One of the questions I get asked fairly often is whether you should test every item before listing it on eBay.
My answer is simple.
Yes, whenever it’s reasonably possible.
Testing electronics before selling them on eBay has probably made me thousands of dollars over the years simply because buyers are willing to pay more when they know exactly what they’re getting.
That doesn’t mean every item requires hours of testing.
It doesn’t mean buying expensive equipment.
It simply means learning what you can reasonably verify before you create the listing.
Over the years I’ve tested thousands of used electronics before selling them on eBay, and I’ve found that the more I test, the fewer surprises I have after the sale.
That doesn’t mean I never sell untested items.
Sometimes I do.
I recently wrote about how I decide whether it’s worth buying untested electronics in the first place, because that’s usually where the process begins.
Usually that’s because I simply have too many items sitting in my unlisted inventory.
Many resellers call this a “death pile.”
If I have dozens or even hundreds of electronics waiting to be listed, I’ll occasionally group similar items together and sell them as an untested lot.
Someone else may have more time or enjoy testing every individual device.
If it can be tested in a few minutes, testing electronics for eBay is almost always worth the time because buyers are willing to pay more for a tested device.
Why I Prefer Testing
The biggest reason I test electronics is simple.
I want to know exactly what I’m selling.
If it powers on, I’ll say it powers on.
If the battery lasts five hours, I’ll mention that.
If one button doesn’t work, I’ll explain it.
If it only works while plugged into power, I’ll say that too.
The more information I can give buyers, the more confidence they have in purchasing from me.
That usually leads to happier buyers and fewer returns.
Battery Testing Adds More Value Than Most People Realize
One thing I think many sellers overlook is battery testing.
Take an older iPod Shuffle, for example.
An untested Shuffle might sell for around $10.
A tested one with a battery that plays continuously for five or more hours might sell for $40 or even $50.
That’s a huge difference.
The interesting part is that battery testing doesn’t require sitting there watching it the entire time.
I’ll fully charge the device first.
Then I’ll plug in headphones, start the music playing, and simply let it run.
After an hour, I’ll check whether it’s still playing.
If it is, I reset my timer for another hour.
The actual work only takes a few seconds each time.
Most of the testing happens while I’m doing completely different work.
If it finally stops after three hours, I’ll simply note that in my listing.
If it continues playing for five hours or longer, I’ll mention that instead.
That information is incredibly valuable to buyers because batteries are one of the biggest unknowns with older electronics.
Testing Doesn’t Have to Be Complicated
Many electronics only require a few simple checks.
Can it power on?
Does it charge?
Do the buttons work?
Does it play sound?
Does the screen look normal?
For cameras, I’ll usually take a quick photo, record a short video, and play it back to verify both the video and microphone work properly.
If the flash is working too, that’s another good sign.
Most of the time, that’s enough.
You don’t need laboratory testing.
You just need reasonable testing.
Sometimes a Bad Battery Is Immediately Obvious
Sometimes I don’t even need a long battery test.
I’ll fully charge a device.
Then I unplug it.
If it immediately shuts off…
the battery is almost certainly bad.
Other times I’ll watch the battery percentage drop dramatically after only a minute or two of normal use.
Those are valuable things to know before selling the item.
Instead of describing it as “working,” I can honestly explain that the battery needs replacement.
If I discover major problems during testing, I usually don’t repair the device myself, and I explain why in another article.
That usually means selling it for parts or repair instead.
Sometimes I Can’t Test an Item
Not every electronic can be tested.
Maybe I don’t own the correct charger.
Maybe I don’t have the correct battery.
Maybe buying those accessories wouldn’t make financial sense.
When that happens, I’m honest.
I’ll explain that the item is untested.
If it isn’t valuable enough to justify additional time or equipment, I may simply include it in a larger electronics lot instead.
Time and Money Both Matter
One thing I’ve learned over the years is that every decision has to make sense financially.
Sometimes replacing a battery is absolutely worth doing.
Other times it isn’t.
If spending $8 on a battery increases the value of an item by $100, that’s probably worth considering.
If replacing the battery requires expensive tools, complicated soldering, or an hour of work, I may decide it isn’t worth the effort.
Time is valuable too.
Experience Makes Testing Faster
Testing used to take me much longer.
Today it happens almost automatically.
I’ve accumulated chargers, cables, adapters, memory cards, and accessories over the years.
I know what to check.
I know which problems are common.
I also know when to stop testing because I’ve already learned enough about the item.
Experience speeds everything up.
The more experience you gain, the easier it becomes to decide whether something is even worth buying in the first place.
I Sell Plenty of Items for Parts
Testing doesn’t always mean an item becomes fully working.
I still sell many electronics for parts. I don’t believe tested vs untested electronics should automatically determine whether you buy or sell something. The decision depends on how much value a few minutes of testing adds.
The difference is that now I can explain why.
Instead of simply writing “untested,” I can tell buyers:
- No power.
- Battery won’t hold a charge.
- Works only while plugged in.
- Screen cracked.
- Touchscreen unresponsive.
- Doesn’t read discs.
That information helps buyers understand exactly what they’re purchasing.
When I create the listing, I also try to price it according to the condition I discovered during testing.
Many buyers specifically look for broken electronics because they repair them professionally.
Honesty Builds Trust
My goal isn’t to convince buyers every item is perfect.
My goal is to describe it accurately.
If something works, I say it works.
If something doesn’t work, I explain what I found.
If I couldn’t test it, I say that too.
I think that honesty is one reason I’ve had many repeat buyers over the years.
Final Thoughts
So…
should you test every item before selling on eBay?
Whenever it’s practical, yes.
You don’t need expensive equipment.
You don’t need to spend hours testing every device.
Most of the time, a few minutes of reasonable testing can dramatically increase both buyer confidence and the value of your listing.
Over time you’ll begin recognizing almost immediately whether an item is worth testing, worth repairing, worth selling for parts, or worth leaving behind altogether.
That’s also one of the biggest things I look for before I ever buy an item.
That experience only comes from buying, testing, and learning from your own results.
If you’re wondering whether it’s even worth buying untested electronics to begin with, I also wrote about the situations where I’ll take that risk—and when I’ll walk away.
