When I was updating this page, then coupon price was 47.99 USD for 11.1V 8000mAh (in Banggood). Price history, coupons and price alert are available on this page. Let’s see what best price is ATM.
Latest coupon and price update (UTC):
Banggood (47.99 USD)
Banggood warehouse is located in China. As you can see I didn’t find any active coupon for this product right now… Isn’t it too expensive? Hmmm, price is higher than average (which is 26.93 USD right now), so better set price alert down below…
