FNIRSI FNB48P USB Voltage Current Tester with Bluetooth: Fast Charge Detection

USB Voltage Current Tester with Bluetooth — Battery Testers, FNIRSI

Ever found yourself guessing if your USB charger is actually giving your gadget the juice it needs? Enter the FNIRSI FNB48P USB Voltage Current Tester—your new best friend for keeping tabs on USB power sources. Not only does it boast Bluetooth for those 'I’d rather not hover' moments (because let’s be honest, who does?), but it also keeps you in the loop with real-time voltage and current updates. It’s like having a backstage pass to your device’s power concert. And hey, it’s no slouch when it comes to fast charge protocols either, flexing its muscles across a 4V to 24V range and handling up to 6.5A like a champ. With four function curves for the data nerds and five ports to test multiple gadgets at once (because why stop at one?), this tester is a no-brainer for both pros and tinkerers. Bottom line? It makes sure your devices aren’t just surviving—they’re thriving.
