HOHMTECH SCHOOL 2A CHARGER has a 3-tier amp BLD (battery length detection) System; has a variable input voltage IPR (input power regulator) feature.

It is equipped with BLD System, which automates the step-up/down output so both small and larger cells charge at the proper rate (0.5A, 1A, 2A(single only) per channel with 2A total distribution).

HOHMTECH School 2A Charger Features:

• BLD System: Battery Length Detection automates charge amplification & reduction on li-ion cells.
• Low Voltage Activation: Allows overly discharged li-ion batteries down to 1.95V to be charged via a 200mA stimulate charge.
• Input-Power Autonomous Regulator integration (no more stressing USB power adapters or ports)
• Compatible with ALL li-ion cells from as short as 30mm to as long as 73mm
• LED indicator that reports [green/red] color and blink variation for quick/easy readout
• PCB/PCM compatible so even protected cells arent left out in the cold
• Protection: over charge; short-circuit; wrong battery type detection; reverse polarity
• Supports Li-ion Battery Size (included but not limited to): 10440, 14500, 14650, 16340, 16650, 17650, 17670, 18350, 18490, 18500, 18650, 20700, 21700, 22650, 26500, 26650

Includes:

• HOHMTECH School 2A Charger
• USB Cable (Wall Plug Required, with 2A output)

Disclaimer: Do not leave batteries unattended while charging as this may result in damages.

WARNING:

The user must have appropriate understanding of lithium ion batteries before purchase. Use caution when working with and using lithium ion batteries as they are very sensitive to charging characteristics and may explode, burn, or cause a fire if misused or mishandled. Always charge in or on a fire-proof surface. Never leave batteries charging unattended. Buyer is responsible for any damage or injury caused by misuse or mishandling lithium ion batteries and chargers. No express or implied guarantee of compatibility with any device can be made. Charge only with a smart charger designed for this specific type of lithium ion battery. Do not mix and match old and new, used and unused batteries.

• Misusing or mishandling lithium ion batteries can pose a SERIOUS RISK of personal injury, property damage, or death
• BATTERIES MAY EXPLODE, BURN, OR CAUSE A FIRE IF MISUSED OR MISHANDLED
• ONLY use with proper protection circuitry
• ONLY use within manufacturer specification
• DO NOT store loose in pocket, purse, etc. always use a protective case
• KEEP AWAY from metal objects to prevent short circuiting
• DO NOT short circuit
• DO NOT use if wrapper or insulator is damaged or torn
• DO NOT use if damaged in any way
• DO NOT overcharge or over-discharge
• DO NOT modify, disassemble, puncture, cut, crush, or incinerate
• DO NOT expose to liquids or high temperatures
• DO NOT solder
• User must be familiar with handling lithium ion batteries before purchase
• Usage of batteries is AT YOUR OWN RISK

Local regulations and laws pertaining to the recycling and disposal of lithium ion batteries vary so please consult your local jurisdiction regarding appropriate disposal.
