SPERAS ALL4: Smart 4-Slot Battery Charger with LCD Display
Take the guesswork out of charging. The SPERAS ALL4 features an intuitive LCD screen for real-time monitoring, 4 independent channels, and smart auto-detection to safely charge mixed battery chemistries simultaneously.
SPERAS ALL4 Key Features
🔋 Independent 4-Slot Mixed Charging
Independently charge 1, 2, 3, or 4 pcs of AA/AAA rechargeable batteries at once. You can simultaneously mix 1.2V Ni-MH / Ni-CD cells with 1.5V Lithium-ion batteries without any compatibility issues.
📺 Visible Charging Process
The built-in LCD screen dynamically shows the real-time charging process. Each battery slot has its own status indicator, allowing the battery power level to be monitored easily at a glance.
🧠 1.2V & 1.5V Auto-Detection
The ALL4 microchip automatically identifies whether you inserted 1.2V Ni-MH/Ni-CD or 1.5V Li-ion batteries. It will switch off automatically after a full charge, ensuring 100% safety and preventing battery degradation.
⚡ DC 5V/2A Fast Charging
Equipped with a modern DC 5V 2A fast charging input port via USB-C. This significantly boosts power delivery, helping you save a lot of charging time compared to standard models.

Frequently Asked Questions About Smart Chargers
What are the advantages of a smart battery charger with an LCD screen?
Traditional chargers rely on a simple LED that often leaves you guessing. A smart charger like the SPERAS ALL4 with an LCD screen allows you to monitor the exact real-time charging progress of each individual cell. More importantly, its smart microchip prevents overcharging by automatically cutting off power when a battery is full, significantly extending the overall lifespan of your rechargeable batteries.
Can I charge 1.2V Ni-MH and 1.5V Lithium-ion batteries at the same time?
Most standard chargers cannot safely mix different battery chemistries. However, the SPERAS ALL4 features independent channels with advanced auto-detection. It instantly identifies whether you inserted a 1.2V Ni-MH/Ni-CD or a 1.5V Li-ion battery and applies the correct voltage. This allows you to mix and match different chemistries and sizes simultaneously with 100% safety.
Can you use a portable power bank to charge AA and AAA batteries?
Yes, but it requires a charger with a modern USB input. The SPERAS ALL4 is equipped with a DC 5V/2A USB-C fast charging port, making it highly versatile. Instead of relying on a wall outlet, you can plug it directly into a portable power bank, solar panel, car charger, or laptop, making it the perfect EDC charger for camping, travel, and emergency preparedness.
Do I have to charge batteries in pairs (even numbers)?
No. Unlike older, cheaper chargers that force you to charge batteries in pairs, the SPERAS ALL4 utilizes completely independent charging circuits for all 4 slots. You can confidently charge exactly 1, 2, 3, or 4 batteries at a time, in any combination of AA or AAA sizes.
Does the ALL4 charger automatically stop when batteries are full?
Absolutely. Once the dynamic battery icon on the LCD screen becomes completely solid, it indicates a 100% charge. The ALL4's intelligent microchip will immediately stop delivering current to that specific slot to prevent overheating and battery degradation, allowing you to leave them unattended safely.
