Defective USB Wall Adapters
Hello, you are receiving this email because you purchased one of these CHC GNSS receivers from iGage:
i73, i83, i89, i93
There is a 20% chance (see discussion below for details) that the wall adapter is defective.
The iBase is not affected. We know of no iGage iG5 receiver kits that are affected.
This is not a safety issue, however a bad wall adapter will result in the receiver appearing to charge (LED’s will blink, displays will indicate charging), however the receiver will not charge.
If you think you have such a device, please email the receiver SN and your preferred delivery address to orders@igage.com and we will send you a replacement charger at no cost. Or call 801-412-0011 x12.
When you receive the replacement, you can destroy the existing charger or continue to use it.
If the receiver has been transferred to another individual, please let them know that new chargers are available.
Call or email us if you have any questions! Thank you very much for purchasing GNSS receivers from iGage Mapping Corporation.

Description of the adapter problem:
The affected chargers have a ‘defective’ charge controller that detects a lower-than expected power line voltage and refuses to output full charging current, limiting the output voltage to ~4.5 volts.
The adapters work on 220 V 50 Hz, 120 V 50 Hz and 120 V 60 Hz. (There has never been a complaint outside of the USA or Canada.) They fail at line voltages less than 120 V. We found that we can duplicate this issue more easily by putting a 100-foot extension cord in line with the wall socket.
The issue is not consistent, it may only happen 20% of the time.
The issue may not happen if you plug in the adapter with the cable disconnected, then plug in the cable after the adapter powers up.
The issue may happen on plugs that are at the end of a long distribution line or connected to a power-strip, but not happen if you plug the wall adapter in close to the circuit breaker panel. The issue may happen if another large load (air conditioner) is on and not happen when the load is off. The issue may be time of day dependent based on the distribution mains.
The issue may be dependent on the direction that Type-C cable is inserted into the receiver. (Believe it or not, the Type-C cable is not symmetric!)
To our knowledge there is no safety issue with the adapters, the issue is they are actually being too safe.
If you think you may have a defective adapter, don’t fight it. Let us send you a replacement!
