My phone always dies on long days out and about, but I’m not a fan of carrying heavy power banks or having cords twist in my bag. The Anker Nano portable charger<\/a> is the only option I’ve found that I’ll actually use, and I’m excited to report (though with a bit of jealousy) that it’s currently on sale for just $12. The charger is typically $26, but a 31 percent discount and a $6 coupon bring the white and black models<\/a> to a record-low price.<\/p>\n Anker<\/p>\n<\/div>\n<\/div>\n<\/div>\n I personally vouch for Anker’s Nano portable charger thanks to features like its lightweight, small build, and, like I mentioned above, its built-in lightning plug. You can juice it up through its USB-C port, with the device typically holding one and a half charges for my iPhone 12 Pro (Anker also makes a model for Android<\/a>, which is our favorite portable option for a partial charge<\/a>). Plus, the device has four clear dots on its front to indicate how much charge is left.<\/p>\n There are a few downsides to Anker’s Nano portable charger, but none that are too much of a hindrance. You need to be careful if using inside a bag as the lightning charger<\/a> can sometimes move out of the upright position it needs to work. It also isn’t great if you’re looking to boost multiple batteries at a time or use it for days on end, as it does seem to die before I can get two charges out of it. Overall, though, its convenience is amazing when I know I’ll be out all day or traveling<\/a>.<\/p>\n Follow <\/em>@EngadgetDeals<\/em><\/a> on Twitter and <\/em>subscribe to the Engadget Deals newsletter<\/em><\/a> for the latest tech deals and buying advice.<\/em><\/p>\n<\/div>\n![](\"https:\/\/s.yimg.com\/uu\/api\/res\/1.2\/ZKcuICRMKhkQwjQM8RASjA--~B\/Zmk9c3RyaW07aD03MjA7dz0xMjgwO2FwcGlkPXl0YWNoeW9u\/https:\/\/media-mbst-pub-ue1.s3.amazonaws.com\/creatr-uploaded-images\/2024-05\/f53497a0-1db7-11ef-b9d6-058aa1a52fbe\")
