Anker Nano Power Bank, Ultra-Slim 5,000mAh Magnetic Battery Pack, Qi2 Certified 15W Max Ultra-Fast MagSafe-Compatible Portable Charger, Ergonomic Design, for iPhone 16/15/14/13/12 Series OnlyClimatePartner certified

I just got the 16 Pro Max, and the magnet stay on there really good, like better then the previous Anker products that I have recently purchased on Amazon. I couldn’t believe how good it held on to my charging case during first use. Definitely one named can trust that hadn’t let me down. And I even get compliments on my Anker MagSafe Charger with the kickstand. I’m just another regular guy posting a review about what he’s enjoys. If I didn’t approve of this product, I will never post about it.

I just needed a battery to get me through the day of listening to music at work. Very slim with a strong magnet, fits in my cargo shorts pocket very well. Won’t fully charge phone from dead, but that wasn’t what it was bought for. Now I can ignore my coworkers all day long.😂

So small that I can’t believe its capacity.Works great and very slim with a strong magnet

This new model of powerbanks hold a tremendous amount of energy and the thinner size is perfect for traveling.

This magnetic power bank is convenient and easy to use. The magnetic attachment keeps my phone secure, and it's nice to have a portable charging option without cables. However, it does get a bit warm when charging, which makes me cautious about using it for extended periods.Additionally, the charging speed isn’t as fast as I’d hoped—my phone charges slower than when plugged directly into a fast wall charger. It’s fine for a backup, but not ideal for quick power-ups when I’m in a rush.Works well for light use, but could improve on heat management and charging speed.

Got this to charge my iPhone 15 on the go and have been happy with the charging rate, the look, the thinness and the smoothed edge (knowing you're going to be holding this in the palm of your hand so smooth > sharp corners). I didn't measure the charging rate, but I'm generally happy with the speed (added about 8% power in 5ish minutes) and I didn't notice any hotter temp as I normally feel when wirelessly charging. Been a big fan of Anker for a while now and am happy with this battery. For the price though, there are a number of other brands and batteries that are comparable in thinness (0.3" seems to be as thin as they come currently) that are less expensive.

I ordered this to extend the battery life on my iPhone without having to lug around my big power bank. This product ticked all the boxes for me. The fact that it Mag safes to the back of my phone and does not fall off all while giving me twice the battery life is amazing. I have another power bank that I use but I tend to leave it at home as its heavy and bulky. This power bank is slim, light, and efficient. Setting it up was easy and it attached almost instantly. I can get a second full battery charge off of this before it needs to be recharged which is all I truly need on a daily basis. It is definitely Anker as the quality is unmatched. I highly recommend this to anyone with an iPhone with a Mag safe that wanted to extend their battery life without adding much weight or bulk!

Anker always has the best name. Thier products are always top notch. I have the older 622 that’s double the thickness of this batter charger. It was fast and I was super happy with itThis model is rated at the same 5000 mA and it’s half as then. It feels good your hand. It’s rounded on the edges and it doesn’t add a lot of bulk to your phone.The unit chargers itself unplugged into a USB-C cord pretty quickHowever, one slapped on the back of my iPhone 16 Pro Max it charges at a rate of 4% for every 15 minutes. That’s only 16% battery charge per hour.My older 622 would charge to 80% much faster than that.Four stars for the fit and finish and quality of the unit. One star down because it does actually charge your phone, but it’s not as fast as I thought it would be.
