Customer Ratings & Reviews

This is a very good portable charger that charges phones and tablets fast, and stays charged for a long time. It can also charge two items at once. It doesn’t get a 5 rating because it is a bit heavier than I thought it would be, and is uncomfortable carrying in your pocket. It works great with carry on luggage however.

EXCELLENT KEEPS A CHARGE AND CHARGES FAST. MY FRIEND LOST ELECTRIC THE NEXT DAY I BROUGHT THIS OUT TO HER AND SHE CHARGED HER PHONE, TABLET, AND RAN A LIGHT FOR A WHILE BEFORE IT RAN OUT OF JUICE.

I mean, price VS mAh was perfect. Great duability, clean readout anf fast charging. I didnt need to power a laptop off this thing so its perfect for the suitcase we use

This is my second Energizer brand charger and I love the upgrade to the display - it makes it much easier to use and check than the old illuminated dots way of indicating how much charge is left. I needed this portable charger because I have a podcast and have a couple of spots in the house where I can be comfortable and sit for multiple hours when editing it. The position is in the middle of the room and though my laptop charger reaches, I find that even long charging cords for my phone, AirPods and tablet are a pain. With this I can start a recording session with it charged and then plug my devices in as-needed and not mess up my flow. It's solid and full of power, which is what I need in that situation! And I can plug both the table and phone in at the same time. Recommend if you need a handy way to charge via USB - it's like having an actual outlet anywhere you need it!

I am a gig worker so I’m always using my phone. It’s kind of heavy but it lasts and it charges fast!

Purchased before my trip. I had great luck with it. It recharged my Apple phone more than 3 times before needing recharging. The percent of charge showing is a great feature. It does seem heavy.

It's exactly what I needed; it charges fast, and it's not as bulky as people say. Having a screen to see battery status is an excellent feature. It came precharged at 77%, and it took 30 minutes to recharge to 100%. On the first use of my Samsung Active 5 watch, which was drained out, it took 45 minutes to recharge to full, and the battery bank remained at 97%, so it's a beast battery bank.

Excellent battery supply, long lasting & quick charging, A little on the heavy side but is superior to other models I have purchased in the past.

Good quality, fast charging, not really heavy for this capacity

The 30K mAh unit exceeds the TSA requirements for travel, so buyer beware! The 20K mAh unit complies with TSA regulations and in addition has 2 USB-A & a high-speed USB-C port for charging. Easy to use, though would prefer to have had the instructions written in a larger font than 6pt as it was unreadable, so downloaded the manual on my computer. Not really necessary as it's easy to use, but I wanted to ensure that the USB-C port can be used for charging as well as for charging devices.

Awesome fast charging and huge battery capacity. This is the one if you love fast charging and use multiple times before it dies

I replaced an old battery bank that only had USB 2.0 for it's charging port - and I must say, this was quite the upgrade! Charging the device is MUCH faster, as well as fast charging capabilities for my phone/tablet from the battery itself. The LCD screen shows charging percentage and battery levels with a click of a button. I purchased this on sale, so the price couldn't be beat for the mAh provided!

I bought this to recharge some devices while camping. I found I could recharge my ipad 9th generation a couple times with it. I enjoy the digital display of the battery percentage. No complaints.

The product quality has been excellent so far. It consistently provides up to 5 full charges for my iPhone 13, demonstrating reliable performance and durability. Thanks BestBuy for providing such a quality products

Bought this charger to take on a recent cruise, as my phone is older and frequently loses it's charge quickly. The Energizer saved me many times on hikes and tours! Fit easily in my backpack - charges quickly and I even let others charge off of it, as it has two charging ports. I am very satisfied with my purchase.

Long life between charges and charges devices quickly.

I bought this to replace my old portable charger a couple months ago. This one charges devices quickly and can be used multiple times. It is great for when you're on the go and during roadtrips. I would definitely recommend it.

Charge lasts for a long time and the visual battery display functions as intended. Only thing is that it is a bit bulky so can be annoying to bring around without a bag or large pockets.

Battery capacity feels accurate - was able to my iPhone 15 Pro fully charge 3-4 times before needing to charge again. Charges fast. However, It is extremely bulky to the point I don’t want to keep it on me while on the go.

Works great! Has speed charging capabilities. I tested it with my chrome notebook as well and it was able to put up with it. My main use for it thus far is for my new oculus and it has worked great significantly increasing play time. Worth the purchase
