Love these batteries. Wireless charging with magsafe is a great combination. Used frequently over the holidays and phones stayed charged

I saw it in store for good price and I purchased one for trial, and I am satisfied. It can charge my G Power 2025 in either wired or wireless (M logo should be at the center of circle). It can charge up to 2 times with wired mode (wireless disabled but you still can attach on the phone with supported case for convenience). Recommended but you need to have at least 60 watts short cable.

Hi mingkee, We're glad to hear you're satisfied with the Energizer Ultimate Lithium 10,000mAh Wireless Power Bank! It’s great that both wired and wireless charging worked well with your G Power 2025. You're absolutely right—the "M" logo marks the optimal wireless charging spot, and using a supported case makes alignment even easier. Just a quick note: while the power bank supports up to 37.5W total output, each port has its own limit—USB-C PD delivers up to 20W, and the wireless pad up to 15W. For best performance, using a high-quality short cable rated at 60W or higher is a smart move, especially for fast charging. Thanks for the thoughtful recommendation! --Energizer PowerPacks Service Team

Pretty handy, travel friendly battery pack. I can charge two phones in between recharging this unit. Train, plane or in office it works well. Go through TSA without issues.
If you need fast charging you should connect to the USB C. Be mindful changing ports, it need about a minute in-between to reassign a different port to a different job. If you are too fast you maybe disappointed that it has not charged your devise at the end of the day.

Gets hot and makes me nervous

The charger works okay with my iPhone 14 max pro, and it’s a good price point. It’s slower than my regular charger, but it’s not terrible. The magnet is strong—no problem there. The only thing that I really don’t like about it is that it gets quite hot when in use. To be on the safe side, I try not to use it on or near something that is combustible. And I wouldn’t leave it in a hot car, even if it wasn’t in use. The fact that it makes me nervous is a bit distressing, and I’m wondering if I should have gone with something a little more expensive but seemingly safer.

Hi Michelle, Thanks for your honest review. We're glad the charger works well with your iPhone and that the magnet holds strong—but we’re truly sorry the heat issue is making you feel uneasy. Portable chargers can warm up during use, especially when fast charging or wirelessly charging, but they should never get uncomfortably hot. Also, if you're using a thick phone case, it may cause poor contact with the wireless pad, leading to slower charging and more heat buildup. For safety and performance, we recommend using a thin, MagSafe-compatible case and avoiding use in high-temperature environments like a hot car. We take this issue very seriously and apologize for the problem you've experienced. We want to help resolve this for you. Please visit our support page at https://support.energizerpowerpacks.com/ and fill out the form so our team can provide you with support. --Energizer PowerPacks Service Team

I was hesitant to get this portable charger because of the mixed reviews online. I am glad i ignore the reviews and follow my gut feeling. This is a very good charger, it charges my phone real fast. I have no complaints. I was able to charge my phone and my earbuds at the same time. This is definitely a good buy.

The size is perfect, not too bulky and the wheith doest is not a problem. The magsafe is strong, is fast charging. its get warm if you are using your cellphone but nothing extreme, you can charge your airpods too and that's great and very useful. the indicators of charge could be better with a digital screen beacause just a lights indicators are vintage to me.
