While the original HooToo tripmate does not have port covers the RavPower does. Interestingly the HooToo Titan does too. I'm not sure what the use-case is for the port covers because It's not like I'll be using submerged although at 10,000mAH or even 6000mAH it would not take much to generate heat or start a fire. The HooToo Titan is proportionally bigger than the Tripmate original.
The thing that bothers me most is that the firmware versions of all 3 devices are the same even though the HooToo Tripmate is distinctly different and the HooToo Titan is almost identical to the RavPower. Let me state, again, that the version numbers are the same, the user manuals are nearly identical, and the support phone numbers are the same.
PS: I did receive a response to my support request at HooToo. The person I communicated with is clearly not an English speaker and the information I received was clearly non-responsive.
