What to Look for & What to Avoid
Features To Look Out For
First, lets look at features that are important with a peanut lighter. The first feature to look for is a flat end. Some people like to use this lighter as a candle. To do that, you need a flat end on the lower half. Peanut lighters with a round end won't stand on their own.
A second feature to keep an eye out for is construction. You are going to find 4 kinds of material.
1) Aluminum: which scratches easily.
2) Stainless steel: which is durable
3) Titanium: very durable
4) Matte finish steel plated copper: Which looks great, but isn’t very durable.
Here's a third thing to look for. Is the insert removable? If so, then your little lighter can serve another purpose. You can store things in it. Just remove the lighter insert and put your items inside the lower half.
What Issues Exist With Peanut Lighters?
OK, so far everything sounds great. But in reality, peanut lighters have some issues. Especially when you're thinking of dumping all your other fire starting gear and replacing it with this.
One of the biggest complaints of the peanut lighter is "fluid evaporation". The key issue is the o-ring. Because the o-rings aren't made right, the lighter fluid dries in about 3 months. One-way to boost o-ring performance is to add Teflon tape or even silicone sealant.
Another issue with this lighter is the wick. Here's what is happening. Sometimes the lighter won't light, even though its full of lighter fluid. Here's the reason why. There's a wire holding up the wick, but sometimes the hole for the wire is too small.
This prevents lighter fluid from soaking the wick even though the unit is full of fluid.
One last issue is how tight the unit fits. At times the lower half can come loose and drop off your key chain. Fixes might include Teflon tape or Loctite. The last thing you want is to reach over for your lighter in a dire situation only to find it... missing!
