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

Product Information

The issue with this small solar panel is it’s not far off useless, it’s adds about 50% more volume / weight but you can’t be assured of sunshine and it takes days to make 50% recharged. No, you’d want either a 21W solar panel, which is actually very useful and I’d consider in a non-minimalist kit, and/or just plenty / large Powercore. My advice is to use the built-in at high altitude where the UV is stronger and the temperatures lower, or to not use the solar panel at all and keep the Powercore in shade so it lasts the longest time, to not use solar at all and carry more Powercore, or invest in a larger panel (21W is a good product) and keep Powercore in cooler shade. For me the main selling features are the ruggedness, waterproofing, build quality and big capacity. Now if I do go somewhere sunny (e.g. beach) getting even a 10% boost to its already nice capacity is a bonus.

I measured 1.8 Wh of energy added to the battery in two hours of winter noon direct sunlight. During June, it might charge twice as fast (but only with clear skies and no shade, and while always pointed in the optimal direction). Even under optimal summer conditions, it would take more than a week for an empty Anker PowerCore Solar 20000 to recharge fully. Chart comparing measured Anker PowerCore Solar 20000 recharge watts for an AC charger, measured December solar power, and expected June solar power. Higher numbers are better. Recommendations USB-C ports can supply more watts than USB-A for fast recharging, and many PBCs have both. Newer devices needing recharging usually have USB-C.

The biggest thing about the power bank is has two output ports. There is a USB-C PD port, which is the focus point of this Power bank. Another port is USB-A, which provides standard charging. The charging range of the USB-C PD port on this power bank is 30W. The luxury of charging with this power bank is that it has more than the regular charging speed for Power Delivery charging. Other power banks have an 18W PD charging rate while it has a charging rate of 30W.

Far better is to get a huge solar panel and just a regular 20000 - actually the 26800 with dual input is a good match, or to give up on solar and just carry more Powercore instead. Portability: Many people use their power banks on the go, so I considered the dimensions and weight of each power bank to determine how easy it is to transport your power bank around with you. The non-minimalist one you’d potentially keep in the car for when you flee in a more controlled way, not running out a building, there you’d have lot, and of course the car, so more water, more clothing. Some people put this larger one in a metal box in the garden so if they flee an earthquake they don’t re-enter the building but go around outside and collect items from their larger kit. The following tables describe PBCs that meet the previously-stated criteria. Manufacturer specifications (below) were used to compute energy density (Wh/kg). Product availability is shown as of December 2021. Supply-chain issues and rapid product obsolescence are the primary reasons affecting product availability.

The following graphs show the differences between the manufacturer’s specified energy density (Wh), energy consumed during recharging, and energy delivered by the USB-C port for the Anker PowerCore 10000 PD Redux and Nitecore NB10000. Chart comparing Anker PowerCore 10000 PD Redux energy specified by the manufacturer, consumed during recharging, and delivered by the USB-C port, in watt-hours. Chart comparing Nitecore NB10000 specified, consumed, and delivered energy, in watt-hours. Table 8: Delivered Energy – Anker PowerCore Solar 20000 and Nitecore NB20000 name Pass-through charging is not supported, so you won't be able to charge the battery itself while other devices are charging. Performance and Conclusions Charge your PowerCore Speed 20000 PD with a regular wall charger. You might need a long time to charge it. So we recommend using a MacBook 29W adapter, MacBook Pro 61W, or 87W adapters. Anker also says that you can recharge the PowerCore 20000 in 4 hours with the provided charger. Conclusion Because Lithium dislikes heat less when empty, solar would be better at turning it from 0% to 20% so you’d get more success when it is empty. If not empty, if you used it each night and then left in sun, then you’d fair less well with the chemistry.

INIU 10000mAh Portable Charger t ech Specs: Charges 2 devices at once | 1 USB-C port | 2 USB-A ports | 78% charge within 1 hour The Anker PowerCore Solar 20000 includes a built-in flashlight: The Anker PowerCore Solar 20000 showing three white LEDs at one end.Well got my hands on the NB10000 Gen 2. The LEDs very easy to read now. I also like the yellow outline around both ports. Weight is the same. Mine came above spec at 155g. What has not improved and maybe has gotten worse is the accuracy of the LEDs. I drained the bank-made sure of it. Plugged it into my 20W Anker Nano(511) using USB-C to USB-C. Within 20 minutes the first LED was solid and the second was blinking. At 40 minutes in the second LED was solid and the third blinking. Finished charging at 3h 20minutes. I have a hard time believing it was at 66% capacity in 40min.
