Overview
While the Giga Pump 2.0 may seem like a luxury item to some, it will save you plenty of time and effort when it comes to camp chores. Well worth the extra 3 ounces in my opinion. Instead of filling and refilling a pump sack over and over to inflate your sleeping pad, just hook up the Giga Pump, sit back, and let it do the work for you. It comes with 5 attachments: 4 nozzles for inflating and 1 for deflating/vacuum sealing. A drawstring carrying bag is included too. As if taking some of the work out of setting up camp wasn't enough, it can also serve as a lantern with three light settings. On the top of the pump is a small detachable handle that can be hooked to the gear loft loops integrated into most tents. Over all, the Giga Pump 2.0 is a great investment for backpackers interested in adding a helpful gadget to their camp chore routine without adding a hefty weight penalty.
Pros
Lightweight and compact. Depending on your gear, it can easily fit in the stuff sack with a sleeping bag or pad.
Built in light has three modes: low - 40 lumens, medium - 160 lumens, and high - 400 lumens. I rarely use the high setting. Low offers plenty of light while getting tucked into the tent at night.
Handle at the top easily attaches to gear loft loops. No need to fumble around the tent while awkwardly holding your headlamp.
Long battery life. I typically use this on three day trips, and it lasts the whole trip without needing a recharge. According to the product description, you can get about 10 hours of light on the lowest setting.
Cons
Nozzle attachments can detach from the port while in use. It helps to position the pump on its side between the baffles of the sleeping pad.
Inflation ports on sleeping pads vary by brand. So, finding a nozzle with a perfect fit may be a problem. Thankfully the silicon suction cup nozzle is very versatile. I've found it to be the best one when inflating my Nemo Tensor.
I purchased one of these a few months ago and while I haven't taken it backpacking, I did use it for a week straight camping in the Outer Banks. It did a nice job inflating and deflating 3 different pads on multiple days and never ran out of battery. Agree that it's worth it.
