I’ve never really used an external, portable battery for my devices in the past, preferring to simply by extra sets of the batteries my device use. Recently, however, I decided to give the Anker Astro E4 (who comes up with these product names?) 1400mah portable battery a shot both because of the good reviews it received and the low price of just under $30 on Amazon.
Overall, I’ve been extremely happy with it. It charges fairly quickly, maintains that charge so it is ready to go even after a couple weeks of not using it, and provides all the juice I need when my phone or iPad is running low and I’m not near anywhere I can plug in conveniently. It’s also small enough that I can use it while, for example, using my phone to read a novel.
