Today's Amazon deals of the day are great little pieces of tech for everyone

Are you in the need of a new SD card? A thumb drive? Tired of your cell phone battery dying when you aren’t near a charger? Well, Amazon has you covered today.

Amazon is running a one day sale on accessories from PNY. You can pick up a 32GB microSD card for $19.99, or a 128GB flash drive for $53.99. What really caught my eye, however, were the portable battery chargers. All of them come in metal cases, and two of them feature two USB ports for charging two devices at once while on the go. You can pick up the PNY P-B-7800-S01-RB portable smartphone charger for $28.49 today, 64 percent off its suggested retail price.

With all the gadgets coming out over the next few weeks, and the holiday gift giving season almost upon us, now seems like a good time to stock up.
