    Works great

    The different types of USB ports are useful, and the ability to charge the battery via USB-C or USB-A is great. I've charged my phone twice and it hasn't died yet. My phone hasn't been completely drained, but I think this battery is charging me enough. The only downside is that it's a little heavy, but fits nicely in your back pocket. If it's on sale and you need it, buy it. And a spare battery is always at hand. You don't realize you need it until you have it and your phone dies

    Great power bank

    My first portable power bank. It came with an 80 percent charge and took very little time to charge it to 100%. Let it set for 2 weeks and still had 100% charge. Connected the power bank to my MP3 that was showing empty, and it charged in a few short minutes, much faster than using dedicated power outlets. It only used 2% of the power bank to charge. Very impressive!

    Light weight and enough charge.

    The energizer battery pack is enough for 1 full charge and a half for my iPhone 14 Pro Max. The weight is about the same weight as my phone. It’s perfect for my teenager and for me traveling out of town.

    Great charger but could be better.

    This device is capable of charging two cell phones. The only negative comment I have is the cords are not built in. On day two of our disney trip I remembered the battery charger but did not grab the cord out of the plug. Needless to say it was worthless without a cord. If it were capable of wireless charging or had built in cords it would be better. Also, it is heavy.
