Limit Macbook Charge To 80

I have the Delta 2 Max and 2 extra batteries. I really like the options in the app from being able to limit charge rate and AC always on, and much more. One extra battery fits nicely on top of the Delta 2 Max, but the Dela 2 Max does not fit snug on an extra battery, I wish it did. Overall I recommend. It does not take the place of a true UPS, but I already had a UPS anyway. My only complaint so far is one of the extra batteries came with a bad display, but I guess I'll keep it. I don't want the hassle of a return and I use the app anyway.

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

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.

Great adaptor for old MagSafe chargers to new MacBook Pro charge port.

Excellent~~Have yet to hit any buffer limit at 7fpm~~
