These Bestselling Portable Chargers Are Editor-Approved — and on Sale For Prime Day

iWalk Small Portable Charger for iPhone ($20, originally $35)

"I can't leave my apartment without my iWalk portable charger in my bag; in fact, I'd rather forgo headphones than this power bank. I love how small and efficient this charger is. I can fit it into my smaller bags, like a wallet on a chain or an evening clutch. Plus, this charger has a lightning port built into it, so I don't even need to bother with charging cables, which take up so much space. Although bigger power banks hold more charging capacity, the iWalk is much less of a nuisance to use; they're too big and clunky, and most of the time, won't fit into my nicer going-out bags. I've had portable chargers that can wirelessly charge my phone, but honestly, it's never consistent since my phone barely stays aligned with the charging pad while out and about. This model has three LED lights to indicate how much power is left in the portable charger.

The iWalk portable charger lets me simultaneously use my phone while it is fueling it up without taking up much space in my handbag, which I can't say for other options in the market. I appreciate this feature the most because I rely on Google Maps to get me around the city, and GPS takes up a good amount of battery. With this sleek and slim portable charger, I can extend my phone's battery life for at least a few more hours. I use the iWalk portable charger often, especially when I'm on the go, whether I'm busy running around in the city or when I'm traveling." — Anvita Reddy, assistant editor, Commerce

iWalk Portable Charger 4800mAh Power Bank ($40)

"When enough of my colleagues rave about a product, I'll typically end up purchasing it for myself just to see what all of the hype is about. Such is the case with this iWalk Portable iPhone Charger , which I had seen featured across my social media feed nonstop over the last few months — and now I know why. This isn't your typical clunky, tricky-to-use iPhone charger that takes forever to charge or, even worse, takes up a ton of space in your bag. Within the span of only an hour, the portable battery can be fully charged and ready to use as needed. With this tool, I can forgo a charging cord altogether as the product can be inserted straight into my iPhone's lightning port, which is fantastic because it's one less thing for me to have to worry about carrying around or transporting when I'm on the go.

I love the easy functionality of the product and the fact it's compact (and stylish!), so it doesn't feel like a nuisance to have to travel with it. I recently relied on my iWalk charger while attending back-to-back shows at NYFW, and it proved to be a lifesaver for those longer days outside of my hotel when my battery life would be drained from taking photos, notes, or just responding to emails." — Kyley Warren, assistant editor, Commerce
