Compatibility:

Cell type: Designed for Li-ion 3.6–3.7 V cylindrical cells in the 18650 format.
Length fit: Spring rail supports ~30–70 mm; many protected 18650s are ~68–70 mm—check your cell length.
Chemistry: Li-ion only. Not suitable for NiMH/NiCd/Lead-acid/LiFePO₄ unless explicitly marked compatible (this model is not).
Input power: Standard USB 5 V sources (PC, wall adapter, power bank). Use reliable adapters/cables delivering ≥1 A.
Protected vs unprotected: Fits many protected cells; extra-long button-tops may be tight—confirm length before purchase.
Regional note (NZ): For mains adapters, use NZ/AU plug USB supplies from reputable brands.

Safety practice: Charge on a non-flammable surface; discontinue use if the cell becomes hot, swollen, or damaged. See Li-ion CC/CV charging principles for best practice.
