Great size and I love the wireless charging! This charger can charge my phone multiple times and I don’t have to remember the cords. Also fits in your hand nicely while charging.

Works great and charges very fast. Holds its battery. Could use a USB outlet in addition to a USB C but you get what you pay for. Good battery

Long Lasting and Reliable Power Bank

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.

Excellent power bank with a slim metal design and strong magnetic hold. Charges quickly, works perfectly with MagSafe, and the LED display is very helpful to track battery level. Compact enough to carry daily and feels premium. Highly recommended for iPhone users.

Works, but Feels Cheap and Disappointing Overall

I’ve been using this Energizer 10,000mAh Slim Metal Magnetic Power Bank with an iPhone 16 Pro Max. On paper it sounds great, but in real-world use it doesn’t quite live up to the spec sheet.
The main positive is that it can charge my 16 Pro Max about twice before the battery is fully drained, which is respectable for the size. It does technically do its job and provides both wired and magnetic charging options. When it’s charging, it’s doing what it’s supposed to do.
Unfortunately, that’s where the good news mostly ends. The build quality is a big letdown. With only light use, the back has already started to cave in slightly, and the exterior scratches very easily. For something labeled “metal,” it seems to have a surprisingly sensitive personality. Charging the power bank itself also takes a long time, so patience is required.
The magnetic connection is another weak point. It barely stays attached via MagSafe, and even small movements can cause it to shift or disconnect. Wireless charging works, but it feels slow and a bit unreliable compared to competing options.
Even at around $18, it’s hard to recommend. While spending about $40 more on a competitor is a big jump in price, the difference in quality and reliability is noticeable. When something just works, the extra cost feels worth it. This one does charge your phone, but that’s about it, and it doesn’t do it particularly well.
Three stars for basic functionality, but I wouldn’t buy it again.

Hi Damethagamer, I’m sorry the power bank hasn’t lived up to your expectations. It’s good to hear it can recharge your 16 Pro Max a couple of times, but the issues you described with the build quality, slow recharging, and weak magnetic attachment are definitely disappointing. Your detailed feedback on durability and MagSafe performance is very helpful, and we’ll be sharing it with our internal team for review.

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.

We’re thrilled you’re enjoying the Energizer wireless charger! The 10,000mAh capacity is perfect for multiple charges and the MagSafe feature makes it truly wire-free and convenient. Great choice for a seasonal gift—portable power always comes in handy!

This is a well-built charger-compact and fairly lightweight. I tested it by charging my Android phone from 10% to full, and it only used one out of the four bars on the indicator. That's impressive efficiency for a single charge cycle. Great for travel or everyday use. I recommend this to everyone!

It’s a cheap MagSafe battery pack that is nice to have in a pinch. Unfortunately, the MagSafe magnets are fairly weak and it pops off easily and the overall charging speed is fairly low.
