MPPT 40A 12V/24V LCD Display Solar Controller Automatic Identification Off-Grid System Controller1. Adopt DC DC conversion technology and MCU technology. It can intelligently adjust the working point of the solar panel array, so that the solar panel array achieves the maximum power output. When external conditions change, the MPPT controller tracks the maximum operating point of solar panels based on MCU theory, so as to improve the efficiency of solar panels and reduce the cost of solar power generation. Compared with ordinary solar charge
1. Adopt DC/DC conversion technology and MCU technology. It can intelligently adjust the working point of the solar panel array, so that the solar panel array achieves the maximum power output. When external conditions change, the MPPT controller tracks the maximum operating point of solar panels based on MCU theory, so as to improve the efficiency of solar panels and reduce the cost of solar power generation. Compared with ordinary solar charge controllers, MPPT can increase the output efficiency of solar panels by 5% to 30% (the rate of increase in output is affected by the attributes of solar panels, ambient temperature and lighting conditions).

This is such a super cute and classy clutch. The fabric feels so good. I love the gold chain strap. It’s got a good about of room inside as well. Perfect for a dressy outfit and event.

Very good quality item.
Color: Small-brown
OMGOSH! I love this purse! It is exactly what I've been searching for. I don't normally carry a purse. Wearing jeans or pants most of the time, I use my pockets: phone, flat wallet, lipstick, keys, and I'm ready to go. Occasionally, however, I wear an outfit where the phone is too bulky, like in a dress pocket, or there are no pockets at all. Not sure how I came to own such clothing, but be that as it may, I've been looking for a purse that would be simple, functional, and cute. I don't like large purses and phone size purses are just too small that even my few items overstuff them. Then I end up clipping the keys on the side which is not very sophisticated looking (more hobo than boho) So the search has been ongoing, until my package arrived today! Yay!
This little Iswee purse is PERFECT! It has a clean design with just a few simple elements that give it that polished look. I got the small (6" high & 9" wide) in brown leather. The color is that warm, orangy-brown that I love. The leather is soft but sturdy not supple like a slouch bag but not stiff like a clutch. It is fully lined with interior and exterior, zippered and slide-in pockets. The hardware is a gunmetal color and heavy, seemingly of good quality. The over the shoulder strap can be adjusted with the buckle from 40" to 47" (length includes hardware) and is of a stiffer, belt like leather.
(It even smells like leather)
I may just order another in a fun color. It's worth every penny.

Small but holds alot
Color: Large Coffee
Love this bag! Dis a bit of research as I wanted a zipped bag, with outside pockets for my phone and not those inner pockets for holding credit cards. This is perfect for me. Very nicely put together and is a perfect color of brown. I will be using this alot.
