Smart Auto-Disconnect Phone Charger — Stops at 100% to Protect Battery and Save Electricity

Charging your phone to 100% and leaving it plugged in overnight degrades your battery every single night.

Lithium-ion batteries degrade faster at high charge states. Keeping your phone at 100% overnight — which is what most Canadians do — causes measurable battery capacity loss over months. After one year of overnight charging, a battery that once lasted all day may now die by 3pm. The smart auto-disconnect charger solves this by cutting power automatically when your phone reaches the set charge level, then resuming when it drops below the minimum. Your battery stays in the optimal 20-80% range that maximizes long-term capacity.

Features

• ♦ Auto-disconnect at set charge level — cuts power at your configured percentage to prevent overcharging
• ♦ Auto-resume function — resumes charging when battery drops to set minimum level
• ♦ Works with all USB-charged devices — phones, tablets, earbuds, and other USB devices
• ♦ Digital display — shows current charge level and charging status
• ♦ Reduces electricity consumption — stops drawing power when charge is complete
• ♦ Compact plug design — works with your existing charging cable

Frequently Asked Questions

Does overcharging really damage phone batteries?

Yes. Battery engineers universally recommend keeping lithium-ion batteries between 20-80% for maximum long-term capacity. Sustained high charge states cause measurable electrochemical degradation. Most phone manufacturers now include software charge limiting for this reason — a hardware solution like this charger provides the same protection regardless of which phone you use.

How much battery life does it save long-term?

Studies show batteries maintained in the 20-80% range retain significantly more capacity after 500 charge cycles than batteries regularly charged to 100%. This translates to your phone lasting a full day after 2-3 years instead of dying by mid-afternoon.

Does it work with fast charging cables?

Yes. The device passes through the charging signal including fast charging protocols. The auto-disconnect activates at the set level regardless of charging speed.
