I like this charger a lot. I have taken it through TSA multiple times without any issues. It holds charge well and is able to charge my iphone 14 pro max multiple times. Like the wireless charging feature too.

"The best investment I've ever made! I purchased it two years ago, and it’s still working perfectly. It can fully charge my phone three times before the battery bank drops to half. Highly recommended!"

Same as the older model very heavy, the added wireless charging is a plus for phones or headphones that can charge wirelessly

Great to have on hand while on travel and I am not able to easily connect phone using a cable. I have only used this cordless and it charges my phone in a decent amount of time. It’s not the fastest but I can get 10% charge in a quick sitting. Fully charged in less than 1 hr.
Product is bulky and heavy. It fits in a small purse, but not in a pocket.
