Galaxy Magnetic Wireless Battery Pack vs Techsmarter 20000mAh Portable Phone Charger Power Bank: which is safer?

Where these two actually differ

• We flag Lithium-ion thermal runaway (overcharge/physical damage) and Internal electrolyte irritation (puncture hazard) on the Samsung and not on the Samsung.
• We flag Lithium-ion thermal runaway and fire risk and Battery leakage or electrolyte exposure if damaged on the Samsung and not on the Samsung.
• The Samsung is Lithium-ion battery, aluminum, stainless steel body where the Samsung is Lithium-ion battery, plastic housing, circuit board components, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
