Hi JudithP, We’re sorry to hear about your experience. If your phone keeps falling off, it may be due to case thickness or lack of MagSafe compatibility, which can weaken magnetic alignment. Also, the LED display shows battery level, but doesn’t indicate charging completion—so we understand how that could be unclear. 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

Hi GaryH, Thanks for sharing your thoughts. With a 5,000mAh capacity, this model is designed for quick top-ups rather than multiple full charges. If you're looking for longer-lasting power, we recommend considering higher-capacity options like the 10,000mAh or 30,000mAh models. --Energizer PowerPacks Service Team

One would think that a company known for batteries would make a claim about a batteries capacity and charging wattage that was accurate. Alas, that is not the case. I have several of these type of devices. My car, work, purse, and nightstand. I picked this up because I had a gift card. It's the worst and MOST EXPENSIVE one of these I own. The wireless charging overheats, it charges my device MAYBE 13% before going dead. Again, I own several of this type of device. This entire product is a lie! All of mine are the same specs. I have three phones. All different types. It fails on all of them. I thought maybe it just wasn't meant for Android, but even iPhones don't charge well on this. Save yourself the money and spend 15 on a charger from a different web site.
