Streetwize Automatic Trickle Battery Charger – Keep Car, Motorbike, Motorhome, and Boat Batteries Fully Charged – Safe, Easy, and Reliable Indoor Charger

This is the second of these trickle chargers I have bought. The first I was very pleased with although then they only had two lights. Red for On and Charging and Red plus Green for Fully Charged. The new improved version which I have just received provides a useful third Amber light giving you the reassurance that the unit is charging and all is well. The unit is very reasonaby priced. Infact it is really quite cheap in comparison to some others but at any price this is a very good charger. Especially if used on a classic or other vehicle which is not run for long periods as it will not overcharge and kicks in and out as the voltage drops even just a little. This process also keeps the battery in good condition. By using this product the battery is always fully charged and ready for use.

I use my motor scooter occasionally so it can be parked in the garage for weeks. The alarm that’s fitted has a minimal drain on the battery but its still a drain. And, over time, the battery will run flat which does the battery no good. Leaving this plugged in and topping up the battery allows me to start the bike on the first press of the starter and the battery condition is maintained. There are two LEDs, red for power on and the green to show when its charging. The green LED goes out when the battery is fully charged which is opposite to what you'd expect. That doesn’t make it any less useful and it deserves the 5 stars I've given. It is far cheaper than,say, an optimate and (in my view) works better. I've had two other chargers, an oxford and an optimate and I'd recommend this one. The charge current isn't as high as the others I've mentioned but its not a rapid charger and never claimed to be.

Superb. We came back yesterday from 3 months in Spain, we’d left the var connected to this Trickle Charger and the cable was thin enough to shut the bonnet and the car started first time. Very happy customer.

Bought this to trickle charge my Harley Davidson motor bike during the winter months based upon the reviews here and of course the price. It comes with a selection of battery connection options which is really good, and has a LED display during operation which indicates the charging status. However it may not suit my application as in the instruction manual it states.. 1. "The battery should be disconnected during use" (I want to leave mine connected to the bike) 2. "Do not leave the charger unnattened for long periods of time" (I want it to maintain the battery charge during the winter months) 3. "When chaging is complete unplug the AD/DC power adaptor" (I want to maintain a battery and the bike alarm etc over a period of time) This appears to be contradicted later in the instructions by the statement that "The charging and discharging process will stop and start in a continuous state. In this way, even if the trickle charger is connected to the battery for a few months, the battery will be charged and fully active" So 4 stars from me due to the quality of the instructions and the obvious contradictions in the specification and mode of operation The minimum charging capacity for the battery is 7Ah, not stated in the instructions but indicated on the charger, so check before you purchase this item. For those that dont know when connecting the unit connect the red (+) first to the positive terminal and then the black (-) next to the negative terminal before connecting the unit to the mains supply. When disconnecting isolate the mains supply then disconnect the black (-) first and then the red (+).

Lifesaver in the winter or if your battery is on it's last legs.

Often in life things get "smart" to the detriment of usability, user interface and longevity and I find myself more frequently hunting out basic devices where the ethos is "keep it simple, stupid" - this is one such device. This cheap and cheerful charger is a small, inexpensive and basic charger that just gives a constant low rate of 1.5A charge, up to the point of meeting the required voltage, when it switches off. If you keep it attached, it waits for the voltage to drop a bit and then it switches back on. The three LED indicator lights tells you at what state it's in. Being "only" 1.5A it can take a while to charge (depending on the battery size) but low and slow is better for car/bike batteries as it prevents overheating and keeps the battery in better condition. I have a posh and expensive CTek battery conditioner but it's got very limited usability. They're fine if you know in advance you're going to be not using your vehicle (ie a classic car over winter), but as a way to revive and recharge a dead battery they're useless. The problem with "smart" battery conditioners/chargers is that they need the battery to have SOME charge (around 4V in the case of the CTek) to enable a feedback loop to say "yes, I need charging". But if your battery is dead, then it can't see that there's a battery attached and does nothing. A force trickle feature would be a good addition but alas there isn't. I hooked this baby up to my scooter battery (after 2.5months of not being used) and it's charging it nice and slowly and holding charge. This has saved me buying a new expensive battery.

This was just what I needed. It can be a little mind boggling if you have never bought a trickle charger before so allow me to help. If, like me, you don't use your bike during the winter months and the battery goes dead because of the tracker or the alarm, then this charger is what you need. Connect it to a fully charged battery, switch it on, and forget about it. It will maintain the voltage keeping the battery fully charged but without over charging it like ordinary chargers will. Instead, this charger switches itself on and off as the battery level drops and a little charge is required. This is perfect and ideal for maintaining a fully charged battery( you could not use an ordinary charger for that as it would cook the battery) but it is not really meant for charging a completely dead battery. So, use an ordinary charger to fully charge the battery first, then just connect this charger to keep your battery fully charged all winter.

This is a great, simple to use 12V charger. The usability issues reported by previous reviewers have been fixed: the model I received has three LEDs ("Power", "Charging", "Fully Charged") which make it completely unambiguous what's going on, although I note that the "Charging" LED does come on by itself when you connect the battery without mains power. There's no power on/off switch, so you have to switch it off and on at the wall. Arguably that's a feature, as it's one less thing to go wrong. All in all, does the job at a very reasonable price. With the car sitting unused on the drive due to Covid-19, at least I can keep the battery healthy!
