Review: Nice product, worth a few dollars more - This is a nice little USB charger. I bought it to go along with a 12V battery bank that did not have a charging port. I mounted it in a small plastic container for ear plugs with an input plug from the battery bank. The efficiency of this charger meant that the 12V, 3000mah capacity of the battery bank will deliver a measured 5V, 5700 mah at the output of this charger - two full charges for my phone. I use the 12V battery bank for other purposes as well, but this is a nice added capability. If you haven't bought the battery bank yet, you can find some that already have this USB charger built in. However, if you also use the battery bank for low-noise applications, you might want to have a removable charger like this to eliminate the switching noise from the battery output when you are not using it. Nice product, worth a few dollars more. ADDITION: I noticed that the cable between this charger and my phone affected the charging current. My Samsung Galaxy 4 would only charge with 420 ma with a long cord, but would charge at 1.5 amp + with a short stub cable. This is because the phone detects the voltage drop in the cable and limits charging current. If you want to use the fast charge capability of this charger, make sure you use your shortest, heaviest cable between the charger and phone.
Review: Looks Promising! - I haven't had a chance to apply this board to my project yet, but I noticed some interesting things about it right out of the box that I thought were worth sharing. Though it can be seen in the pictures if you look carefully, the description does not mention the power indicator LED. I thought this was a neat feature. Another thing that isn't stated in the description is that the board draws ~5 mA without anything plugged into the USB port. Beyond those observations, I just tested that it output 5v, which it did.

## Features

- USB female interface output, widely used and more convenient.
- Rated Input: DC 6V-24; Rated Output: 5V 3A 15W
- With output short circuit protection, automatically return to normal output after short circuit faults removed.

### ⭐⭐⭐⭐⭐ quite handy
*by M***. on July 11, 2019*

Great way to make a backup USB power source out of a spare large capacity battery. Used it on a spare 12-18vAhr battery to be able to charge my phone many many times.
