Customer Ratings & Reviews

This battery lasts quite a long time; I have it in my office chair for heating and massage. It lasts, with both heat and massage on, for over 3 hours. I really like the display of the battery charge, great idea. The only downsides I have noticed: it's pretty big and doesn't easily fit into the pocket on the chair, and it takes about 6 hours to fully charge from zero. Neither downside is so bad that I don't like the battery, though. I can make it fit, and I try to keep it on the charger when I get off of the chair, if it is below 20%. I have a heated stadium chair also, but this would be too big for the pocket on that one.

Massive battery pack that can carge my iphone 15 plus from less than 10% to full about 5 times. Great product. Also charges things like the nindendo switch quichly which usually take more watts than a normal chargers to charge at full speed. The only things to be aware of is this is heavy, and it does take a long time to charge the charger, even with a 65w laptop usbc charger it charges up slowly.

Decent power bank. It is heavy and bulky. I like the sturdy hand strap. Charged my cell phone 4 times from 0%. The charging speed is good. It took 20-30% of the battery each time I charged my phone. It used less battery when the phone was off while charging. I like the flashlight. It's useful. It took 5- 6 hrs to recharge. For comparison, I have a similar, more expensive Anker power bank that takes 8 hrs to recharge. I only get 3 phone charges from that one. The only issue is the size. Otherwise it's a good purchase.

this is honestly a great investment. Ive bought other portable chargers like anker and they do not last. This is a great battery. Lasts A LONG LONG TIME, very durable & charges multiple devices. 10/10 recommend

Bought this power bank after trying to find one that would have both enough power saved up to charge the Switch 2 multiple times for an upcoming hospital stay and also one that would be powerful enough that I could charge the Switch 2 and play it at the same time. My Phillips power bank I use for my iPhone 14 slowed the battery but wasn’t powerful enough to charge the Switch 2 as it played. However, in early testing, this one did. The indicator is great so I don’t have to rely on dots like my Phillips one. One downside is that it took seven hours to fully charge. But considering how much power it can hold and output it’s not really so much a downside, but an understanding. At a full 100% I was able to charge my Switch 2 fully, and the indicator on the power bank only dropped down to 74%. Judging by that, I should be able to charge this device three times over at least and have a mostly fourth charge. Again, it’s early but it’s looking promising enough for me to recommend this to new Switch 2 owners looking for a reliable power solution. The reason I’m only giving it four stars instead of five however is due to is size and weight. I know that it carries 30,000mAh but it’s really bulky and if you’re old enough to remember those thick Sony Watchmans or portable radios, then this is basically the size of those. You can get in your curling reps with this thing. I cannot even tell which is heavier: this power bank, and Xbox 360 power supply, or a Colecovision AC Adapter. They are all as equally heavy. And heaven forbid you decide on the 50,000mAh model! I got the 30,000mAh as it was at least triple what the one in the Belkin charging case is and that is supposed to charge the Switch 2 1.5 times over. With it’s $49.99 price tag and the 19.99 Game Traveler case, it’s the same cost as the Belkin one but with a much bigger power bank that you can rely on.

This power bank charges quickly for both input and output. The sizing of this power bank is reasonable for its charges. The build in strap is handy for carrying around. The digital monitor makes it clear to see how much juice is left.

This item is a bit heavy but works like a charm charging multiple devices. Yiu can charge up to 3 devices at once. 2 usb-c ports and and 1 usb-a for older devices/chargers. I do recommend for the price.

Somewhat large power bank. The battery percent display to really nice to have, as well as the green thunderbolt icon to indicate when a device is fast charging. I don't plan on ever traveling on an airplane with this as I'm unsure if I'd be able to get through TSA with a power bank over 27,000 mAh: "Airplane Power Bank Capacity Limits: Power banks with a capacity of up to 100Wh (approximately 27,000 mAh) are generally allowed in carry-on luggage without requiring any special approval. If the capacity falls between 100Wh and 160Wh, you typically need airline approval before bringing it on board. Power banks exceeding 160Wh are usually prohibited." Therefore, I'll be keeping this at home and used in cases of power outages.

Very good product. Allows for multiple charges of cell phone. Easy to use. The price was very competitive. The LCD display panel is very clear and helpful in telling user about the battery status.

I love how durable the item and i have been using it for over a year now! Fast charging and charged a phone 3-4 times. It can be a little bulky for some but I love it! Will get one for my husband!

Works as expected! My favorite part about it is that I am no longer stuck at a wall outlet trying to charge my phone while trying to use my phone. I would definitely recommend this product!

This thing is a brick! In a good way. Hefty, solidly built. Charges phone and tablet repeatedly almost as quickly as using AC power. Only consideration - make sure you’re willing to tote its size & weight. I’m glad I found it as an open box sale but think it’s worth full price too.

The Energizer Ultimate Lithium 30,000 mAh power bank is reliable and fast, with 30 W USB‑C charging and an LCD display. It can charge multiple devices at once, making it perfect for travel or everyday use.

If you're looking for a a charger that is light, look somewhere else. However, you're not going to get the charges that this thing has. I have another charger from Energizer and that has a USB cable as a strap, I wish this had that. It fast charges a Samsung S23 Ultra quickly though and would do about 6 charges.

I love my power bank. I’ve charged it once and is still going strong charging all my devices. Even though it’s a lil bulky I take it when I travel and charge on the road. It’s also very cheap for its quality.

I purchased the Energizer Ultimate Lithium 30,000 mAh Battery Charger because there has been one too many outages in my area. I like that it has an exact percentage meter that clearly tells you the amount of charge that is left in the battery charger. It has 3 ports so you can charge 3 devices at one time. This battery charger also has a carry strap for on the go. I recommend this battery charger because you can also charge devices on the go. Cell phones need to be charged all the time and imagine getting stuck some place and you can't make a call. Get yourself a battery charger!

This Battery pack is amazing!!! It has saved my life multiple times haha. I can now charge my devices anywhere and whenever I want

Great battery pack, i use it to charge my security cameras when I have bad weather for several days and my cameras need the sun, no worries now. I can charge 6 cameras and only drain the pack 15% . This is fast charging too or trickle plus i got it half off

Great device. Fast charging anywhere. On the go without an electrical wall outlet

I bought two of these, one for my daughter who went off to college, and one for around the house. Wife likes to lounge in the back yard with her electronics, but doesn't like to run power cords. This is a perfect fix, light weight and durable with good storage. Also, good for emergency back up in car.
