Anker PowerCore Solar 20000, 18W USB-C Power Bank 20,000 mAh with Dual Ports, Flashlight, IP65 Splash Proof and Dustproof for Outdoor Activities, Compatible with Smartphones and Other Devices

While this unit only has one USB port and a single USB-C charging connection, it's proven it's worth dozens of times over during the few months that I have owned it. I would have also liked a micro-USB connection and a second USB port, but I wonder how those would have impacted this battery pack's performance. (Sorry, I'm not an electrical engineer - would multiple ports generate too much heat? Incidentally, this item does feature a simple overheat indicator if your solar charging is too aggressive.) Whether you're plugged into an AC outlet to recharge or relying on the capable solar panel, it takes a while to get a full charge, but once achieved, that's where this Anker product really shines (literally & figuratively). The end has three LEDs which together feature high, low, or 3-flash signal settings, lighting up a campsite, roadside tire change, or indoor living space with a wide-area radiant glow. I can easily charge two Anker flashlights, an iPad/Kindle, a Bluetooth headset and a smartphone, with plenty of power left in reserve for more phone recharging and the ever-present solar panel always willing to contribute more. A couple of anchor points on the outer casing would be a welcome addition to allow for attachment to a pack or dashboard with more than a built-in lanyard. In the end, this is a solid investment in mobile power. It could benefit from a couple small improvements, but really the only drawback I foresee is weight - don't pack this for your ultralight backpacking adventure! If you're on the fence about this one, take a chance - Anker has made a great one and you'll find it worth the price! FWIW, save it to your shopping cart and wait for a sale price update, perhaps during Cyber Monday or Amazon Days. Got a great deal this way!

Ah yes, the nker PowerCore Solar 20000—a power bank that proudly flaunts its solar charging abilities like it’s the next big thing in portable energy. Spoiler alert: it’s solar-powered, so if you’ve got about a day to spare, and maybe a mild obsession with staring at the sun, this little guy’s for you. With a massive 20,000 mAh battery, it promises to keep your devices alive through multiple episodes of doom-scrolling or binge-watching cat videos. But here’s the kicker: if you want to juice it up with solar power, better pack a lawn chair, some snacks, and maybe a good book—because it takes a whole day of sunbathing to get a decent charge. Who knew charging a power bank could double as a sun therapy session? Dual USB ports mean you can charge two devices simultaneously—which is fantastic if you have two phones, or one phone and your burning patience. The 18W USB-C port is speedy once the battery is charged, but getting it there via solar? Let’s just say it’s a slow love story between the sun and your power bank. Bottom line: If you’re planning a desert island getaway or trying to perfect your patience skills, the nker PowerCore Solar 20000 is your dream companion. Otherwise, maybe just plug it in and skip the solar spa day. 5 stars for ambition, 3 stars for patience, and 1 star for convincing me I’m a part-time solar panel.

Power pack is a beast. In testing, charged my iPhone 4 times and my iPad pro once, still showed one dot of power. Took forever to charge to full capacity, actually stopped charging at three dots overnight. Unplug/replug and it finished. Same issue with phones, they get up to about 85% then the power bank stops charging them. Unplug/replug and it brings them up to 100%. Using an anklet usb to lightning cable. Usbc to usbc apple did fully charge iPad pro on the first try. Not sure if the incomplete charging is a safety feature but I need this rugged power bank for a week-long camping trip this summer, so hopefully it holds up until then. A bit pricey but Anker is a great brand and worth the extra $ for quality over the who knows where they are made companies (China). I’ll try the apple lightning cable next to see if it can charge the phones fully - maybe the anker cable is loose. Overall good, I have no expectation that the solar panel will do anything, I can’t even figure out how to know if the panel is charging the battery or not. Instructions are typed in 2 pt font.

