Macbook Charge Only To 80

Only problem is that I should of bought the XK-80.

Love this monitor! Can charge my macbook. I want to buy another one.

Been using Cokin since the 80'sor 90's and they still work really well. Light weight, strong and work well. Only reason I got another one of these babies, is because my last one broke after badly packing them. Having said that it mended just fine with some Gorilla Super Glue! So now I have two and can use on both cameras!

NOT ONLY does the Watson re-charge the batteries, but it also shows you how close each battery is to Full Charge. One can also discharge the batts in order to perform, what some say is, a more complete re-charge. Soon, I will buy another.

Great usb cable to charge your MacBook Pro

Everything you need in one box to charge your MacBook in pretty much every country you want to visit.

Battery was received quickly with excellent packaging. It installed easily, having about 80% charge present. It charged to 100% quickly after installation. Very satisfied. I have another UPS just like this one, so I may be ordering another battery soon.

I thought about building something like this a few times before I got my iPhone. It steps up the voltage so power can be transferred which takes some power to do that. It has an efficient design so it doesn’t use much power for itself when sourcing power. You have to make sure it’s turnt off when not being used or it might not turn itself off. I seldom charge my iPhone above 80%. I’m sure it would charge it at least twice from 20% to 80%. I used it to charge both my AirPods and keypad which have small, delicate batteries and felt safe about them even though I manually turn the charge cycle off. It’s handy to be able to charge and use both one or two batteries at the same time. It looks well built and with good quality parts so it should last long. I liked it rate off so I bought two more. Now I can get more out of my batteries by inputting and outputting power at the same time and designating batteries in a more predictable usage and efficient use of them. It’s not perfect but is very good. The batteries aren’t completely independent in the compartments but don’t seem to leak power. Sometimes, when placing two batteries in, the second battery can falsely make the level of the first battery go up a notch, (25%), which might mean the energy transfer between them is from an original voltage differential of less than around 0.6V.

You can't fault these they have 80 plus hrs battery life, wireless charging, fast charge via USB C port, amazing sound and great bass and they are very comfortable for an on ear headphone.

I have to run GPS in my car at least 8-9 hours a day but it never goes under 80% of charge.very good product.thanks BH for carry quality product.
