Received the official hard case for the Anker Powercore 2000 last week and have been using it daily. Its a great case for keeping your battery and cables organized when traveling or when you just want to keep them together in your work bag. Im currently using it with my Powercore Speed 2000 PD and fits the battery perfectly. One side of the case has a elastic band that keeps the battery snug and secured and the other side of the case has a mesh pocket to store small accessories like cables. The textured exterior of the case feels strong and durable There's also a loop strap attached to the case allowing you to attach it to a carabiner or hook. Exterior dimensions measure about 8 inches long, 3 inches wide, and 1 1/2 inches tall. Case is securely closed by a zipper that goes all the way around. Overall, I can see this case lasting me a long time. A definite for anyone that likes to travel with their portable battery and cables often.
