Questions about RAVPower Rp-Pb043

Theoretically yes, but certainly only in hand luggage. Ultimately, however, it is the airline that decides.

Maybe the Pi is drawing more current than you are charging into the Powerbank.

Agreed - I was just thinking the same thing this morning when I plugged my phone in for the fifth consecutive charge. Super product !

RAVPower is too weak to charge the battery of a Surface Book 2. The output is 9~12 V 1.5 A max. The power supply of the Surface Book 2 has an output of 15V 6A. That is much more. A suitable cable might exist (google for "surface book to usb charge"). In principle, you could charge the Surface Book via the USB-C port. Microsoft warns against this, though: Yes, you can normally charge your Surface via the USB-C port. However, we strongly recommend using the charger that came with your Surface, as charging speeds with a USB-C cable can be very slow (depending on which power adapter and cable you use). Either way, RAVPower has far too little "juice"

I had exactly the same problem. After 20 hours of continuous charging, there was still no more juice. In the meantime, I bought a powerbank of another brand, which has rarely been used for 3 years but runs perfectly.

I think the charging of the computer is OK, if the cable is compatible. It will probably only allow one charge, and may be partial depending on the battery capacity of the computer. On iPhone I do almost 3 charges. For air transport, you have to take it in the cabin like any battery (never in the hold). I have already taken several times, it is necessary to check the maximum capacities which change according to the companies, but in principle 20AH = 100Wh in 5V, it is OK. I recommend to buy a "fireproof anti-explosion" bag, that reassures everyone. And if you feel that it heats up excessively (battery, phone, computer...) immediately warn the cabin crew who know what to do (fireproof containers, plunge in ice to cool down at all costs...).

No, that is not possible. It would have to support PD3 (Power Delivery 3.0, 45W), there are also other PowerBanks from RAVPower and co.

This product was delivered to me by mistake and I sent it back. I did a search for you though and I read that this seems to be the case. https://www.ravpower.fr/ravpower-rp-pb043-20100mah-batterie-externe-secours-charge-rapide-qc3.0.html But I can't be definitive. You should contact RAVPower directly.

It is compatible with first generation (2015) 12" MacBook. I've not tried it with the MacBook Air.

Just keep loading.

74.37Wh (Laut dem offiziellen Material Safety Data Sheet: https://www.ravpower.com/p/ravpower-20100mah-usb-c-power-delivery-power-bank.html )

Yes, it works perfectly. Even when it is recording.

The one I received included a Micro-USB to USB-C adaptor. It's really small, so you may want to check you package content. If you cannot find it, Digitec's support will probably help you get one. Keep us updated.

Hello. I have not tested this case (2 devices not compatible) but I know that the Quick Charge process will not be triggered if the connected device is not compatible and charge in standard mode only. And I have never noticed any overheating in this case.

Unfortunately, I do not know the technical data of your charger. Ideally, a Quick Charge 3.0 capable charging adapter is recommended. For example: Aukey PA-T9 (3A, 18W, Quick Charge 3.0) or Aukey PA-T16 Quick Charge 3.0 36W (3A, Quick Charge 3.0)

Depends on the laptop... You probably want a powerbank that supports PowerDelivery though.

I think Yes! I don't know exactly what this pass-through charging means. I couldn't find that out quickly. But if the battery is stressed (which it shouldn't be), it would be harmful to the cells to charge and discharge them at the same time! Above all, the charging time would increase if you were to do this! If I were charging a PowerBank and still had to charge something --> I would use a different socket, or find out exactly what pass-through charging means!

I have just tried it out, and it works perfectly at least with the two "normal" USB ports ;) (whether both ports then still charge at full power is something I can't judge at the moment).

I don't know what your Razer Blade Stealth consumes in operation, but charging is probably rather scarce, the Type-C output is only 15W (5V, 3A max). The maximum the powerbank can deliver is 18W (12V, 1.5A; 9V, 2A) from the Quick Charge 3.0 output, but then your device must also support Quick Charge 3.0.

Because Quick Charge ≠ Quick Charge. Qualcomm Quick Charge (3.0), which is considered a quasi-standard for Android, is in principle only supported by devices that have a corresponding Qualcomm processor (Snapdragon 835, for example). Many Huawei devices, on the other hand, use a Kirin chipset that only supports Huawei's own fast-charging standard.

In theory, without losses, approx. 7.5 times. Realistically, approx. 5 charges should be possible.

All connections are input & output capable, except 1x USB-A (iSmart).

It takes that long for me too. It's just that 20000 mah takes a while to get enough juice through. A new iPhone with approx. 2500mah also needs around 2 hours for a full charge, so it's not surprising that it takes several hours (sometimes 8 or more for me) to fully charge the powerbank.

Current is 3A so it should be 5VDC.
