ZapProof –
Plugged into WRONG charger (12V car adapter). Sparks flew – but it shut itself off! No damage. Over-voltage protection is witchcraft. Worth every penny for us electrically challenged folks.

Ran a mini-fridge + phone charger for 48hrs straight! Over-discharge protection kicked in at 5% instead of dying. Only gripe? Takes 4hrs to recharge. Still – campsite MVP!

Left this charging for 3 DAYS in my hot garage – didn’t puff or explode! Overheat protection saved my shed. Still holds full charge after 6 months. My old battery would’ve been fireworks by now.
