2025 Newest Purple Wireless Portable Charger 5000mAh Power Bank - PD 15W Fast Charging for iPhone with MagSafe | Ultra-Slim Battery Pack for Travel, Work & Outdoor Activities

As another reviewer pointed out. Reviews are important. It would seem some have been left by individuals that never actually used this device. That is not on this products company, but on the individuals that do not respect the rules.That said, let me tell you about this device that I have used a number of times since receiving it.As a phone charger it is very convenient. It is nice and slim. The magnet is strong but it can shift around. This is best used while in your hand or set on a table, etc. It should not be used in an enclosed area like a pocket or purse for two reasons. 1. Overheating, it and your phone need to breath. Wireless charging generates a lot of heat. 2. It can shift off of alignment and stop charging your device.In terms of what it can do, it is rated at 5000mAh which is just slightly more than many phones have these days. That means, best case scenario it can charge your phone 1x. However, while the internal battery of this device may be rated at 5000mAh, you have to consider that ALL power banks have a conversion efficiency of 80-90%. That means that 10-20% or 500-1000mAh of that energy is lost in the transfer to your device. This is true for ALL power banks, so take 10-20% off the published mAh rating to determine it's usable energy. It's not deception, it's just how it works. So with that, we know the actual best case scenario is that this device can provide 4000-4500mAh to your phone. It successfully charged my phone's 4370mAh battery from 5% to it's software cap of 85% before being fully exhausted. Doing the math, it provided 3496mAh and had some to spare. That seems about right. So, it performed as it should.5 Stars
