Anker PowerPort Solar Review: off-the-grid touring

Anker’s PowerPort Solar is a charging system suited to more powerful electronic devices, like larger iPhones and tablets. We head off-the-grid to the Peruvian Andes, loaded with framebag full of gadgets…

When I head out on an extended bike tour, I generally make sure I have a front wheel built up with my dynamo hub – a SON 28 wired into the excellent Sinewave Revolution. After all, while external ‘cache’ batteries are perfect for long weekends away (I suggest one with at least 5000mAh capacity), the ability to independently charge the likes of your GPS, smartphone, Steripen, and other electronic wizardry can be very useful during longer tours.

But for my most recent trip to Peru, I didn’t have a chance to rebuild my front hub into a 27.5+ wheel, so opted to travel with a solar panel instead. In the past, I’ve used small and light models that have worked well when conditions have been optimal, as they often are where I’m based in New Mexico. But as devices have become every more power hungry – particularly the likes of the latest iPhones and tablets – smaller panels often end up lacing in the consistency department, especially if conditions are cloudy. Given that I was visiting the Peruvian Andes on the shoulder season, I was expecting mixed weather. I also knew that charging points in this part of the world can be few and far between… and even when you track one down in a local barebones hostel, wiring can be notoriously sketchy…

For this reason, I opted to bring along Anker’s PowerPort Solar. It isn’t the lightest or most rugged panel on the market, but it comes highly recommended from around-the-world fatbiker, Ben Page, whose panel saw action across the length of Asia, and is now continuing to do so across Africa. Available from at $60, its price is certainly hard to beat.

There are two models available. The slightly thicker and heavier (535g) 21W Anker PowerPort Solar, which I took with me, offers 2 USB outlets and promises up to 2.4 amp per port or 3 amps overall – in translation, this makes it especially well suited to quickly charging the likes of an iPhone alongside a GPS. The PowerPort Solar Lite (15W) features one less panel, a single USB outlet and a max of 2.1 amps; so it’s still perfectly capable at charging a smartphone or tablet. Both fold down to the same size, one that fits easily into my framebag. If weight is an issue for you, by way of comparison, a SON dynamo/Sinewave revolution will add around 250g to your setup, with very little packing space required.

In use, the PowerPort proved very impressive indeed, even in cloudy conditions. Charging time is eyebrow-raisingly fast – comparable to a 2.4 amp charger in an electrical outlet, when the sun is out. It proved amply powerful enough to charge my iPhone 5s directly in cloud cover, without the need for an external cache battery, as it often required for fussy Apple products. Over the course of the last month, I’ve also used it to charge a Black Diamond ReVolt headtorch and my Outdoor Tech Buckshot topped up… so I was never without those all-important podcasts!

Compared to some solar chargers, the PowerPort doesn’t include its own internal cache battery. I actually see this as a benefit rather than a hindrance: there’s less to go wrong electronically and when your external cache battery wears out, it’s easy to source an up to date replacement. The panel includes a sleeve to house the devices you’re charging. In practice, it could do with more velcro tabs to stop contents from sliding out. Still, the pouch is a handy way of keeping cables contained when the panel is folded away, so you’re not rummaging around for them elsewhere and can set the panel up quickly whenever you to for a lingering break.

In terms of build quality, I don’t think the PowerPort Solar can quite match the complete weather-sealed goodness that other more expensive models have, like heavier and more expensive models from Bushnell, Powermonkey, and Goal Zero. Although there are attachment point eyelets to jerry rig it to your bike and it’s certainly stoutly built, the side pouch could to a more secure job at carrying devices you’re charging on the move, as mentioned above. If this is your intention, it would be worth sewing in an extra velcro tab or two. Bear in mind too that given its unfolded size, you’ll need a fair bit of real estate to attach it to. On a similar note, it’s a shame the top corners don’t include reinforced grommets.

