In the quest for the ultimate geek backpack, which you would need in case of the zombie apocalypse of course, we have come up with the list of the seven indispensable items that everyone, especially geeks, should have in their backpack.

1. The portable battery pack.

Whether it’s a specific one that fits your smartphone or one that has USB ports that accommodate any charging cable, a spare battery pack is one of the best things you can add to your bag. When you’re buying a spare battery pack the figure you’re going to be looking for is the mAh (milliamp hour) rating which is how much charge the battery pack can hold. An iPhone 5s for instance has a 1570 mAh battery while the Samsung Galaxy S4 is rated at 2600 mAh. Buying one with more USB ports is always preferable so that you can charge other devices at the same time. Our favourite battery pack at the moment is the 11 000 mAh one from Lenmar which can charge up to three devices simultaneously.

2. Portable Wi-Fi

Not having the internet is tantamount to geek suicide. So when building out your geek bag you’ll need a portable Wi-Fi hotspot and when it comes to mobile connections you’re going to want LTE. The Huawei E5776 mobile Wi-Fi hotspot is capable of up to 150 Mbit/s on LTE and 43.2Mb on DC-HSPA+so no matter what network you’re on you’ll get the fastest possible connection at all times. The 3000mAh battery pack should be enough to keep you going through at last the standard 8 hour work day but if it starts to run a little low, you can always juice up with your battery pack.

3. A Torch

Never underestimate the need for a decent torch because just when you do, there will be load shedding. When picking a torch for your bag we always go for a USB rechargeable torch so that you can always have some sort of light available even if you have to borrow some power from the battery pack you carry in your bag. The HexBright Flex torch was initially a Kickstarter campaign which made its target nearly ten times over. It’s an open source programmable torch that is USB rechargeable and outputs a phenomenal 500 lumens of light. Basically it’s the torch that you can put your geek credentials behind.

4. Tools

As a geek you may be required to strip down a notebook from time to time to upgrade the hard drive to an SSD or swap out the RAM. When it comes to stripping down tech no one is more adept at it than the folks from Ifixit and when it comes to toolkits their Pro Tech Toolkit is the one to take with you. With a 54 bit driver kit capable of tackling every screw known to man you’d have to agree with them that it “Will tear down all mainstream laptops, cellphones, and flux capacitors.”

5. Flash Drive

Flash Drives are the most ubiquitous form of storage available today and with good reason. Non-volatile flash memory is a fantastic way to transfer files between two machines. With the advent of USB 3.0 more and more computers have the ultra-fast connectivity option and you should have a flash drive that can take advantage of it for when you need to get a file quickly. SanDisk’s extreme USB 3.0 64GB flash drive boasts some of the fastest read/write speeds out there and 64GB of space isn’t anything to turn your nose up at.

6. Notebook Charger

A spare notebook charger is a must for your bag. If you forget to charge your notebook the night before a major all day out-of-office conference not even the latest generation of processors will get your machine through the day.

7. Earphones

A great pair of earphones is a must for any geek on the road. If you’re on a plane watching a movie or just need to listen to some of your own music while you work. Nokia has teamed up with Monster to create the Purity line of headphones and earphones and the ones we’re interested in is the in-ear stereo headset. The come in a neat carrying case to protect them and have flat cables to prevent them from becoming entangled. They sound fantastic too, just in case you were wondering.
