| Jan 8, 2023 at 20:47 | comment | added | Solar Mike | As for a powerbank, the best one I can use runs a 2000W inverter for 6 hours. | |
| Jan 8, 2023 at 20:46 | comment | added | Solar Mike | Ahh, so for those that have cheap / low power laptops but some of us need 85W power supplies as we need the power and capacity. | |
| Jan 8, 2023 at 20:44 | comment | added | 3244611user | Ah, is our misunderstanding stemming from that you assume the power-bank will be unusable for a laptop? My relatively small powerbank (5× 18650 cells) is also able to charge my laptop... Also as USB-PD allows constant re-negotiation of deliverable power, the same device could deliver 100W (20V@5A) or 60W (20V@3A) in AC mode and e.g. up to 45W (15V@3A) in battery-powered mode. 45W is still enough for most laptops. | |
| Jan 8, 2023 at 20:41 | comment | added | Solar Mike | Less components as I only need one power brick for 2 things whereas you suggest 1 built-in to the powerbank and a second for the laptop. | |
| Jan 8, 2023 at 20:39 | comment | added | 3244611user | Ah, I misread your reply slightly indeed. Sorry! But if I understand correctly this time, this only holds if you already have a sufficiently good power supply (which I think many people still do not, I just purchased a new one the other day) and/or for short trips (where you only carry either a PSU or power-bank). To the "charger for the laptop with a second charger built-in to the powerbank": yes, you need one AC to battery and one DC battery to USB-C PD converter. However, as I outlined in my original question, I think you need more components when you have a separate power-brick and -bank. | |
| Jan 8, 2023 at 20:05 | comment | added | Solar Mike | Ahh, but when you have a charger for the laptop that also works for the powerbank then your argument fails to fly... having to have a charger for the laptop with a second charger built-in to the powerbank is a waste as I outlined above. And I did not write my answer based on home/office. | |
| Jan 8, 2023 at 19:56 | comment | added | 3244611user | Thank you for the reply. I understand you arguments for stationary (home/office) use (where the mass and size do not actually matter that much). However, when traveling, many people now carry both a charger and a power-bank around. The two devices together should have more mass, volume, and cost than if you were to combine them in the same housing. | |