Thankfully, the panel charges so quickly that I don’t think strapping it to your bike is often necessary. Certainly, I was never left wanting. My usual MO was to leave it out at sunrise while I prepared breakfast and broke camp, and pack it away last just before I was ready to roll out. This time alone was was usually enough to charge my Wahoo Elemnt GPS, from around 50% to 95% and keep my iPhone alive (tips: keep in airplane mode, turn off apps not being used, drop down screen brightness, and store in your sleeping bag at night). If need be, I’d unroll the panel at lunchtime too, just to top up any other devices. As a result, I very rarely found myself hunting around for plugs as soon as I arrived in town… true off-the-grid touring!

Wrap Up

Anker’s PowerPort Solar is powerful enough that you don’t need to leave it on your bike all day. This is just as well, as it’s internal pocket could certainly benefit from extra velcro tabs and a couple more reinforced grommets if you’re riding rugged, dusty roads. In practice, I found leaving it out when the opportunity presented itself – at breakfast and again at lunch – kept my devices amply charged up for my needs, even in cloudy conditions. It quickly became part of my packing system; the first thing to come out and the last to go away.

The inclusion of two USB outlets proved really useful, given that I combine an iPhone and a rechargeable GPS for navigating – as well travelling with other USB-powered device, like a portable speaker for those all important road tunes and podcasts! If you’re a gram-saving bikepacker, the PowerPort Solar will likely feel heavier and bulkier than what you might expect, even if it’s actually on the light side, considering its generous wattage, when compared to its competition. If all you only want a panel for emergency use and occasionally topping up your phone in bright conditions, there are smaller, lighter, less powerful options around – though I’d argue that in many situations, a 5000mAh+ cache battery is probably a better alternative (Anker’s Astro E1 is my current favourite).

As it is, the PowerPort Solar works extremely well and is particularly well suited to more demanding charging tasks. If, like me, you’re tethered to various electronic devices and striking out on a long tour, then it’s likely to be weight and space well invested, for an extremely affordable price.

  • Got one this year in Poland for about 48 USD. Anker’s product keep proving their good quality.

  • Idle Prentice

    Wow, so it looks like solar is finally serious competition. Fantastic.

  • Thanks for the mention. Glad to read that the Buckshot is keeping you up to date on your podcasts.

  • Juan Cool Romance

    agree! its amazing

  • garudablend

    Really appreciate the good write up and links, but i pretty much can’t keep my mouth shut – I deeply hate outdoor speakers – just about the time you start to get your nature groove on, when you think it’s safe to relax, some asshole comes along who thinks everyone in gods earth needs to hear J.Giles Band’s misogynistic peaen to double standards ANOTHER fucking time. And hey, aren’t they a wonderful person for bringing the party to you? Because i know my one regret leaving the trailhead is that Iwill no longer be assaulted at all times by someone else’s idea of good music (not).
    I could go on about how people who chose to “share” their music while bicycling or hiking are predisposed to chosing shitty music, but i won’t, because Sartre was close, but hell is really other people’s music. Anyone else’s
    music, Billy Joel or Tchaikovsky, is NOT what I’m out there for.
    It’s sonic littering, the aural equivalent of the un-policed blossom of used toilet paper wafting its funky way across the trail, redolent of the same oblivious self-centeredness and blatant disregard for other trail users, quashing the tiny fraction of an illusion of a “wilderness” experience we’re all out there to enjoy in the first place.

  • Hey Cass,
    So… million dollar question – would you pick it over your SON (assuming it’s built up in your chosen wheelset)?!
    Heading off on a six month tour next year with my girlfriend. I’m defo taking a SON (and Igaro), she’s tempted by the solar panel. Keen to keep clutter and weight down, which leans her towards the dynamo, but obvs good to have diversity of generation! Any thoughts?

  • Cass Gilbert

    I think having the two is the best option. The Anker is great for charging multiple devices in the morning when you’re pulling down the tent, and/or at lunch when you’re stopping for a picnic. The SON keeps a cache battery charging when you’re on the road. I haven’t come across the Igaro system but it looks good.

  • Thanks. More pondering to do – reckon I’m gonna end up carrying the solar panel as well at this rate… 😉
    Really recommend the Igaro – highest output and most efficient of all the converters (as far as I know) perhaps alongside the Forumslader. Switched from a Plug III and the Igaro charges at noticeably lower speeds, and much faster. It was the difference between charging on dirt roads and not for me.
    If you check out his FB page, he’s got some cool lights in the works too…
