phrunt Posted February 23 Author Share Posted February 23 My Momax cost me $36 NZD delivered, $22 USD. It's so cool being able to get such cheap batteries to run a detector, and I can use it for other stuff like my phone too. 2 Link to comment Share on other sites More sharing options...
Tony Posted February 23 Share Posted February 23 Just to summarise.......all Power Banks when delivering USB power (5V) will lose about 25% capacity straight away. "Efficiency Losses" will depend upon quality of manufacturer with the best losing only an additional few percentage in capacity. The worst performers can lose an additional 10% or more in capacity. Some manufacturers advertise these specifications and others don't. I think ultimately you get what you pay for and buying higher quality powerbanks is the way to go. They are definitely not created equal. Unfortunately, the Momex must have very significant efficiency losses based upon dropping from 20,000 mAh to 11600 mAh (the first 5000 mAh capacity loss is to be expected in this case).....but kudos to them for including the specs. 1 Link to comment Share on other sites More sharing options...
phrunt Posted February 23 Author Share Posted February 23 My Momax is 10,000 and drops to 6000 mAh. Regardless, it's lasting a day, and for a PI a day off a battery of that price is outstanding. 1 Link to comment Share on other sites More sharing options...

Very reasonable thing to do, there are so many dodgy batteries out there, that's why I think dealers that sell the Algoforce should also sell batteries, why not? they can upsell, make a few extra bucks and benefit the end users by giving them batteries that are tried, true and tested. 1 Link to comment Share on other sites More sharing options...

Nitecore make some really good quality great stuff, I should get one to give it a go. I like the individual battery power specifications and realistically the coils on the Algo are the heaviest part, so having a bigger battery under your arm cuff is a good thing. It has square edges too so would lock in place very well, you may have found the perfect complementary product that dealers of the Algo should stock along with some good quality 18650's. Certainly it is worth investigating and I'll do so. Link to comment Share on other sites More sharing options...
Tony Posted February 23 Share Posted February 23 It's officially discontinued but still available at a few places......somewhat expensive but reasonable. $50 Aussie. https://www.oztorches.com.au/nitecore-f4-power-bank-battery-charger.html No USB-C connectivity....maybe the next model? I think Micro-USB is the achilles heal especially as an outdoors unit ?? Link to comment Share on other sites More sharing options...
