Have had this ‘Viking” branded unit for 5 months now, using it about twice monthly on one thing or another. The digital display is only 3 numbers (12.2 not 12.20) so a bit inaccurate but it does match the cheap red HF multimeter on voltages. Operation is easy, it auto senses 6/12v and has manual screen setup for FLA, AGM or GEL.
It also came with a handy-dandy direct plug with alligator clamps or a 3/8” closed loop wired tip for going onto the battery bolt. That’s handy as you can permanently install the latter onto the battery and then use the quick-disconnect/attach to hook up the little charger.
It’s basically as big as a common brick but 1/2 the weight. From the pic up top you can see the size relative to a riding mower battery.
Cost was $34 on sale with the 20% coupon which made it appx $30 after taxes. You can get their standard 10/2 amp non digital display charger for about $2-3 more when it’s on sale but I wanted the voltage display and will sacrifice the extra amps to have it.