Best battery charger I have , been five years I believe go camping and it’s gotten wet and sand in it and fallen hard and concrete but work perfectly

The PowerCore solar 20000 is a beast! It's huge and high in capacity. The first thing I noticed upon unboxing was the build quality. It is well built and solid in construction, it feels great when holding it in my hands. The unit came partially charged with 2 of the 4 blue battery indicator lights illuminated when I powered it up. It took approximately 6 hours to fully charge via my wall charger. After fully charging, it charged my old Samsung Note 8 via the USB type C port (Not solar) from 64% to 100% full charge in 37 minutes, the unit charges pretty fast through the onboard USB type C port. I have not tried charging through its available USB A port or solar yet. The LED flashlight a cool feature in itself. The lights are nice and bright but not blinding. The only drawback for me is the dust cover that protects charging ports from dust and debris is a little tough to open. If you are like me and you like keep your finger nails cut short, it is a little bit of a struggle to open the dust cover on this device. For those that have an older device like my Samsung Note 8 with USB type C charging port, I'm pretty sure this power bank will work for you. My phone was not on the compatibility list in the product description but, this unit charges my Note 8 just fine. Overall, I am super pleased with purchasing the PowerCore Solar 20000 and I look forward to using for backup emergency use or for hiking, camping fishing trips with the family. Another fantastic product made Anker.

Ottimo, sotto ogni punto di vista...forse leggermente pesante. Comunque consigliabile

La fabricación es sólida y la protección de goma es muy buena, además de que la capacidad de es muy buena. La placa solar funciona, pero hay que tener en cuenta que con ese tamaño es muy limitada: necesitas buen sol y muchas horas para cargar una parte, así que hay que tener en cuenta que no sirve para estar cargando continuamente otros dispositivos sino para mantenerlos en un funcionamiento mínimo (o agotarás la batería interna muy rápido y no dará tiempo a que se vaya recargando).

Schnelle Lieferung, wie immer bei Amazon. Einfach zu bedienen und lädt zuverlässig in der Sonne. Toll ist auch die Taschenlampe. Wirkt robust und Qualität ist top..

The PowerCore solar power has really grown on me and for each day it delivers good solid charging, I feel happier and happier with my purchase. At first I felt intimidated by its rather large size and weight. It’s 7in x 3in and over 1 inch thick and weighs over a pound. That’s much larger than any of the other powerbanks I own, but the high capacity, built-in flashlight and rugged casing were things I was looking for in a camping powerbank. The build quality is superb, the seams are flush and even throughout, the materials feel high quality, especially the back and rubber surround band. The unit feels solid and there’s absolutely no creaking even when applying torsion on opposite corners. It has two charging ports: a USB C which can deliver up to 18 W (9V at 2A, or 5V at 3A), and a USB A which can deliver up to 12 W (5V at 2.4A). They are protected by a thick rubber sealed door which should ensure that unit’s water resistant rating is met. The bank charges fast and consistently, and the capacity reported is absolutely real. I charged fully our 5000mA iPad 4 times, so the the math adds up to the reported capacity. I wish Anker had included one more USB C port, with passthrough, but I understand that’s more of feature of the PD chargers. The unit is controlled by a single button, which features multiple functions: long press for flashlight, double press for trickle charging, and single press to switch between flashlight modes when on. The built-in flashlight is quite bright and has 3 modes : high, low and flashing. The solar panel is a neat add-on as a top up, but I will probably need a much larger 18-20W solar panel in order to charge the power bank fully in a reasonably short time.

I couldn't get the unit to charge off the usb at first but was then helped by Anker who informed me you have to use one of their wall adapters in order for it to work. Excellent customer service on the part of Anker. 👍 Torch is brilliant and comes on on the lower setting first, which is good as this conserves the battery inside more, but with the next setting being full blast and then s.o.s. mode, I have no doubt that these would also come in handy if needed. Overall, the unit is very solidly built and you can feel the quality when you first pick it up. Even the plug covering the sockets stays in SO well. There hasn't been enough sun as yet to allow the solar panel to work, but it even tells you when it's getting too hot as well! I understand the solar panel is more used to maintain the charge while it charges another device as it would be very slow to recharge the unit if relied on, on it's own.
