How Does the PUJIMAX Charger Optimize Battery Charging Speed?
The charger uses adaptive current control to adjust charging rates based on battery capacity and type. For Li-ion batteries, it delivers 1A per slot, reducing charging time by 40% compared to standard chargers. Ni-MH batteries receive pulsed charging to prevent memory effect, ensuring optimal charge absorption without overheating.
This optimization is achieved through real-time impedance tracking that measures battery resistance 20 times per second. The charger’s microprocessor calculates ideal current flow using Peukert’s equation modified for modern battery chemistries. When charging two batteries simultaneously, power distribution dynamically shifts between slots based on individual needs – a drained 18650 cell might receive 800mA while a half-charged 14500 gets 400mA. This intelligent allocation prevents energy waste and reduces total charging time by an average of 18% in mixed-load scenarios.

Which Battery Types Are Compatible?
Officially supports 7.4V-9V Li-ion (10440 to 18650), 8.4V-9.6V Ni-MH (small packs to 3000mAh), and 9V Ni-Cd batteries. The charging algorithm automatically detects chemistry through terminal voltage analysis, with manual override via mode button for mixed chemistry charging sessions.
How Do LED Indicators Enhance User Experience?
Four-color matrix: red (charging), green (complete), flashing yellow (error), and blue (standby). The center ring displays charge percentage in 25% increments through segmented illumination. Error codes flash in binary patterns – three flashes indicates poor contact, seven signals incompatible battery type.
Can It Charge Non-Rechargeable Batteries?
Absolutely not. The charger employs reverse-polarity detection and chemistry verification. Attempting to charge alkaline or zinc-carbon batteries triggers immediate shutdown with error light sequence. Internal relays physically disconnect the circuit within 0.8 seconds of detecting primary battery insertion.
What Makes the USB Interface Special?
Features USB-C PD 3.1 compatibility, accepting 5-20V input. Includes built-in buck-boost converter maintaining 10W output even with fluctuating power sources. The cable incorporates ferrite beads for EMI reduction and supports data transfer for firmware updates through hidden service port.
“This charger represents a paradigm shift in consumer battery management. The combination of switched-mode power supply topology with coulomb counting creates unprecedented charging precision. Our lab tests showed 99.2% charge efficiency across 500 cycles – exceptional for its price bracket.”
