There’s nothing worse than picking up your mobile device and discovering that it’s about to die and you don’t have your charger with you. Instead of trying to remember to take a charger with you everywhere you go, the affordability of a 9v micro USB charger makes it easy to grab one for home, the office, the car and one to just throw in your bag so you always have one available.

Before you just run out and pick up the first charger you see, you really should take the time to make sure you are buying one that will actually offer a great charge, without taking all day to do it. The Samsung Adaptive Fast Charging USB Wall Charger comes with the wall charger and a removable charge and sync cable. This charger can take your battery from a 0% charge to 50% in around 30 minutes, and allows you to transfer data any time you need to do so.

If you spend a lot of time driving around, you’ll also want to have a good charger in your vehicle. The Maxboost 30W Dual Output Quick Charge 2.0 Car Charger for the Samsung Galaxy, Note and Nexus lines, as well as the iPhone 6S and 6S Plus offers up to 75% faster charging speeds than other car chargers. It includes both a Quick Charge Output and an additional USB port so you can charge multiple devices at the same time, and has Qualcomm certification for peace of mind that it will work with your device.

For those who want to make sure power is always available, the ReVIVE PowerUp All-in-One Charger offers two USB ports, a cigarette lighter plug, a wall plug and space for 9V or AA batteries so you can keep your device charged, even if an outlet isn’t available.

Keeping a 9V micro USB charger on hand will make sure you always have the power you need for your devices.
