Question about RAVPower Rp-Pb043

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...).

Good luck!
Same for me, as long as your tablet, computer allows a charge from a voltage of 5V, there is no problem...
For the plane, no problem either...
There were once problems with a Samsung phone (S7, I think) whose battery could explode but to my knowledge, this must be the only case that was banned on flights :-)

Hello, you can charge anything with this battery, computer, tablet, phone. I use the Samsung brand but I think it is also designed for iPhone. I can't answer your question about the plane but I don't see what the problem is.
