Portable Power Bank IEsafy 26800mAh PD 3.0, Type-C & Micro USB Inputs, 26800mAh Portable Charger USB-C Power Delivery (18W) Power Bank Fast Charge for iPhone 12 Pro Max, S10, Pixel 3, and More

This week recharge your device at near wall top speed. It also has a great life span.I also like the lighter weight and the slightly smaller package footprint. My only small complaint is there is times I wish for a second large usb port but I've been replacing cables to try to work around that small limitation.I might be picking up a few more of these prior to the next camping season to help with lighting and battery recharging.

Using a USB/USB-C tester, and after several deep charge/discharge cycles, it charged to about 15,000mAh, and discharged nearly the same; charging up my iPhone about 4 times: makes sense. What it does do well is fast charge and discharge at 18W. For that alone they are worth the price. Just expect ~45% of the advertised battery life. Added bonus: it can charge a device while being charged itself; useful when charging with a solar panel.

It charges very well, as if you were using an electrical outlet. I have used it on two devices at once (i-pad, I-phone) and it worked fine bringing the i-pad from 35% to 100% in less than an hour, while at the same time topping off the phone. Charging the battery unit itself is also fairly fast if you use a 2 amp charger instead of the 1 amp chargers widely used with phones. I use this unit in an airplane and there is now no limit to the length of flight. The battery keeps my I-pad at 100% during the entire flight. This is a must have for pilots. It essentially provides a completely separate electrical source.

I have had this product about 1 month now. First thing I did was charge it completely. It has seen little use but my grandsons has used it lightly to re-charge their electronics. It is still going strong and holding it's charge. It has not had heavy use but 1 month after charging it still is showing 3 out of 4 lights showing it's charged amount. So, what I can testify to is that it holds a charge over a month. I do not need things charged every day but when I do need to charge something I want the power supply to be there. It is with this project. I am pleased.

Comes with USB A to C and Micro USB cables. Charges quickly and has pass through (charges itself while charging a device). Compact size with some heft (~12oz).

This is your basic plain charger.I usually sped $30 more for the same charging power.However,I use them daily and 6 to 8bmonths is all I ever get out of them.So if this lasts 6 months,and I belive it will I spent around 3 dollars a month to keep my phone charged.Thats a pretty good deal I think.If it stops working before that I'll write another review.

Excellent product. I was able to charge my iPhone 12 Max pro 3 1/2 times before having to recharge. Very happy with product. Small enough to carry along with phone if needed.

Product works really good! I was disappointed that that it only has one usb A port. Can charge two devices at the same time, but one must have a usb c cord!
