I’ve been really impressed with how long this power bank can charge my devices. It easily keeps my phone powered through long days of travel or work without needing to recharge it often. The magnetic connection is strong and makes wireless charging simple and convenient, especially for phones with MagSafe. I also like the sleek metal design and the LED display that shows the remaining battery percentage, which makes it easy to know when it’s time to recharge. Overall, it’s a dependable and well-designed charger that provides plenty of power when I need it most.

I love the Energizer wireless chargers, I got another one for my husband. 10000mAh can be used to charge multiple times on a single charge. Very convenient and easy to use. No wire needed. It’s a nice and useful gift for the season.

Battery life could be better. Not exactly as advertised but does what it’s supposed to - charge. The MagSafe doesn’t have a strong hold or line up properly.

Hi Zach, We appreciate your feedback. Battery life can vary based on device type and usage, but we understand your concern. For the magnetic alignment and hold, ensure the phone case is MagSafe-compatible and free of metal or thick layers, as these can weaken the magnetic grip. If the issue persists or feels like a defect, please visit https://support.energizerpowerpacks.com/ for assistance with troubleshooting or replacement. --Energizer PowerPacks Service Team

Less than 10,000 mAh

The battery capacity appears to be under 10,000mAh, as it was able to fully charge a 5,000mAh phone but ran out before completing the charge of another 3,000mAh phone.

Hi aCustomer, We understand your concern. The 10,000mAh rating refers to the internal battery capacity, but actual usable power is lower due to energy loss during conversion and wireless charging, which can reduce efficiency by 20–30%. If you believe your unit is underperforming beyond normal limits, please contact us at https://support.energizerpowerpacks.com/ for assistance. --Energizer PowerPacks Service Team

Wireless charging works well with Galaxy phone on table or in my pocket. Some power banks have inflated capacity ratings so I tested it: Rated 5V 6000 mAh, actually delivered 5V 35.1 Wh > 7000 mAh.

Hi DavidK, That’s impressive testing! We’re glad to hear the wireless charging works well and that the actual delivered capacity exceeded expectations. Our ratings are based on nominal voltage, so your measured watt-hours confirm strong real-world performance. Thanks for sharing your experience—it’s great to know the product is meeting and even surpassing your needs. --Energizer PowerPacks Service Team

I first purchased a different unit by a generic brand with 5,000 mAh but decided its slimmer size was not enough of a trade off. So when this 10,000 mAh unit by Energizer went on sale (for even less than the 5,000 mAh one) I jumped on the chance. It is about double in physical size and heavier but in return I have the peace of mind I won't be short of charging power. The matte metalic body is nice to the touch and helps to dissipate heat. The magnet is strong enough to keep it from separating in spite of the mass.

Nice compact charger

Nice compact unit for recharging. To use the magnetic feature you must have a cell phone case with the magnetic ring. You can also use this charger with a cord and it operates just like any other charger. Charges a phone fairly fast--not sure how much time it took, but it would probably depend on your particular phone. After charging my phone it had plenty of charge left for another device. I like the size- would easily fit in a pocket and is slim.

Hi Gidget, we’re glad you like the compact design and magnetic feature. You’re absolutely right—the magnetic function works best with a MagSafe-compatible case, and using the USB-C cable is the fastest way to charge. The slim size makes it perfect for travel and pocket carry.

Best slim portable for the money

Got a good price for Black Friday sale. I like that it’s slim and light in weight. I have tried similar battery packs and they can make your phone heavy/bulky. No complaints yet. Maybe the battery life isn’t as good as it says. But definitely charges my phone faster. Maybe you can get 1.5 charges out of it which is not bad for the cost.

Originally I was going to get the slimmer version but has less capacity. So, I decided capacity was more important for me than looks and took this.
Also, I am using it as a charger in my vehicle. And, sometimes, it’s hard to “pair it” with a cell phone when it has a case.

Insaw thisnon sale and had to buy it. I commute usingpublic transportation for a few hours daily and this is the most convenient way yo get a charge and it is small enough to keep in any laptop accessory bag.
