What Makes a Good Stun Gun with Extra Battery Confidence

Here’s what I tell my own daughter when she’s shopping for a stun gun with extra battery reliability in mind:

• Look for a battery meter — it tells you the truth before you need the truth
• Rechargeable lithium batteries hold charge longer and don’t degrade like old NiCad
• USB charging means you can top it off anywhere — car, office, nightstand
• Test it monthly — a stun gun with extra battery life on paper still needs a habit behind it

Quick Questions

Does the Fang come with a second battery?
No — it doesn’t ship with a spare. What it does have is a battery meter, so you always know your charge status and can recharge before you’re caught empty-handed.

How long does the battery last on a single charge?
Like most rechargeable stun guns, it holds a charge for weeks of standby use. I still recommend checking that meter regularly — don’t let it become a surprise.

Is a battery meter really that important?
You bet. A stun gun with extra battery capacity does you no good if you don’t know when it’s low. The meter takes the guesswork out completely.
