mAh measures charge capacity; h measures elapsed time. With a specified usable charge and constant battery-side current, ideal duration is charge divided by current. A capacity label alone does not fix how long equipment runs.
PokerMagicShop operates the linked commercial catalog. This first-party explanation and original illustration were prepared with AI assistance. The arithmetic is hypothetical, not a product test.
Same charge, two different loads
Define two independent cases, each with 1,200mAh of usable charge. In each case, the current is constant and measured at the same battery boundary as that charge. These are assumptions, not nominal battery ratings or measured operating conditions.
Ideal time (h) = usable charge (mAh) ÷ constant current (mA)
Teaching case: A
Assumed usable charge: 1,200mAh
Assumed battery-side current: 100mA
Ideal calculation: 1,200 ÷ 100 = 12h
Teaching case: B
Assumed usable charge: 1,200mAh
Assumed battery-side current: 400mA
Ideal calculation: 1,200 ÷ 400 = 3h
Four times the current gives one quarter of the time within this defined model. It does not establish that a real cell retains the same usable capacity at different discharge currents.

Compare the actual catalog statements
Power wording in a poker analyzer comparison can describe different quantities. Keep the host and accessory statements attached to their own records.
The Phoenix Poker Analyzer Device labels its Battery Pack “3200mAh high-density polymer cell.” That is a product-level capacity statement.
Separately, the Accessories & Earpieces category labels Battery Performance “High-density micro-cells (4-6 hours continuous).” Its source is https://pokermagic.shop/en/categories/accessories. This category description supplies no Phoenix duration or guarantee for every accessory.
Neither statement supplies the other’s missing quantity. Do not combine them into a current estimate or use the fictional 12h and 3h to rank products.
Why real running time needs conditions
NIST’s unit table identifies ampere-hours as charge. Texas Instruments’ separate camera-design calculation, section 3.4.2, uses capacity alongside current and operating-time conditions. Its design values do not specify our catalog.
The teaching model excludes variable load, temperature, cutoff, ageing, self-discharge and conversion losses. It explains a quantity relationship; it predicts no product’s runtime.
