I have been using my Promate Powerbank for a while now, and while my other huge ones have already met their untimely end of life saga, this one is still fighting and has really huge juice which lasts me 3-4 days of power needed for my coverages. Just heard from the grapevine that the company is even extending their warranty for up to two years which is good for naysayers and wouldn't believe its quality. They are now also selling on their main website philippines.promate.net and in Lazada. So make sure you are getting the genuine one so you stay protected and safe.
They do worldwide shipping and does it free for orders 1000 and above, if you are planning to put some interesting things on your friends socks this Christmas,maybe a Promate would do eh? Aside from the powerbanks, they've got a ton of other gadgets and accessories in store. You now can shop for it right in the comforts of your own home. Splendid idea!
