The Iniu 10,000mAh 20W Power Bank is currently available for less than $10 on Amazon, featuring a steep 49% discount applied via an automatic coupon at checkout. This deal significantly reduces the price of a portable charging solution from a popular Amazon brand, which has not recently seen its power banks priced below $10.
The power bank boasts a 10,000mAh (37Wh) battery capacity. When accounting for an approximate 80% power efficiency, it can fully recharge a Nintendo Switch (16Whr) about 1.9 times. For the upcoming Nintendo Switch 2, with its estimated 20Whr battery, the Iniu power bank can provide approximately 1.5 full recharges. This level of capacity means the Iniu power bank can more than double the total playtime for the Nintendo Switch 2, which has a battery life typically ranging from 2 to 6.5 hours in handheld mode.
For other popular devices, the power bank offers about 0.74 recharges for the Steam Deck (40Whr) and around 2.1 recharges for the Apple iPhone 17 (14Whr). Even the larger iPhone 17 Pro Max (20Whr) can be recharged approximately 1.5 times.
The 20W Power Delivery specification ensures that users can continue playing on devices like the Switch 2 even while they are charging, without experiencing battery depletion. This offer is time-sensitive, as such coupons typically expire within a few hours.
