    Its a cheap, quality battery that will do what you need. Doesnt hold much battery life and uses a micro-usb connection to charge (usb-c same as phone for easier charging is preferred). I use this with a small wire at the gym in my bag or pocket if my phone is low. Keeps it from dying no problem and is compact enough to not notice.
