When the grid drops, the phone still has to work
Keep your phone charged for alerts, maps, and family calls. The 26,800mAh / 99Wh Portable Solar Power Bank is a backup phone battery you fill at the wall, then use with USB-C, USB-A, or 10W wireless when the house is dark.
Yes — if you start with a full pack and treat it as emergency phone power, not whole-home backup. The Portable Solar Power Bank stores 26,800mAh / 99Wh. Recharge it through USB-C in about 4 to 5 hours while you still have wall power. During the outage, keep the phone on a PD USB-C cable for the listed charge counts, or use 10W / 7.5W / 5W wireless through a compatible case. Charge a second phone on USB-A — up to three devices at once. A short high-current charging cable and a lanyard are included. The built-in panel is 5.93 × 2.81 in at 300mA/h for daytime top-off. For more solar, add a panel or the Solar Power Bundle. For AC loads, add the 300W Portable Power Station Max.
With a PD fast charging cable through USB-C, the pack can charge an iPhone 16 up to 5 times, an iPhone 15 up to 5 times, a Galaxy S24 up to 3 times, or an iPad Mini up to 3 times. Those are single-device estimates. Actual results vary based on device, battery condition, usage, temperature, and charging method. Screen-on weather apps and hotspot use drain faster than those counts — this capacity is built for that mixed communications load.
USB-C in and out (12V/1.5A, 9V/2A, 5V/3A), two USB-A ports at the same voltages, and wireless at 10W / 7.5W / 5W for compatible iPhone, Galaxy, and Pixel phones. Wireless works through most compatible cases — remove metal attachments, rings, wallet cases, and cards for the best connection. Keep one cable on the nightstand phone and wireless for a spare.
At 1 lb 4.1 oz and 6.93 × 3.74 × 1.14 in, this blackout phone charger lives in a drawer or on the counter — not in a basement generator room. Fill it before hurricane season. Lithium polymer, 99Wh, certifications CE/FCC/RoHS/MSDS/UN38.3.
The integrated panel provides up to 300mA of supplemental charging in direct sunlight, which can extend remaining power for another round of alerts. Fully charge via USB-C first. Need more solar? Pair a 40W, 60W, or 100W Portable Solar Panel or the Solar Power Bundle.
Before the outage: USB-C recharge in about 4 to 5 hours using the included short high-current cable. Put the bank next to the phone you use for emergency alerts.
During the outage: plug the phone into USB-C with a PD cable when you need maps and messages. Dim the screen. Use wireless when you want a one-cable-free top-off. Share USB-A with a second household phone. The product page also mentions up to 8 days of power on a single recharge; that is not a measured household-outage phone-runtime test.
1. Fill the bank on grid power. USB-C input: 12V/1.5A, 9V/2A, 5V/3A. About 4 to 5 hours. Micro-USB input: 9V/2A, 5V/2.4A. A 65W wall charger is sold separately. Current ship timing for this product is on the product page.
2. Run communications from the bank. Same USB-C table for output. Dual USB-A for a second phone or USB radio. Wireless 10W / 7.5W / 5W. Up to three devices at once.
3. Stretch runtime in daylight. Built-in 300mA/h panel. Add a foldable panel or the Solar Power Bundle for more harvest. If you also need lamps or AC, add the 300W Portable Power Station Max (300W / 600W peak, 256Wh LiFePO4) and keep this bank on phones.

The product URL still uses “26w.” Port tables list the voltages above; this page does not add a 26W output rating.
For best results: Fully charge via USB-C before the storm. The integrated solar panel provides up to 300mA of supplemental charging in direct sunlight, helping extend available power for phones.
Need more solar or AC? Pair a 40W, 60W, or 100W Portable Solar Panel, or the Solar Power Bundle. For AC-powered devices, choose the 300W Portable Power Station Max.
Built for the outdoors: IP66-rated protection helps guard against rain, splashes, dust, and everyday conditions. It is not designed for submersion.
Wireless charging: Works through most compatible phone cases. For the best connection, remove metal attachments, magnetic rings, wallet cases, and cards before charging.
Device charging estimates: Phone and tablet charge estimates are based on the listed devices using a compatible PD fast-charging cable via USB-C. Actual results vary based on device, battery condition, usage, temperature, and charging method.

USB-C with a PD cable is how KEUTEK lists the phone charge counts. Wireless is 10W / 7.5W / 5W through most compatible cases — useful for a second phone or when you want to skip plugging in. Remove metal attachments and wallet cases for wireless.
Fill it via USB-C (about 4 to 5 hours) before storm season and after each use, while you still have wall power. Solar is supplemental in direct sunlight.
Yes. Charge up to three devices at once using USB-C, two USB-A ports, and/or wireless.
