Most Tecno Androids come with free power bank and back flip cover if you buy them from an authorized Vendor/Tecno Partner or the Tecno office itself. Apart from the Tecno cover/case/pouch, my Tecno M7 also came with a free screen protector when I bought it recently at DealDey.
Apart from that, earphone, an original Tecno black battery, an original Tecno USB charger, SD card were also present in my M7’s box. I don’t know if tecno will keep shipping those free Tecno accessories with the latest Tecno phones but you can always ask wherever you want to buy your Tecno.
Did your Tecno phone come with a power bank and cover? Pls, let me hear from you.
