Question 1

Is it usable with Sound Devices 688 recorder Mixer?

Accepted Answer

I had a quick look at the 688 spec, it looks like quite a neat piece of kit🙂. From the tech spec it uses a locking 4-pin Hirose connector, pin-4 = (+), pin-1 = (-).  10-18VDC. In theory if you could find an adapter cable then you could use the battery pack 12v supply, but tbh with the quality of kit you are powering it would be better to go for a better make of battery pack. The talent cell is more of a budget solution and it’s 12v supply is really pretty poor. I’ve tested and reviewed it. You’d be better to go for a better make; if you are looking for run time then something like the Maxoak K2, but you’d still need to find an adaptor.

Question 2

Would this run my celestron nexstar 8se, starsence align and auto focuser.

Accepted Answer

I have one of these powering my 8SE and it works fine. Maximum time used about 4 hours and still plenty left. I've not used it with the two add-ons you mention but hardly imagine they will use much power. Don't try to use batteries if you value your sanity. A 12v power supply will also work fine (eg. https://www.amazon.co.uk/SVNONVE-Transformer-100-240V-Converter-Monitors/dp/B0BHW4KJVD/ref=sr_1_16?keywords=12v+power+supply&qid=1684447640&sr=8-16) but the trailing lead is a liability.
I'm aware that this question was asked 7 months ago but this answer might help others.
Ignore the answer about using 5v !!

Question 3

Will this power a shure blx24 mic receiver (12–15 v dc @ 235 ma)?

Accepted Answer

I have had this for over a year now and its worked perfect for powering my computerised telescope. I can get about 4 to 5 hours of power a night from it. I need to leave it on charge for about 1/2 day. I dont think it would have any problem powering your mic receiver. I am very pleased with it.

Question 4

is it suitable for a cpap machine

Accepted Answer

Dear Customer,Thanks for your information.This battery can be used for RESMED respirator CPAP. But you must buy a 24V converter  （conversion from 24V to 12V direct current）.  And can be used for Philips Respironics old machines of 50 series and M series.  But it can’t be used for Philips Respironics new machines of 60 series and dreamstation series, it requires a special signal on the power input to function, it will not work with a simple wire between it and the battery. You can use the official 12v car adapter (to generate the proper signal) and a cigarette lighter jack to go between the battery and the CPAP.However, due to this battery capacity is not very high, if you use for the CPAP, the battery may not work a long time for your CPAP, we recommend that you buy a higher capacity 12V battery.If you have any questions, please don
