Review on 🔋 Durable Travel Case for RAV Power 26800/20100/20000mAh, Anker Power Core 26800mAh/PowerCore +26800mAh, Dulla M50000 Power Bank 12000mAh, ROMOSS 30000mAh, Miady 10000/15000mAh by SKYNEW - Large Black by Jeffrey Nunes

I bought this as a case for my 20000mah Aukey which is only 8 inches long. Choose between medium and large. I finally went with the medium because I didn't want my case to be too long and I felt the 9.XX (medium) could give me enough room for a 7.XX in the power bank. My external battery just fits into the case, there is no more space (see photo). The other side of the case holds the external hard drive well. The case is more than thick enough to fit more items in the middle.
