YKZ 100W Laptop Portable Charger 40000mAh, Waterproof Big Power Bank with Digital Display 5 Modes Lighting, USB C PD Battery Pack for Outdoor Camping Road Trips and Emergency Home Backup

This is a must have if you work in the field with electronic devices. I mainly use it for my laptop. It charged my HP laptop for 5% charge to 95% charge in about an hour. It used 50% of its battery. It allowed me to do my job without having to be tied to an electrical plug or converter in a vehicle! I highly recommend it. Also had a pretty bright flashlight. Only downfall is the flashlight button is way to push!

I’ll start what I don’t like1. The screen is too small for the data content2. The screen is difficult to read in daylight3. Flashlight is a waste of power4. Goofy flashlight on and off button5. Cheap plastic handleWhat I found exceed expectations1. Powered our Starlink Mini for over 4 hours2. Fast recharge3. Subjected to dust, unprotected trail torture in the inside of a side x side for 6 hours.4.The amount of data on a power supply is amazingwhen you are able to read it.5 When compared to the Jackery 100! this unit far exceeded the Jackery.6. Dependable

This thing is great, very high quality. My only complaint is it can be very slow to recharge, I have found that if you use two USB Cs to charge it charges twice as fast.

This one is the best. A nice light on it is good for set up on those cold winter mornings when it’s still dark during prep. Two thumbs up for sure.

While the screen did turn off at the beginning it never turns off now. It drains the battery and I have to continue to feed it like a starving animal. It says feed me please feed me because it’s so cute. So I there is no settings functions for the display reading the info sheet there is no one to call or email to get help. Since I’m out outside the 30 day window Amazon will let me return it but burn me for 25% of what I paid. I wanted to leave this review because if as screwed up as this is I’m going to keep it. The reason being I plan to keep it as a backup for vacations and times when we travel. I’m letting you know this quirky odd abnormality be cause if your like me you need to know these things before you buy. Plus maybe they will send me a new one for me if they read this comment. If they do I will give it 5 stars. Good luck and happy charging.

I gave 4 stars because I was expecting to "remember" the flash light setting. Other than that, excellent and better than other big competitors. If it is charged ~50%, supports the UPS function, charging during usage by a different device. The charging amperage should be greater than the depleting (usage).The flash light is good, I like it has multiple choices. I wish to have the switch in different place and to remember the state of the flashlight.

Does exactly what is expected

This tells you how to turn on the screen, turn on the flashlight, and what to do if you get water in it. That's it! Zero instructions on how to charge AKA How long to charge. How often to charge. If you should let it drain to zero before recharging, etc.Also, there is only a 2 ended USB C cord. No normal USB plug. There is a storm tomorrow and I literally can't charge the thing.
