3ft USB-C charging cable. The Energizer MAX has three ports, one USB-C In/Out, one additional USB-C and a USB-A port. The main USB-C port is rated 3A. I would definitely recommend this product.

It's heavy, it's perfect, and it charges my phone super fast. I love it

I couldn’t believe that I found a battery that - Price so affordable. - Extend my phone battery. - Faster charge for my phone.

Bought this on Black Friday , price was excellent, charges phone quickly and I like that it displays amount charge left in power bank. Only issue is it doesn’t have a built in cord. But for the price I paid it is a great value

I got this during the Black Friday Sale. I definitely recommend this, it can charge multiple devices and very handy especially during long trips!!!

This portable charger is a bit heavier than expected but charges multiple devices quickly. Provides 3 outputs to charge 3 devices at once and when the power bank is fully charged, able to use more than once.

Been using this battery for over 2 weeks. So far I’m happy w/ the purchase. It can charge 1 iPad ~2x or a cell phone 3x. It does need at least 10 hrs before the battery is charged to 100%.

A very good power bank, but could be improved. The battery capacity is probably what it says it is. But the charging is quite slow, at least with the cable provided. Also, the input and output USB3 ports are right next to each other and easy to confuse (there is writing to differentiate the two). Finally, I would have appreciated a pouch to put the thing in, along with the cable.

Works great holds charge for months if you dont use it

Best battery pack I ever bought. I recommend this product to everyone.

Overall, I enjoy the charger! The battery life is great and it's easy to travel with! I was a little worried about the weight of the battery, but it is surprisingly light. I also sometimes just carry it around while running errands and don't feel like I am carrying anything extra. I would definitely recommend for everyone.

Very good charger for the price, I’m enjoying its use so far, I’ve only paid $15 for this external battery by energizer

the iteam is fast charger and ita easy to use where ever u are

This is the second phone charger I've bought; I bought the first one 5 years ago and it's still working perfectly. I recommend this product; it's of excellent quality and the price is great at Best Buy.
