Power-Bank-Portable-Phone-Charger - 40000mAh Power Bank PD30W Fast Charger Built-in 2 Detachable Output Cables, Flashlight and LED Display for iPhone and Android Phones and Most Electronic Devices

Do I love this portable power bank? YesBut am I IN love with it? Also yes.Can charge my phone multiple times between charging the bank itself. Works perfectly on my kid's ipads. I appreciate that they include the cords (tucked inside so they aren't flopping around) for the apple and samsung phones. I've also used a short cord of my own to connect and charge my bose headphones which use a microUSB.We bought this for a disney trip for use in the parks as well as the drive down the east coast, but I've gotten so much everyday use out of it, pre-trip. This would be great for use during a power loss or while camping, hiking, etc. There is a strong flashlight included which works well.Charging is fast (my headphones charged from 0 to 80% in about 15 minutes).I think its a great product and it was on an even deeper discount this week so I bought a second one! (Will give to family member)

I purchased and started using this charger around Aug 30th (2024). I charged it to 100% and began to test its power supply by leaving the flashlight on for 24 hours, didn't even lose 1%. Kept turning the flashlight pointing towards the ceiling - which lights up the bedroom nicely, for 5 hours every night. EVERY night!!! Also charged an iPhone from half charge to full. Today is October 6th and the battery is at 75%!!!Honestly, I've never had a power bank with such a small form factor and amazing power storage.That light though... Dang! I love that light!!!I have other chargers that feel heavier or bulkier, but this one is very slim by comparison of its power supply. Would strongly recommend getting this beauty for sure, well worth it!!!

Ideal for: people who travel, students, professionals who need to charge multiple devices without carrying extra cables. This portable charger is super good.

Works great and last long but bulky. I carry it in my car not convenient to put in pocket or heavy to put in purse. I use it for emergencies. LED flashlight is very good also . It helps that cables are connected to battery.

I got this as a gift for my b/f & he absolutely LOVES it. It charges things super fast and stays charged forever! It’s a bit bulkier than I had expected. The only thing that could make it better is if you could plug it directly into the wall to charge it.

*Revision*I placed a voltage meter between this device and a charging device. from 2% this took 13421mAH to get to 100%. This took several hours, it charged at a rate of 2.23AIt charges my phone at 9.11V using 1.67A - technically considered "fast charge" But it is drawing from a power well of 13280mAH - the device was claimed to be 40,000mAH - and is definately large enough to be 40,000mah.This proves beyond a doubt that this specific device i received was either used, or was falsely advertised by claiming the device holds 3x more energy.Still saying 0 stars, buyer beware, devices like this are those that wreck your expensive electronics and start on fire randomly. I will be sending this back, although i lack the box, i would rather not have it in the house.i left my phone connected to it over night, woke up, phone was at 15% this was at 0.ultra slow charge for other devices. The unit itself takes 24 hours to charge. Super heavy and bulky, if it didnt have lithium in it i would use it for an anchor, however it fails at even this task. 0 stars.

This thing is a life saver. Charges pretty quickly. Love that it has a type C & apple charger built in.

I've got a few PD (Power Delivery) tools to measure the input/output to chargers and I absolutely cannot get 15V or 30W out of this thing. Using several PD chargers, the best I get is 12V and 20W both input and output. I can get 5, 9, and 12V. When I program 15V I get an error.So far, it's not close to 40,000 maH. That would be 148 wH (3.7v * 40,000maH). I do see about 100wH when charging and maybe 88 wH charging my devices (Pixel phone and tablet).Edit: I decided to send it back and get a replacement. Only took 2 days so that was nice. However, as I'm charging it from 84%, it's still clamped at 12V and 19.5 Watts. I tried my programmable PD cable and it won't go to 15V. Looks exactly the same. Once I get to 100% I'll trying charging my phone and tablet again. I honestly don't expect to get more than 20,000maH.Edit2: I decided to send it back. Amazon needs to quit selling these 'high capacity' banks that don't even close to meet specifications.
