Having to have your charger connected to accept a job is more likely to be a function of the software rather than a battery issue.
We also have an option where no charger indicates an out of vehicle condition so depending on how the company works, you may or may not get a job.
GPS reliable?? That's a completely different issue that's not really related to the batteries or chargers.
Most devices these days give reasonable GPS performance although some of the cheaper devices can be a bit slow at acquiring the satellites.
Last week, we tested some Kasam devices that quite a few of our customers use.
They were ok but not quite as snappy as more up to date units and the GPS was a bit slow to kick in but for about £70 they were good.
We've never come across a charger that won't provide enough charge for any device that we use.
It's actually the phone that determines the charge rate not the charger and most phones are set to charge at about 0.7 amp.
Don't get sucked into to paying for anything that claims to charge you phone faster, just use the one that comes with the phone and you should be fine.
